GWBMD0x Datasheet
GWBMD0x Bluetooth Low Energy Module
1. General Description
GWBMD0xx is a Bluetooth low energy module based on Nordic Semiconductor‘s nRF51822 BLE
protocol processor. This module has integrated most of the peripheral components as RF matching
network, Antenna, 16MHz/32.768KHz Crystal, and DC/DC inductor, thus make it easy to be used in the
application circuit without knowing the RF design technics.
This is a pre-approved module. It reduces the work and cost for a range of qualifications and let our
customers to delivery their products to market more efficiently.
2. Applications
