Great value for money
Switched from ESP8266 to this. The RISC-V architecture is fast and efficient. USB-C is convenient.

Perfect for E-Paper Projects
Works flawlessly with my 2.9 inch e-ink display. Low power consumption is a huge plus.

Good board, minor documentation issues
Hardware is solid. WiFi range is decent. Wish the pinout diagram was clearer in the box.

Easy to program
Works straight out of the box with Arduino IDE. No driver installation headaches on Windows 11.

Solid performance
Using it for sensor nodes. Bluetooth pairing is stable. Only wish it had more ADC pins.
Q: Can it drive a 7.5 inch e-ink screen directly?
A: It can interface via SPI, but ensure level shifting if the display requires 5V logic.
Q: What is the maximum current per GPIO?
A: Each GPIO pin can source or sink up to 40mA.
Q: Does this support MicroPython?
A: Yes, it is fully compatible with MicroPython and CircuitPython.
Q: Is the USB-C port for data or power only?
A: The USB-C port supports both power delivery and data programming.
Q: Does it come with headers soldered?
A: This variant comes with unsoldered pin headers included in the package.
