Board: common questions
What microcontroller does the Board use?
The Board is built around the iCE40-LP8K-CM81, from the FPGA family.
How big is the Board?
The Board measures 71 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Board?
78 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the Board design files?
From the Roboy/bldc_motorboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Board design in my own project?
Yes, under the terms of its BSD-3-Clause license, which Roboy chose for the repository.
Can I test firmware for the Board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
