CONNECTOR PINOUTS OSD:
DB9 MALE, ORANGE COLOR
1 9V input (power from the cam remote ptz controller ??)
2 Temperature 1, input 1V max LM60 (T2 is internal)
3 BEC volt, RSSI input
4 V1 battery voltage 24V (from 24 to 9V converter)
5 Current Measure input (from sense resistor gain amplifier)
6 Gnd input
7 Gnd
8 R/C servo signal input for video selector
9 R/C servo signal input for OSD
electronics_smps_arduino.jpg Powersupply for all Arduino units, based on some old boards i designed many years ago PT6304R 16-38V input, 12V out 3A
I like this module a lot, for its wide input range, and wide output voltage trim, both up and down, very usefull, just too bad it is obsolete.
