The ESP32-S2 is great because it builds on the years of code and support for the ESP32 and also adds native USB support so you can use this board with Arduino \u003cem\u003eor\u003c\/em\u003e CircuitPython!\u003c\/p\u003e\u003cp\u003eWe designed this board to be low-power friendly - with a spot for a 350 or 420 mAh battery and built in battery charging over USB C. During deep sleep, with the NeoPixels and speaker amplifier disabled, we measured 250uA power draw so you can run for a few weeks between charges.\u003c\/p\u003e\u003cp\u003eAnd of course, the Mag in MagTag stands for \u003cem\u003emagnetic\u003c\/em\u003e. We have four M3 standoffs that will work perfectly with these mini magnet feet. (Originally they're designed for RGB Matrices but they'll do an excellent job here as well). Screw on the feet and you can attach this display to a metallic shelf, fridge, or bench.\u003c\/p\u003e\u003cp\u003eHere's the cool hardware we put together:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eESP32-S2 240MHz Tensilica processor \u003c\/strong\u003e- the next generation of ESP32, now with native USB so it can act like a keyboard\/mouse, MIDI device, disk drive, etc!\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWROVER module\u003c\/strong\u003e has FCC\/CE certification and comes with 4 MByte of Flash and 2 MByte of PSRAM - you can have huge data buffers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2.9\" grayscale display\u003c\/strong\u003e\u003cstrong\u003e with 296x128 pixels\u003c\/strong\u003e.
