About

FRCBatteryReader

Read full description

The FRC Battery Tag Reader is a companion utility designed for FIRST Robotics Competition (FRC) teams to streamline battery tracking and usage logging. Using NFC technology, this app reads and writes structured JSON records stored on NFC tags attached to robot batteries. With this tool, teams can: • Read battery information directly from NFC tags in the standardized JSON format. • Write new records (such as charging events or robot usage sessions) back to the tag. • Maintain history logs with a fixed number of entries, ensuring consistent data for every battery. • Export logs for analysis and recordkeeping. Hardware Requirements This app requires special hardware to function. It is designed to work with NFC tags written and managed by a compatible ESP32-based RFID system (see project repository for firmware and hardware details). Standard iOS devices with NFC can run the app, but the tags themselves must be prepared with the provided firmware and hardware setup. Open Source This project is fully open source! You can view the source code, contribute, or adapt it for your own team on GitHub FRC-RFID-Battery-Reader https://github.com/sikaxn/FRC-RFID-Battery-Reader/tree/main
