Production (V1) Carrier Board Connectors
The NXP reference board design production version units have a slightly different connector set than what has tradionally been included in the standard V6X design and also the Holybro V6X-RT units.
The key differentiators are:
- No separate IO processor required. All PWMs including redundant coming from RT1176
100BaseT1 two wire ethernet
Additional SE05x secure element on the base board in addition to the FMUMRT1176
NFC antenna interface to secure element
DSM and AUX RC ports in addition to "RC IN"
Right side interfaces
They include:
CAN1, CAN2: Dual CAN-FD interfaces employing CAN-SIC (Signal Improvement) CAN phys.
Left Side Connections
CAN3: (extra additional ) CAN-FD interfaces employing CAN-SIC (Signal Improvement) CAN phys.
T1-ETH: 100BaseT1 Two wire 100MBPS Ethernet
TELEM1/2/3: 3x Telemetry ports with Hardware handshaking
Front side connectors
NFC: NFC connection to carrier board Secure Element. (interface may be accessible even when not powered?)
GPS1: PX4 full GPS connector including Arming Button interface, beeper, magnetometer and RGB LED
PWM and SBUS IBUS RC input
Typical connection for SBUS/IBUS input from RC remote controller. (note: Alternative RC interfaces possible)
Debugger and serial console connection
Use Cognipilot Neural probe or DCD-LZ-ADAPT or similar adapter to connect a debugger or serial console to the Pixhawk-debug-full port (AKA DCD-F)
Note the legend for the LEDs is actually shown above the 4 led holes in the enclosure.
ASEL analog input select indicator
Schematic showing alternative function. D5 = ASEL LED.
J14 pin 7 'ADC1_6v6_Aux', can be selected to connect either 'ADC1_6v6' or Vdd Servo rail to the ADC to read the voltage.
