Bluetooth 4.0 LE single mode (KB) module

EBM-A21 is product from CSR's single-mode keyboard Bluetooth Low Energy solution. CSR μEnergy enables ultra low-power connectivity and basic data transfer for applications previously limited by the power consumption, size constraints and complexity of other wireless standards. The CSR μEnergy platform provides everything required to create a Bluetooth low energy product with RF, baseband, MCU, qualified Bluetooth v4.0 stack and customer application running on a single IC.
