Arm drive: common questions
What microcontroller does the Arm drive use?
The Arm drive is built around the 1028-RT6285GSP, from the ESP32 family.
How big is the Arm drive PCB?
The Arm drive measures 57.8 × 80 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Arm drive?
66 components, from 43 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 Arm drive design files?
From the robotique-udes/PCB repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Arm drive design in my own project?
Yes, under the terms of its MIT license, which robotique-udes chose for the repository.
Can I test firmware for the Arm drive without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
