This board is a tiny USB to Qwiic development board in a bread-board friendly DIP form factor. In addition to micro USB and Qwiic connectors, it also has a reset button, RGB LED, and footprint for SPI flash expansion on the back of the board. The pinout and form factor are designed to be compatible with the Seeeduino XIAO board. The MCU is an NXP K32L2B Arm Cortex-M0+ with crystal-less USB and integrated VBUS to 3V regulator.
This board is currently supported by the open source TinyUSB and Adafruit's TinyUF2 to enable drag-n-drop firmware updates.
The KiCad source files are included in this repository along with a pdf copy of the schematic.
