Simple: common questions
What microcontroller does the Simple use?
The Simple is built around the RP2040, from the RP2040/RP2350 family.
How big is the Simple PCB?
The Simple measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Simple?
219 components, from 65 distinct parts. The full bill of materials is listed on this page.
Where can I download the Simple design files?
From the theacodes/kicanvas repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Simple design in my own project?
Yes, under the terms of its MIT license, which theacodes chose for the repository.
Can I test firmware for the Simple 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.
