Overview
ESP32-S3 based robot controller designed for combat robots in the 150g weight class
The controller can control 2 DC-motors for vehicle movement and an ESC for the main weapon. The board also embeds a 3-axis gyroscope and accelerometer which can be used to improve vehicle handling or detect when the robot is flipped. Wireless control is enabled through an integrated 2.4GHz PCB-antenna supporting both WiFi and Bluetooth.
Schematic and Layout
Firmware
The esp32 firmware is being developed in C using the ESP-IDF framework. Installation and build instructions from: ESP-IDF API reference

Questions
How big is the Battle bot pcb PCB?
It measures 45.8 × 30.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Battle bot pcb use?
66 parts, built around the ESP32-S3, DRV8833RTYR, TPS62172DSG and LSM6DS3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Battle bot pcb KiCad files?
From the MarkusVLA/robot-controller repository on GitHub, at the commit this page was made from: the board is PCB/Battle_bot_pcb.kicad_pcb and its schematic PCB/Battle_bot_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Battle bot pcb design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
