Good hardware, docs lacking
Board works well but finding specific pinout info took time. Hardware quality is solid for the price point.

Perfect for IoT projects
Works flawlessly with Arduino IDE. The small form factor is a huge plus for compact designs. Wi-Fi connection is stable.

Low power consumption
Battery life is impressive on Bluetooth LE projects. Deep sleep modes work as expected. Highly recommend for battery projects.

Great board, tiny pins
Performance is excellent but soldering headers requires care due to size. Once set up, it runs very efficiently.
Q: Can I power it via battery directly?
A: Yes, via the VIN pin, recommended input range is 3.3V to 5V DC.
Q: Is external antenna supported?
A: No, this SuperMini model uses the onboard PCB antenna only.
Q: Is 5V tolerant on GPIO pins?
A: No, GPIOs are 3.3V logic level. Please use level shifters for 5V devices.
Q: Does it support MicroPython firmware?
A: Yes, this board is fully compatible with MicroPython and CircuitPython.
Q: What is the maximum current draw?
A: Peak current can reach around 350mA during Wi-Fi transmission. Ensure your power supply can handle this.
