Pcb smd: common questions
What microcontroller does the Pcb smd use?
The Pcb smd is built around the ATmega32U4-MU, from the AVR/Arduino family.
How big is the Pcb smd?
The Pcb smd measures 53.3 × 47 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pcb smd?
46 components, from 21 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pcb smd design files?
From the rapidalarm/rapidalarm repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Pcb smd design in my own project?
The repository has no license, so all rights stay with rapidalarm. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pcb smd 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.
