BeamBuddy: common questions
What microcontroller does the BeamBuddy use?
The BeamBuddy is built around the MCU-ATMEGA328P-AU_TQFP32_, from the AVR/Arduino family.
How big is the BeamBuddy PCB?
The BeamBuddy measures 84.5 × 41.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BeamBuddy?
58 components, from 27 distinct parts. The full bill of materials is listed on this page.
Where can I download the BeamBuddy design files?
From the adammhaile/BeamBuddy repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the BeamBuddy design in my own project?
Yes, under the terms of its MIT license, which adammhaile chose for the repository.
Can I test firmware for the BeamBuddy 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.
