This $5 board belongs in every smart home


The ESP32-C6 doesn’t look like much at first glance. It’s small, cheap, and the kind of thing I tend to lose in a drawer.

But if you look closer, you’ll find a tiny board that packs almost everything you need to build your own custom smart home device. You get wireless connectivity, general-purpose input and output, and full sensor support right out of the box.

It makes it easy to solve the specific problems that off-the-shelf gadgets tend to ignore. Instead of settling for a pre-made device that almost does what you want, you can build something that does exactly what you need it to do.

The smart home still has too many gaps

The smart home market is full of a huge range of products, but it still has shortcomings. You can buy smart bulbs, plugs, and thermostats all day long, but it’s much harder to find a device that’ll work nicely with your freezer, a specific garage layout, or a bathroom fan that reacts intelligently to humidity instead of just running on a timer.

This is where DIY hardware can shine. A custom device only has to solve your specific problem; it doesn’t need a mass-market appeal or an app that works for millions of people on dozens of different devices.

The ESP32-C6 is a great place to start. It is a tiny, cheap, wireless brain you can build into a custom smart device for $5.

A smart device needs more than just an internet connection; it needs a way to connect to sensors and control physical components. The ESP32-C6 supports up to 30 GPIO pins depending on your model. Some of those pins have an analog-to-digital-converter (ADC), enabling you to work with analog components, and others feature support for SPI, UART, I2C, and JTAG.

That mix of physical input and output options ensures you have plenty of options. You can use the board to read a button, monitor a door contact, talk to a temperature sensor, or power an LED.

Its wireless mix fits any smart home

The wireless support on the ESP32-C6 is a big part of what makes it such an interesting option for a range of DIY smart home projects. Out of the box, it supports 2.4GHz Wi-Fi 6, Bluetooth Low Energy (BLE), and Thread and Zigbee.

You won’t need all of these for every project—a freezer alarm might only need Wi-Fi, while a presence sensor might leverage Bluetooth—but the value is in the flexibility. You aren’t locking yourself into a board that only works with one or two wireless standards. Once you’re familiar with the ESP32-C6, you can adapt it to multiple different projects without worrying about whether or not it’ll be able to communicate, and without needing to relearn a whole new board.

It is perfect for small devices

The ESP32-C6 is especially compelling for tiny devices. You can use it to build a humidity sensor that triggers a fan, a freezer monitor to warn you before food spoils, a leak detector you embed in your shower wall, or a button panel that lets you trigger routines without having to reach for your phone, and they could be as small as a bottle cap.

Just keep in mind that while low-voltage sensors and LEDs are generally safe to tinker with, anything involving household power requires proper relay modules, isolation, and code-compliant wiring to be safe.

The ESP32 ecosystem is incredible

There are thousands of projects to draw from

Cheap microcontroller boards are everywhere, but the ESP32-C6 stands out because it belongs to a microcontroller family with a massive ecosystem behind it.

This means you aren’t starting from scratch on any project you attempt.

You have access to a huge library of tutorials, wiring diagrams, and community fixes for common builds. Whether you prefer Arduino-style tools, MicroPython, or the ESP-IDF framework, you have options.

If you use Home Assistant, you should definitely look into ESPHome. Instead of writing a full embedded program, you can simply define your sensors and relays in configuration files and flash the board.

Not only is it physically capable, the surrounding support makes it very compelling for beginners and experienced developers alike.


The ESP32-C6 is a great “brain” for any smart device

The ESP32-C6 won’t replace the central hub in your house unless you go to extraordinary lengths, but that’s okay—that isn’t its job. It gives you an inexpensive, flexible foundation for the specific devices big companies don’t bother to make, or allows you to build your own version for less that is specifically tailored to your needs.

Between the IO pins for real-world interaction, the massive ecosystem for troubleshooting, and a wireless mix that fits any modern smart home, it’s a great value. The future of your home automation might just be a five-dollar board hidden inside something you made smart yourself.

You’ve built your small business from the ground up. It’s your pride and joy, your financial security, and a potential legacy for your family. But what happens to your business interests after you’re gone? Without proper estate planning, your small business could face a chaotic future, disrupting operations, hurting employees, and jeopardizing your loved ones’ inheritance.

Business estate planning is your secret weapon. It’s not just for the ultra-wealthy with complex trusts and wills. For small business owners, it’s a crucial tool to ensure business continuity and protect your business value. Here’s how you can craft a comprehensive estate plan:

Know Your Business Inside and Out

The first step in your estate planning process is taking a deep dive into your business affairs. Make a list of all your business assets: equipment, inventory, intellectual property, and real estate.

Furthermore, don’t forget your business debts like loans and outstanding payments. This comprehensive list helps you understand what needs protecting and planning for in your estate planning documents.

Chart Your Business’s Future Course

What do you envision for your business after you’re gone? Should it stay in the family? Be sold to a trusted partner? Wind down entirely? This is where business succession planning comes in. It’s about deciding the future of your business in a way that honors your legacy and sets your team up for success.

Here are some questions to consider:

  • Family Business? Do you have a family member who shares your passion and has the skills to lead?
  • Trusted Partner? Is there a key employee you see as the ideal successor?
  • Time for a Change? Are you open to selling the business to ensure a smooth transition?

There’s no right or wrong answer. The key is to have open conversations with your loved ones and key employees to understand their goals and aspirations. This will guide you in crafting a business succession plan that feels right for everyone involved.

Develop a Rock-Solid Business Succession Plan

This plan outlines who will take over your business and how. You might identify a family member, a key employee, or even an outside buyer. The business succession plan should detail the transfer process, including training and timeline.

Here’s how to craft a plan as strong as your business itself:

  • Identify Your Successor: It could be a family member you’ve been mentoring, a trusted key employee, or even an outside buyer.
  • Groom Your Successor: Start by involving them in key decisions to give them opportunities to learn the ropes.
  • Plan for the Unexpected: Have a backup plan in place. Identifying another potential leader or outline a buy-out option for remaining partners.

Avoid Conflict with Ironclad Sell Agreements

If you have co-owners, a sell agreement is vital. This agreement dictates what happens to a deceased or incapacitated owner’s share of the business. It prevents conflict among remaining partners and ensures a smooth ownership transition in your overall estate plan.

Wills vs. Trusts: Choosing the Right Tool

A will can designate who inherits your business assets. But the problem is it can be a slow and public process through probate court.

Here’s where a revocable living trust comes in. Think of it as a private vault that holds your business assets during your lifetime. You can name yourself as trustee, so you’re still in control.

Another thing, you can designate a successor trustee to seamlessly take over managing the business if you become disabled or pass away. This avoids probate and keeps things running smoothly for your loved ones and your employees.

Wills are still important for your overall estate plan, especially for personal assets outside the trust. But for your business, a revocable living trust offers flexibility, privacy, and peace of mind.

Minimize Estate Taxes Through Strategic Planning

Nobody wants a big chunk of their hard-earned business value going to the government after they’re gone. That’s where estate taxes come in, and they can be a real burden for your family. But don’t worry, there are smart estate planning strategies you can use to minimize the impact of these taxes.

  • Smart Business Structure: The legal entity you choose for your business can impact your estate taxes. Talk to your estate planning attorney about structuring your business as a limited liability company (LLC) or another entity that might offer tax advantages.
  • Explore Powerful Trusts: There are special types of trusts, like grantor retained annuity trusts (GRATs), that can be used to transfer ownership of your business interests to your heirs while minimizing the taxable value of those assets.

The right strategy for you will depend on your specific situation and goals. That’s why it’s crucial to work with an experienced estate planning attorney and financial advisor. They can help you create a personalized plan that minimizes your estate taxes and protects your legacy.

Don’t Neglect Your Personal Estate Plan

Your business is just one piece of the puzzle. You also need a personal estate plan that includes a will, power of attorney, and healthcare directives. Without it, your loved ones could face a legal mess during tough times. Bills might go unpaid, important decisions could be delayed, and family heirlooms could end up in the wrong hands.

An estate plan ensures your wishes are followed. It names guardians for your minor children, designates beneficiaries for your personal assets (like your home and savings), and appoints someone you trust to make healthcare decisions if you’re unable to. This gives your family peace of mind knowing they’re taken care of, even in your absence.

Life Insurance: A Lifeline for Your Loved Ones

A life insurance policy provides your beneficiaries with a lump sum of cash upon your death. This can be crucial for surviving family members or business partners, especially if they need to buy out another owner’s share through a sell agreement or pay estate taxes.

Regularly Review and Update Your Plan

Life circumstances change, and so should your estate plan. Regularly review your plan, especially after major life events like marriage, children, or changes in your business structure.

Seek Professional Guidance for a Comprehensive Plan

Business estate planning involves complex legal and financial considerations. Don’t try to go it alone. Consult with an experienced estate planning attorney specializing in business succession planning and a financial advisor with experience in small business matters. Their expertise can ensure your estate plan is comprehensive, legally sound, and achieves your goals for business continuity and protecting your loved ones.

Final Thoughts

Safeguarding your business is like protecting your family’s future. Take control. Schedule a consultation with an experienced estate planning attorney today. They’ll guide you through the process and ensure your legacy lives on.
