All three are also supported by a GitHub repository, which includes full schematics, 3D models, and KiCad footprints, with Fritzing part files to follow in the near future. All the boards use a USB Type-C connector for data and power, with USB JTAG debugging plus a dedicated JTAG header on the ProS3, and include a user-addressable RGB LED.Īll three boards are built with CircuitPython in mind, though Rozenblum confirms that they can be programmed using MicroPython, the Arduino IDE, or Espressif's own ESP-IDF as well.
It does, however, drop to a single STEMMA QT/Qwiic connector - and comes with the promise of full protection from electrostatic discharge (ESD). Finally, the ProS3 switches to an even longer gumstick form factor with castellated pin pads, allowing for use as a surface-mount module, and comes 27 GPIO pins, two LDOs, and a microblade connector for a battery.
