This is a 25x25mm board intended for integration into other projects based on RP2040.
All 30 GPIO pins, SWD, reset, and BOOTSEL broken out to 2.0mm pitch castellated pads
8MB onboard QSPI Flash
3.3V ultra low drop out linear regulator. Max 500mA output, 5.5V input.
May be directly powered from 3.3V. 5V pin should be left floating in this configuration.
Neopixel on GPIO17 ( with cuttable jumpers to disable)
LED on GPIO0 (with cuttable jumper to disable)
Onboard 27 Ohm USB D+/D- terminal resistors.
Lots of capacitors!
