P42 Pico2 M.2

A RPi Pico RP2350A microcontroller board in m.2 3024 size 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 QWIIC connector is on the top side of the board. 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, the push-buttons and the bottom SD card holder; A and E key)
• Dual Cortex-M33 or Hazard3 processors at up to 150MHz and 520KB of SRAM
• 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
• RP2350 peripherals: 2 MB Flash, SWD debug access, RESET and BOOTSEL button, SPI, I2C, UART, 12-bit 500 KSps ADCs, PWM, Timer, PIO
• QWIIC connector, 1 LED, 1 solder bridge for configuration, 16 GPIOs on castellated pins
• castellated pins on 25.4 mm/0.1" raster per side (with a 22 mm board)
• optional uSD card holder on the bottom side
• optional pull-down resistors on castellated IOs to mitigate the E9 Erratum

Mechanical Considerations

The SD card holder on the bottom side has a thickness of 1.57mm with inserted SD card. Some M.2 configurations have less clearance on the bottom side. The SD card holder without an inserted card is 1.42mm high. Also, if the SD card is used together with TP9, TP11, TP13 or TP16; make sure that no solder or wire is protruding on the bottom side, to not interfere with the SD card insertion area.
