Its main chip is the C41378174, from the RP2040/RP2350 family. Other key parts include the C53352, C556901, C205964 and C151353. By type, the board carries 21 capacitors, 12 resistors, 7 connectors, 5 ICs, 3 diodes and 2 switches.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

RP2354A development board with switchable voltage, QSPI breakout, and more

Pico 2V is an RP2350 development board that is (mostly) pin-compatible with the official Raspberry Pi Pico 2 board, but with some additional features and changes:

Switchable 3.3V/1.8V GPIOs: the official Pico 2 only supports running at 3.3V. Pico 2V has a jumper that lets you select between 3.3V and 1.8V. QSPI breakout: the official Pico 2 has an RP2350A as the chip, with on-board flash wired to the RP2350A's QSPI interface. Pico 2V has on RP2354A instead, which has 2MiB on-chip flash. As such, the RP2354A's QSPI interface on Pico 2V is broken out into two headers that can fit an SOIC-8…

Pico-2v: common questions

What microcontroller does the Pico-2v use?

The Pico-2v is built around the C41378174, from the RP2040/RP2350 family.

How big is the Pico-2v PCB?

The Pico-2v measures 51.5 × 21 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the Pico-2v?

51 components, from 25 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Pico-2v design files?

From the lucasbaizer/pico-2v repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Pico-2v design in my own project?

The repository has no license, so all rights stay with lucasbaizer. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Pico-2v without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
