From the project

A collection and an archive of KiCad projects I made. Contains projects from 2023 - 2024.

- Pico2040 and Pico2350 series. These are my self-designed boards oriented mostly around ARM microcontrollers. especially the RP2040 and the RP2350 - LiPower, BreadPower and LCDRucksack. Those are two board categories that I like to classify them as being "useless". LiPower being the overengineered version of the TP4056 charger, BreadPower being the most generic breadboard power supply. Of course, this was designed before I even know USB-C PD. LCDRucksack is just literally a clone of the LCD backpacks out there, but with castellated holes. - ProyekOPSI2023 was the board I designed for the…

Pico2350-W-Pro-R2: common questions

What microcontroller does the Pico2350-W-Pro-R2 use?

The Pico2350-W-Pro-R2 is built around the ESP32-S3R8, from the RP2040/RP2350 family.

How big is the Pico2350-W-Pro-R2 PCB?

The Pico2350-W-Pro-R2 measures 21 × 51 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pico2350-W-Pro-R2?

69 components, from 51 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 Pico2350-W-Pro-R2 design files?

From the zeankundev/boards 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 Pico2350-W-Pro-R2 design in my own project?

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

Can I test firmware for the Pico2350-W-Pro-R2 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.
