Description

A RPi Pico RP2350A microcontroller board in m.2 3024 size form factor with A and E key.

README

P42 Pico M.2

A RPi Pico RP2350A microcontroller board in m.2 3024 form factor with A and E key. The m.2 interface has USB, UART, I2C and control IO connectivity. Voltage levels for the m.2 specification are obeyed as some of the interfaces run on 1.8 V. Externally, +3.3 V, GND, the SWD interface and 16 IOs are accessible on castellated pins. A footprint for a QWIIC connector is on the top side of the board, not populated to have the board as low profile as possible. Power rail LEDs and a user controlled LED is on board, as well as a solder bridge for configuration options. Bottom side has a micro-SD card slot for data storage. A microcontroller could give any host computer flexible and excellent real-time IO and data processing capabilities. The RPi Pico with its programmable PIO interface has excellent timing resolution.

Full Feature List:

• M.2 2230-D5-AE card (22 mm x 30 mm; D5 = 1.5mm on top and bottom side violated by the QWIIC connector and the bottom SD card holder; A and E key)
• Used interfaces on the M.2: USB, UART, I2C, ALERT, WAKE, DISABLE1/2, LED 1/2, VENDOR_DEFINED
• 1.8V regulator for level-shifters
• Power LEDs for 3.3 V and 1.1 V
• RP2040/RP2350 peripherals: 2 MB Flash, SWD debug access, RESET and BOOTSEL button,
