- Output power: 30W (7MHz); 15W output for PIXIE 0.2W drive, 30W for BG6QBY Kit
- Working voltage: DC12 - 13.8V
- Working current: maximum 6A
- Transmitter and Receiver switch method: automatic
- PCB size: 60 x 100mm
- Net weight: 150g
Note:
- It has a heat dissipation board, but the heat dissipation fan is not included. It is recommended to equip a cooling fan for daily use.
- The power interfaces and component positions of several boards are slightly different, but they have the same circuit and performance. The specification of the power interface DC socket is 5.5 x 2.1, with internal positive and external negative. If your power interface is the same, you can directly plug it in. If your power interface is different, choose a universal interface without a DC socket. And then solder the power cord directly onto the solder pad, which can withstand a higher current.
Package Included:
- 1 x B Board
