The PGA2350 is a minimal but powerful RP2350B breakout board in a Pin Grid Array format, cramming the maximum number of exposed pins into the smallest possible space. At just 25.4 × 25.4 mm, it's designed to be embedded in projects where every millimetre counts.
It includes the essential components to run the RP2350B chip — crystal oscillator, voltage regulator, and support circuits — plus a generous 16 MB of flash storage and 8 MB of PSRAM. With 48 usable GPIO pins (18 more than a Raspberry Pi Pico), it's an incredibly capable board for its size.
Key Features
- RP2350B Processor – Dual Arm Cortex-M33 cores running at up to 150 MHz with 520 KB SRAM
- 16 MB QSPI Flash – Supporting execute-in-place (XiP)
- 8 MB PSRAM – CS wired to GP47 via cuttable trace
- 48 GPIO Pins – 8 with ADC capability, arranged in a 64-pin grid at 2.54 mm spacing
- Onboard 3.3V Regulator – Up to 300 mA output
- Input Voltage – 3V–5.5V (on VB pin only)
- Ultra Compact – 25.4 × 25.4 × 3.6 mm
- C/C++ and MicroPython – Programmable with both languages
Ideal For
- Space-constrained embedded projects
- Custom PCB integration
- Projects requiring maximum GPIO access
- High-performance MicroPython applications
Package Contents
- 1× PGA2350 board (header pins sold separately — 64 pins needed for full population)
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- Arm Cortex-M33
- A low-power Arm microcontroller core designed for real-time control tasks. It matters because it can handle timing-sensitive jobs such as reading sensors or driving motors while the main processor runs Linux.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- CS
- CS stands for chip select, a control pin used by SPI devices to tell which connected device should listen. It matters when you connect more than one SPI module to the same microcontroller, because each device usually needs its own CS pin.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- SRAM
- Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.
