Can you confirm the number of serial ports the Pixhawk 3 provides ?
This https://pixhawk.drotek.com/en/introduction.html documentation contradicts itself. It says:
“6 general purpose serial ports, 2 with full flow control, 1 with separate 1A current limit, 1 with FrSky protocol inverter.”
“Five serial ports are provided. TELEM 1, 2 and 3 feature full flow control. TELEM4 can be switched into inverted mode by hardware and has no flow control. Serial ports are 3.3V CMOS logic level, 5V tolerant, buffered and ESDprotected.”
Examination of the device pinout suggests 7 serial ports, see attached image.
Can you explain ?
Can you provide the schematic so I may confirm myself ? !
