M031BT dual-mode gaming mouse solution

This solution uses Nuvoton M031BT series microcontroller with Bluetooth low energy 5.0 to implement BLE5.0 and 2.4G dual-mode wireless mouse solution. Compared with BLE4.2, BLE5.0 has twice the transmission speed, 4 times the transmission distance, and lower power consumption. It is suitable for Internet of Things, smart home, Bluetooth keyboard and mouse and other applications. Bluetooth mice can meet office needs, but e-sports players require higher mouse data transmission rates. M031BT supports users to develop their own wireless communication protocols to support higher data reporting rates.
