BattleCore Headband Mainboard

The BattleCore Headband Mainboard is designed to fit on a headband with a 7.4V LiPo battery pack and connect up to 4 sensor modules around the headband for independent hit detection.

It features a dual-core processor, up to 4x wired sensor modules, a USB-C connector for development / firmware / serial, extra GPIO breakout pins for future connectivity, a press-button latch power circuit, battery temperature and battery charge level inputs, support for an I2C display, and both WiFi 2.4GHz and Bluetooth LE. OTA firmware updates are supported.

Designed to integrate cleanly with the rest of the BattleCore ecosystem while remaining usable as a standalone wearable mainboard for any project needing distributed sensor input.
