Design Instruction
Similar to the Jetson™ TX2/TX2i development kit, the CSI interface is directly
connected between the Jetson™ TX2/TX2i module and the HDC on the Astro
carrier. There is no EMI/ESD protection along the signal path. It is
recommended to include this on the Breakout Board.
Power Input – HDC
The Astro Carrier accepts a single power input to power all on-board devices. While an input range of
+7.5V to +14.0V is acceptable, a 12.0V input is nominal for operation.
