Bluetooth Low Energy keyboard reference design
Description
This solution implements a keyboard for any operation system which supports HOGP (Hid Over GATT Profile). It is designed to have ultra low-power consumption for a substantial time working with Bluetooth Low Energy technology. CC2541 and an ultra-low-power MSP MCU are used in this design to handle BLE stack: key-matrix scan and power management work.
Features
- Low-power: 3mW average when typing at about 300 characters per minute Designed with TI Bluetooth Low Energy protocol stack include HOGP implementation Full-feature keyboard support up to 128 keys(16 x 8 matrix) without pcb modification Turnkey solution for BLE keyboard applications
