Robot Main Controller V3: common questions
What microcontroller does the Robot Main Controller V3 use?
The Robot Main Controller V3 is built around the ESP32-WROVER-E, from the ESP32 family.
How big is the Robot Main Controller V3 PCB?
The Robot Main Controller V3 measures 130.5 × 91.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Robot Main Controller V3?
123 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the Robot Main Controller V3 design files?
From the manhtienvu-vn/Defensive_Robot 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 Main Controller V3 design in my own project?
The repository has no license, so all rights stay with manhtienvu-vn. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Robot Main Controller V3 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.
