## Description

A minimal but powerful RP2350 breakout board modelled on a Pin Grid Array, with the maximum exposed pins crammed into the smallest possible space.

PGA2350 is a **compact RP2350 breakout** designed to be embedded in projects where space is limited. It contains the components necessary to run the mighty RP2350B chip (that's the crystal, regulator and essential support circuits), a beefy **8MB of PSRAM** and a prodigious **16MB of flash storage**. Note that it has no LEDs, buttons or USB connectors - you'll need to attach your own USB connector to be able to program it.

All this drastic pruning means you get a small 25.4mm square footprint and **a lot of exposed RP2350 pins** to play with. 48 of them can be used as general purpose I/O (that's eighteen more I/O than on a Raspberry Pi Pico!) and 8 are ADC-equipped. Pimoroni has even managed to squeeze in some tiny pin labels to help identify them.

**Header pins are sold separately** - you can use [header pins](https://core-electronics.com.au/header-male-pin-01x20.html) (though bear in mind you'll need 64 pins if you want to populate it fully).

**Features**

- Powered by RP2350B (Dual Arm Cortex M33 running at up to 150MHz with 520KB of SRAM)
- 16MB of QSPI flash supporting XiP
- 8MB PSRAM (CS wired to GP47 via cuttable trace)
- Crystal oscillator
- On-board 3V3 regulator (max regulator current output 300mA)
- 64 pins, arranged with 2.54mm (0.1") spacing in a Pin Grid Array
- 48 multi-function General Purpose IO (8 can be used for ADC)
- 6 GND pins
- Input voltage range 3V - 5.5V (on VB pin only)
- Measurements: approx 25.4mm x 25.4mm x 3.6mm (L x W x H)
- Programmable with C/C++ or MicroPython

**Getting Started**

- [RP2350 MicroPython builds and examples](https://github.com/pimoroni/pimoroni-pico-rp2350)
 
**Notes**

- To program PGA2350 via USB you will need to hook wires up to VB, GND, U+ and U-. Make sure that the 5v **only** goes to VB on PGA2350, if it ends up elsewhere it will result in a bad time. A [USB breakout board](https://core-electronics.com.au/micro-usb-breakout-board-supports-otg.html) is a convenient way of getting at the wires in your USB cable.
- To get into BOOTSEL mode so you can flash firmware to your PGA2350, connect the BS pin to ground with a convenient bit of metal whilst plugging the USB into your computer.
 
**About RP2350**

The RP2350 chip is the Double Quarter Pounder & Fries to the RP2040's Double Cheeseburger and can have one or more RISC-V burgers instead of either of the M33 ARMs, to stretch the metaphor.

In addition to the modern M33 ARM cores, there are sides of: more PIO capability, a variety of low power states for sipping electrons, a whole security system and some sprinklings of specialist digital video circuits to offload DVI/HDMI output.

You can expect a tasty boost in performance - our "real world" MicroPython tests are running up to 2x faster compared to RP2040, and floating point number crunching in C/C++ is up to 20x faster. The extra on-chip RAM will make a big difference when performing memory intensive operations (such as working with higher resolution displays) and even more can be added thanks to external PSRAM support.

RP2350 comes in two flavours - A (standard) and B (all the pins). The B chip has a stonking 48 usable GPIO pins, including 8 ADCs and 24 PWMs, and features on some of our new products.
