Good value board
Works well out of the box. Only minor issue was needing to install drivers on Windows 7, but fine on Windows 10.
Q: What is the current limit per GPIO pin?
A: The maximum current per GPIO pin is 12mA. Total current should not exceed specifications.
Q: Can I power this with 3.3V directly?
A: Yes, you can supply 3.3V to the 3.3V pin, but ensure your source can handle the Wi-Fi current spikes.
Q: Is this compatible with MicroPython?
A: Yes, the ESP8266 chip fully supports MicroPython firmware.
Q: Can I use this for 5V logic sensors?
A: No, the logic level is 3.3V. You will need a logic level converter for 5V sensors to avoid damage.
Q: Does it come with headers soldered?
A: No, this module typically comes without headers soldered to allow for flexible mounting.
