MOKO’s Development--NRF51822 Module

The NRF51822 Bluetooth module is a powerful, highly flexible multiprotocol SOC ideally suited for Bluetooth low energy and 2.4GHz ultra low-power wireless applications. The NRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU with 256kB/128kB flash + 32kB/16kB RAM for improved application performance. The embedded 2.4GHz transceiver supports both Bluetooth low energy and the Nordic Gazell 2.4 GHz protocol stack which is on air compatible with the nRF24L series products from Nordic Semiconductor. MOKO technology Ltd provides all software and hardware to develop it. Here are specifications of NRF51822 Bluetooth module develop by MOKO.
