Frequently Asked Questions

What software frameworks are compatible with the Unexpected Maker ProS3?

The ProS3 is fully compatible with the Arduino IDE using the ESP32 board package, Espressif's official ESP-IDF framework for advanced development, and MicroPython for scripting. You must install the correct board definitions and drivers for the USB-C serial chip. The board typically appears as a COM or /dev/ttyUSB port for uploading code and serial debugging.

How do I power the ProS3 board for a portable application?

You can power the board via the USB-C port with a 5V supply or connect a 3.7V LiPo battery to the dedicated JST connector. The integrated charging circuit will manage battery charging when USB power is present. For lowest power consumption, utilize the ESP32-S3's deep sleep modes and disable unused peripherals in your firmware to significantly extend battery life in field deployments.

What is the pinout and how do I connect external sensors?

The board breaks out numerous GPIO pins supporting digital I/O, ADC, SPI, I2C, and UART. Consult the official Unexpected Maker pinout diagram to identify which pins are safe to use. Avoid pins used for internal functions like the USB serial or flash memory. For I2C sensors, connect SDA and SCL to the designated pins, ensuring you use appropriate pull-up resistors if not integrated on the sensor module itself.
