Drive 27A: common questions
What microcontroller does the Drive 27A use?
The Drive 27A is built around the 296-26344-1, from the ESP32 family.
How big is the Drive 27A PCB?
The Drive 27A measures 32.5 × 59.3 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Drive 27A?
50 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 Drive 27A 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 Drive 27A 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 Drive 27A 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.
