RF32 Scoreboard

RF32 Scoreboard

Count points and control the scoreboard from your wrist.

The goal of the RF32 Scoreboard app is to enable athletes to count points in team sports. The app is dedicated to the iOS system. If you have some DIY enthusiasm, you can create a module that allows the app to control an external electronic LED scoreboard.

RF32 Bridge

What is it?

These are two devices: an ESP32 with a connected radio receiver and transmitter labeled CC1101. The code needed to run it is available in a public repository: https://github.com/jeremiDev/RF32-BLE-Bridge

Why is it needed?

The app and watch can work without it. However, if you want to control an external scoreboard via radio waves, you need this device.

How to build it?

  1. Buy an ESP32
  2. Buy a CC1101
  3. Connect the CC1101 to the ESP32. You can find the wiring diagram at: GitHub
  4. Flash RF32-BLE-Bridge onto the ESP32
  5. Launch the RF32 Scoreboard app
  6. Configure the connection with the Bridge during the first launch of the mobile app, or later through settings
  7. Done!
