Very easy to use compared to some of the other esp32 boards I've picked up from amazon. The serial IO usbc port connects seamlessly to my pc and I can very easily use platformIO or the arduino IDE to flash it and monitor serial output. Will definitely buy more for future IoT projects

I was dubious. But I use these little guys everywhere. Nice, low power consumption, very versatile. Easy to set up with the Arduino IDE (or similar environments), well-documented, and have had zero trouble with any of the I/O on the XIAO, despite my inadvertent, accidental attempts to put their tolerances to the test. These boards are one of my most frequently used project boards, and they find their way into the majority of my prototyping builds.

These were something of a chore to flash, but once you figure it out, they function great. they are really small and battery life is outstanding. i would certainly rebuy these.

One of the best microcontrollers imo, works so well and has through charging a 3.7v lipo battery pads on the bottom. This is my 2nd favorite microcontroller seeed makes. My all time fav is Xiao-mg24. It has everything this controller has but also has a microphone and accelerometer built on!

Lots of code support online for getting this up and running. Easily had it serving a website on my local network for remote control via ngrok, plus powered some pretty hefty motors with only USB power and no issues. Impressive for the price and size.

Very quickly becoming my favorite MCU, it can definitely be more powerful than needed, but after spending days googling and debugging cheaper and less powerful chips in the hopes of keeping dev costs down, i'd rather have a sturdy v6 under the hood than deal with an undocumented, poor designed 4 cylinder. Has less pins than your esp32 dev or wroom modules but if you need multiple serials and don't want to play the software serial bit bashing game, this thumb sized chip will do it without issue, i've yet to get that with the wroom even though it boasts supposedly 3 uarts.. Cheaper dual core, 4mb 160mhz can be had for between 4 and 7 bucks a piece, but with at least double the footprint, without onboard lithium charge host, 5v regulator that can handle solar input and so far really good support. you can even go cheaper with a single core for about 2 bucks each.. but the HOURS and HOURS googling issues or error messages because the seller has the entire support site in chinese, outdated pin out diagrams, narrow community support will each that savings up. seeed studio has a nice chat tool that quickly googlefu's for you results for error messages that might appear and quite a few peripheral providers (oleds, sensors) have xiao esp32 specific libraries available. definitely would grab several if they go on sale

These little ESP32C3s are an incredibly good package for the price. Very small, with a nice set of pin outs, a reasonably powerful SoC, and support for any number of external wifi antennas have made these my board of choice for a number of ESPHome powered automations, from weather stations to chicken coop monitoring equipment. It would be nice for the Amazon ones to offer a variant with headers soldered on, but its not really a terribly big deal to solder your own on.

It's a great little board. Now even easier to program using ChatGPT.

Is a nice small crazy computer
