The ESC V+ connection is an Input Voltage to the FC whilst RX, GPS and other connectors' +V+ pads carry output from the FC's onboard voltage regulators. + +In some cases VTX or camera connectors may offer VBAT voltage directly but due to voltage fluctuations induced by the motors the use of VBAT direct to VTXs or cameras is discouraged. +To minimise the risk to sensitive VTX hardware it is advisable to provide an additional high voltage regulator for such components. +Recommended continuous power draw for this high voltage VTX regulator is ~18W, tranlating to at least a 9V/2A part, and output voltage should be between 8-12V. + The pin configuration for the JST SH connector is as follows: | Pin # | Signal Name | Description |
