BDCMotorController: common questions
What microcontroller does the BDCMotorController use?
The BDCMotorController is built around the ATMEGA2560-16AU, from the AVR/Arduino family.
How big is the BDCMotorController PCB?
The BDCMotorController measures 203.5 × 90 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the BDCMotorController?
313 components, from 72 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the BDCMotorController design files?
From the nunosousa/TelescopeMirrorTester repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the BDCMotorController design in my own project?
Yes, under the terms of its MIT license, which nunosousa chose for the repository.
Can I test firmware for the BDCMotorController 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.
