Rev a routed: common questions
What microcontroller does the Rev a routed use?
The Rev a routed is built around the RaspberryPi_Pico_SMD_HandSolder, from the Raspberry Pi family.
How big is the Rev a routed PCB?
The Rev a routed measures 200 × 175 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Rev a routed?
179 components, from 33 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 routed design files?
From the jackalkahwati/EE-lab repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Rev a routed 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 routed 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.
