“This is much better than a Pico W for my purposes - way smaller, wifi seems more robust and less of a bolted-on afterthought, plenty of pins, and a neopixel on the board to boot. I use micropython - there doesn't seem to be a Waveshare-specific firmware but the generic Espressif build works fine.”
“Great little board. I was puzzled why the onboard LED appeared not to work. Eventually I discovered the way to do it in the Arduino ESP32 GPIO BlinkRGB sketch.
Just changed the pin to 10.”
“I bought three of these to try out and have not been disappointed.
This is a great little board. Very compact and a great way to create small projects with WiFi or Bluetooth included. There's plenty of PWM pins which is useful if you want to control lots of servos. I think it's a perfect upgrade over something like an Arduino Nano in many situations.
It's supported in the Arduino IDE environment. Just remember to set "USB CDC on Boot" to Enabled so the serial output works.”
“It's a neat little thing with lots of features and a variety of different systems for programming it (I'm currently using esphome). Also, very cheap at The Pi Hut.”
“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.”
