Product Description

nRF****2 FCC approved pcb chip module from RF-star for ibeacon mesh module 


Overview

The Bluetooth module, which is offered by Shenzhen RF-star Technology Co.,Ltd., is based on low

power Bluetooth RF technology (BLE) , and can be widely used in applications of short distance

wireless communication, with the features of low power consumption, small size, long transmission

distance, strong anti-jamming capability, and etc. The module is built in with high-performance

inverted F antenna.

The module is helpful to develop consumer electronics products and smart phone peripheral

products, which are based on Bluetooth 4.0 (or BLE). It will provide a quick BLE solution to the

communication between customers products and smart mobile devices.

Layout Proposals

The serpentine antenna on PCB is free space electromagnetic radiation. The place and layout range

are keys to enhance the data rate and transmit range.

Thus，Below are the layout proposals for antenna and route:

1. Place the antenna on the edge(corner) of the PCB backplane.

2. Make sure there is no signal or copper foil in each layer.

3. Hollowing out the black pane part (figure 3) to make less S*1 interference
