Adafruit Circuit Playground: common questions
What microcontroller does the Adafruit Circuit Playground use?
The Adafruit Circuit Playground is built around the ATMEGA32U4-MU, from the AVR/Arduino family.
How big is the Adafruit Circuit Playground PCB?
The Adafruit Circuit Playground measures 61 × 60 mm, has 16 copper layers and is 1.6 mm thick.
How many components are on the Adafruit Circuit Playground?
78 components, from 40 distinct parts. The full bill of materials is listed on this page.
Where can I download the Adafruit Circuit Playground design files?
From the Human-Computer-Integration-Lab/ProtoPCB_Web repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Adafruit Circuit Playground design in my own project?
The repository has no license, so all rights stay with Human-Computer-Integration-Lab. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Adafruit Circuit Playground 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.
