Description
Bluetooth Low Energy® (BLE) module of WT51822-S2 is the next generation BLE module released by Wireless-Tag. The modules use nRF51822-QFAA from NORDIC as the controller chips. With its small form factor, low power, high economic Bluetooth radio, WT51822-S2 can easily be added in your system and help to promote the design process.
