Erc rover-EyP: common questions
What microcontroller does the Erc rover-EyP use?
The Erc rover-EyP is built around the ESP32, from the ESP32 family.
How big is the Erc rover-EyP PCB?
The Erc rover-EyP measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Erc rover-EyP?
72 components, from 47 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 Erc rover-EyP design files?
From the Matyy38/erc-rover-EyP 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 Erc rover-EyP design in my own project?
The repository has no license, so all rights stay with Matyy38. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Erc rover-EyP 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.
