RF-BM-BG22A1 www.szrfstar.comV1.0 - Sep., 2020 1. In principle, the module supports a minimum voltage of 1.71 V and a maximum voltage of 3.8 V. However, in order to be stable and reliable, it is recommended that customers use a DC power supply not lower than 2.2 V and not higher than 3.8 V. It is recommended to be 3.3 V. 2. The decoupling capacitor of the power supply is preferably 2.2µF. 4.4 Basic Operation of Hardware Design 1.
RF-BM-BG22A1 www.szrfstar.comV1.0 - Sep., 2020 weakened. 11. The recommendation of antenna layout. The inverted-F antenna position on PCB is free space electromagnetic radiation. The location and layout of antenna is a key factor to increase the data rate and transmission range. Therefore, the layout of the module antenna location and routing is recommended as follows: （1） Place the antenna on the edge(corner) of the PCB.
