“Great board, small and compact but with everything you (well me at least) need! I've ordered the ESP32-C3 Zero with and without pins, and both times I was happy with my order.
Works great with WLED, and with an SD card module thingy for playing music.
The fact that it's USB-C means this will probably be my go to board for a while!!
100% would recommend this product.”
“The Waveshare “ESP32-C3 Zero Mini Development Board” is a neat little board, and an improvement on the ESP8266-D1mini as it has more GPIOs, and also BLE capability.
However note that the ESP32C3/design used on the original “ESP32-C3 Zero Mini Development Board” (eg. purchased May2024) has a very poor antenna matching network, which on it’s default Tx power setting often causes so much reflected power that it overloads it’s receiver and is often not able to connect to a WiFi network.
If this happens try dropping the Tx-Power by adding “WiFi.setTxPower(WIFI_POWER_8_5dBm);” after your “WiFi.begin(“. See https://github.com/espressif/arduino-esp32/issues/6767.”
“Absolutely blown away at how amazing this little board is considering the price point. BLE HID works amazingly (even though for ESP32 I needed to do some serious mods to example code) and it's a dream once you get going (Arduino setup can be complex but it's well documented). Be careful with that LED though, it seems to run super hot!”
