SeeedStudio - 2.4Ghz Low Power Consumption BLE4.0 Module (Not Include Antenna) 1616mm - DIY Maker Open Source BOOOLE

The modules use nRF51822 from NORDIC as the controller chips. With its small form factor, low power, high economic Bluetooth radio, nRF51-01 can easily be added in your system and help to promote the design process.

nRF51822 is an ultra-low power 2.4 GHz wireless System on Chip (SoC) integrating the nRF51 series 2.4 GHz transceiver, a 32 bit ARM? Cortex?-M0 CPU, flash memory, and analog and digital peripherals. nRF51822 can support Bluetooth? low energy and a range of proprietary 2.4 GHz protocols, such as Gazell from Nordic Semiconductor.
