PIMORONI PGA2350 RP2350B Breakout Board
Ultra-compact PIMORONI PGA2350 breakout board featuring RP2350B, 48 GPIO pins, 16MB flash & 8MB PSRAM. Ideal for embedded projects.
The PIMORONI PGA2350 is an ultra-compact RP2350B breakout board designed to provide the maximum number of pins in the smallest possible space. Contained within a tiny 25.4mm square footprint, it is perfectly suited for embedded projects where space is at a premium, without compromising on power or memory.
Powered by the RP2350B chip featuring a Dual Arm Cortex M33 processor running at up to 150MHz and 520KB of SRAM, this breakout board delivers robust performance. It includes 16MB of QSPI flash supporting Execute in Place (XiP) and 8MB of PSRAM, with the PSRAM chip select wired to GP47 via a cuttable trace. The board offers 64 pins with 2.54mm spacing in a pin grid array, comprising 48 multifunction general-purpose IO pins, 8 of which can be used for analogue-to-digital conversion (ADC).
Key Features:
- Onboard 3V3 regulator (max. current output 300mA)
- Input voltage range: 3-5.5V (VB pin only)
- Programmable with C/C++ or MicroPython
Important Notes:
There is no onboard USB connector; one must be attached for programming. To program via USB, wires need to be connected to the VB, GND, U+, and U- pins. To enter BOOTSEL mode for flashing firmware, connect the BS pin to ground using a piece of metal whilst plugging the USB into your PC. Ensure that 5V is connected only to the VB pin on the PGA2350.
