This is a board for Pimoroni that features the RP2350
Pimoroni Pico Plus 2 W is powered and programmable via USB-C and comes with an upgraded 8MB RAM, 16MB of flash storage and easy-to-read pin labels.
It's super easy to connect up to things without soldering, with a Qwiic/STEMMA QT connector (for adding I2C sensors and breakouts), a SP/CE connector (for hooking up SPI/serial devices) and a debug connector (for if you like to program using a SWD debugger).
It also has a reset button and a BOOT button – this can also be used as a user switch.
It has some updates compared to the official Raspberry Pi offering
- It has more storage (16 Mbyte versus 4 Mbyte)
- It has more RAM (8 Mbyte vs 0.5 Mbyte),
- It uses a USB-C versus micro USB
- Integrated reset button.
- Five extra GPIO pins are exposed which makes a total of 31 versus 26
Features
- Powered by RP2350B (Dual Arm Cortex M33 running at up to 150MHz with 520KB of SRAM)
- 16MB of QSPI flash supporting XiP
- 8MB of PSRAM
- USB-C connector for power, programming, and data transfer
- Qw/ST (Qwiic/STEMMA QT) connector for attaching breakouts
- Intriguing SP/CE connector
- 3-pin debug connector (JST-SH)
- Reset and BOOT buttons (the BOOT button can also be used as a user button)
- User LED indicator
- On-board 3V3 regulator (max regulator current output 600mA)
- Input voltage range 3V – 5.5V
- Compatible with Raspberry Pi Pico add-ons
- Measurements: approx 53mm x 21mm x 9mm (L x W x H, including connectors)
Here is the pinout
You can see a 3-pin debug connector on the top-right. Below is a 4-pin connector that carries I2C, 3.3V and GND. The I2C connections are already exposed on a couple of the castellated pads, they are GPIO 4 and GPIO 5.
The castellated pads are unusual in this boards design as there are components on both sides but it may be that this was a template for a board and the parts on the underside were added later, otherwise not sure why they are like that.
I never use these but be aware of this if you do use.

Notes
- The user LED is wired to GP25, just like on an ordinary Pico. You can blink it in exactly the same way!
- It is also useful for putting your Pico Plus 2 into bootloader mode, and you can also use the BOOT button as a user button. It's wired to GP45 and active low.
- Note – the wireless is stated as experimental, read https://github.com/pimoroni/pimoroni-pico-rp2350/releases/tag/v0.0.10
I have 2 of these and will be trying them out, especially the networking
