OBCv2: common questions
What microcontroller does the OBCv2 use?
The OBCv2 is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.
How big is the OBCv2 PCB?
The OBCv2 measures 80.5 × 80.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the OBCv2?
30 components, from 20 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 OBCv2 design files?
From the AfriOrbit/EduSat-Project 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 OBCv2 design in my own project?
The repository has no license, so all rights stay with AfriOrbit. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the OBCv2 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.
