Description: Battlemote is an ESP32-powered all-in-one remote controller for a battlebot.

Battlemote is a custom PCB project designed to control a battlebot.
It uses an ESP32 as the main microcontroller, features both button and joystick inputs, a TFT screen for feedback, and runs off a LiPo battery with onboard voltage regulation..

The goal of Battlemote is to provide a compact, fully integrated, and fun-to-use battlebot remote.

• MCU: ESP32-Supermini (initially Xiao ESP32-C3, later swapped)
• Inputs:
  • Joystick
  • Buttons
• Display: Adafruit 1.8" TFT Screen
• Power: 7.4V LiPo Battery
• Voltage Regulation: AMS1117-5.0
• Misc: Mounting holes, test points, custom silkscreen art

• Compact PCB remote layout inspired by the Sprig controller
• Joystick + button configuration for flexible control
• Integrated TFT display for UI and feedback
• Ground and power pours for stable operation
• Custom silkscreen and 3D-rendered board design

• Design & PCB Work:ork: ~37h
• Research & Datasheets:ets: ~5h
• Total: ~42h
