BabyHandsKeyboard: common questions

What microcontroller does the BabyHandsKeyboard use?

The BabyHandsKeyboard is built around the ProMicro, from the AVR/Arduino family.

How big is the BabyHandsKeyboard PCB?

The BabyHandsKeyboard measures 186.1 × 136.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BabyHandsKeyboard?

56 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the BabyHandsKeyboard design files?

From the FionaCutler/BabyHandsKeyboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the BabyHandsKeyboard design in my own project?

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

Can I test firmware for the BabyHandsKeyboard without the hardware?

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