JHEMCU HDVTX Module O3 O4 5V 10V Step-down module reduces the input voltage at the sky end

The JHEMCU HDVTX Module is mainly used for the current AI0 or flight controller without built-in 10V BEC.
Especially the O4 Air Unit is a low voltage input range, the voltage greater than 3-6S is not suitable for directly supplying power to the O4 Air Unit, so it is necessary to connect this module in series to the VTX power supply between the VTX to reduce the input voltage of the O4 Air Unit, and at the same time, the TX RX SBUS signal is also straight-through to the output, which is not used to weld the signal line. Of course it can also be used for O3/O4 to reduce the input voltage and minimize the risk of high voltage shock to the VTX.


Input voltage:6.5-26V(2-6S)
Output Voltage:5V or 10V
Output current:5V 2.5A / 10V 2A
