70- keyboard: common questions

What microcontroller does the 70- keyboard use?

The 70- keyboard is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the 70- keyboard PCB?

The 70- keyboard measures 310.5 × 118.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 70- keyboard?

236 components, from 8 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 70- keyboard design files?

From the aaravs-s/70-_keyboard 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 70- keyboard design in my own project?

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

Can I test firmware for the 70- keyboard 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.
