surprised how easy it was to program this with esp-home and since then it has been working as a bluetooth bridge in home assistant without any issues. Great little product that has been rock solid.

Work perfectly for various IoTs projects. Easy to program and reliable, so far, I had zero issue. The only downside is related to the size of the reset button, way too small for my fingers... but no big deal.

This SOC microcontroller really is amazing. It's formfactor and capabilities are astonishing. Great for DIY Iot projects.

Cute little board. Expect to write C and not C++ in Arduino to get full functionality. Arduino IDE works but it's sketchy

This is currently my favorite project board. I love the different communication options and the size. I love that I can recharge my battery with it too.

Update 5/1/25: The little flex antenna doesn’t work any better than the ceramic one and the higher gain antennas I have found do not improve bluetooth performance at all. In fact the 8db gain antennas I bought are *extremely* directional to bluetooth signals to the point that they don’t get anything from 10ft away if not aligned very precisely, though they do improve wifi signaling mightily in every orientation I tried. I upgraded the cores when I made a new pi4 build platform but it did not fix one glaring issue with these - the pin numbers in the tooling does not match the silkscreening on the part. For example with pin 2 designated as an output the signal appears on pin 0. Update: The 3.0.0 cores I updated to are dev, not stable. The Serial2 port doesn’t work on any esp32 core unless you explicitly declare a new hardwareserial object, for wroom do the begin call with the pin number parameters provided and those are rx=16 and tx=17 iirc. For c3 and c6 both accept the begin call with only the baud rate parameter iirc. Original: I have some BLE code running on wroom boards and tried converting to the c6 with little success, could be my methodology. I build using arduino-cli on headless Libre ROC boards. I upgraded the cores and added the XIAO ESP32C6 which was quite painful and then made some slight changes to my existing code to accommodate some slight refactoring done in the newer BLE libraries. That code runs fine on the old wroom boards built with the new core updates. Building for the c6 was not much trouble but the code didn’t work at all. I built a simple blink sketch and it did work but the serial.print statements never appear. No idea what is causing that but the led did blink as expected. It was probably wishful thinking that the change over would be simple. I don’t need any feature of the c6 so I’m going to try Seeeds c3 version.

The most compact ESP32 money can buy. Works flawlessly and is a powerhouse of processing power for the size. highly recommend!

Great chip super compact would have been amazing if they would take WLED. I’ve tried the work around to no avail but still so much capabilities in such a little Chip you can fit this little guy Just anywhere just as easy to use as any ESP 32 and for pennies on the dollar you can’t complain

Does come with pins! Pins are not soldered on

The product works perfectly and integrates quickly and stable with Home Assistant for my project, the only regret is that I didn't purchase more pieces.

Livre sans antenne donc inutilisable

バーチャルマシン上のHome Assistantで使っています。

seems ok but time will tell
