Brushless ESC: common questions
What microcontroller does the Brushless ESC use?
The Brushless ESC is built around the ATMEGA88PA-A, from the AVR/Arduino family.
How big is the Brushless ESC PCB?
The Brushless ESC measures 63 × 36 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Brushless ESC?
75 components, from 34 distinct parts. The full bill of materials is listed on this page.
Where can I download the Brushless ESC design files?
From the FordPrfkt/Brushless_ESC repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Brushless ESC design in my own project?
Yes, under the terms of its GPL-2.0 license, which FordPrfkt chose for the repository.
Can I test firmware for the Brushless ESC 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.
