About the Rev a PCB

Rev a is an open source Raspberry Pi PCB design by jackalkahwati, published on GitHub. It is a 4-layer board measuring 200 × 146 mm, with 154 components from 19 distinct parts.

Its main chip is the RaspberryPi_Pico_SMD_HandSolder, from the Raspberry Pi family. Other key parts include the SOIC-8_3.9x4.9mm_P1.27mm, MSOP-8_3x3mm_P0.65mm, SOT-23-5 and SOIC-20W_7.5x12.8mm_P1.27mm. By type, the board carries 91 relays, 27 ICs, 17 diodes, 9 fuses, 7 connectors and 3 resistors.

Rev a design files

The KiCad project lives in the jackalkahwati/EE-lab repository on GitHub; these links point at the commit this page was built from.

Rev a: common questions

What microcontroller does the Rev a use?

The Rev a is built around the RaspberryPi_Pico_SMD_HandSolder, from the Raspberry Pi family.

How big is the Rev a PCB?

The Rev a measures 200 × 146 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Rev a?

154 components, from 19 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 Rev a design files?

From the jackalkahwati/EE-lab 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 Rev a design in my own project?

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

Can I test firmware for the Rev a without the hardware?

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