Robot: common questions
What microcontroller does the Robot use?
The Robot is built around the ESP32-DEVKITC, from the ESP32 family.
How big is the Robot PCB?
The Robot measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Robot?
183 components, from 31 distinct parts. The full bill of materials is listed on this page.
Where can I download the Robot design files?
From the jgraulle/robot-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Robot design in my own project?
The repository has no license, so all rights stay with jgraulle. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Robot 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.
