Arm drive j2: common questions
What microcontroller does the Arm drive j2 use?
The Arm drive j2 is built around the 296-26344-1, from the ESP32 family.
How big is the Arm drive j2 PCB?
The Arm drive j2 measures 38 × 76 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Arm drive j2?
55 components, from 35 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 j2 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 j2 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 j2 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.
