Ni-MH Cell Charger SKYDROID FPV Receiver 5.8G OTG 150CH Video Downlink Receiver Double Antenna RC Aircraft and Quadcopter Maintenance:

RC Aircraft and Quadcopter Maintenance: Professional RC pilots use the B6AC to charge and balance LiPo battery packs before flights and discharge them after use

implement these techniques: use external antennas with higher gain (5-8dBi dipole or Yagi antennas) instead of the integrated antenna

The dongle itself is not recommended for production due to its USB form factor and integrated debugger overhead

Native USB: Appears as a virtual COM port - no external FTDI chip needed

and a 3D antenna for enhanced wireless connectivity
