Cheap price 2019 small bluetooth keyboard module

Product Description

SR-  ND02BLE01

 The SR-ND02BLE01 module is designed base on Nodic nRF51822 radio transceiver IC, the IC is an ultra-low power 2.4GHz wireless System On chip (SoC) integrating the nRF51 series 2.4GHz transceiver,a 32 bit ARM Cortex-M0 CPU, flash memory and analog and digital peripherals. The module can support Bluetooth low energy and a range of proprietary 2.4GHz Protocols.

The application engineers can easily apply the RF module for its application without worrying about the specific impedance matching or soldering fine pitch related radio designing issues.
