An open source RP2040 MCU Board Family

originally this was going to be a version that contains a battery charge IC and a ESP32 wireless slave but I feel like its a bad idea to combine things Ive not worked on before so I scaled back the project to have just a battery PMIC.

RP2040 Minimal Design Example: common questions

What microcontroller does the RP2040 Minimal Design Example use?

The RP2040 Minimal Design Example is built around the RP2040, from the RP2040/RP2350 family.

How big is the RP2040 Minimal Design Example PCB?

The RP2040 Minimal Design Example measures 21.2 × 51.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP2040 Minimal Design Example?

50 components, from 35 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 RP2040 Minimal Design Example design files?

From the Envious-Data/EnvOpenPico 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 RP2040 Minimal Design Example design in my own project?

Yes, under the terms of its GPL-3.0 license, which Envious-Data chose for the repository.

Can I test firmware for the RP2040 Minimal Design Example 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.
