1.Scope
The GEBW2455A module is a Bluetooth / WiFi Communication Module which provides the highest level
of integration for IoT applications handheld wireless systems ,with integrated
IEEE 802.11b/g/n(HT20)/ac and Bluetooth 5.0 + EDR (Enhanced Data Rate).
The diamention of the module is 7.9mm * 7.3mm, 3.35~ 4.2Vdc power supply. The module uses
stamp hold package so it is convienent for both hand soldering and surface mount machines.
GEBW2455A module can work when it is more than 20cm from the human body.
