This page details the N6Cam IO Header pinout & functions.

Table of Contents

Overview

The N6Cam IO Header provides:

  • Power supply lines

  • Communication:

    • UART lines

  • GPIO:

    • Encoder

      • A, B, Z input phase

    • PWM

Power Port

If USB-C is not desired, an alternate power input port is available (black box):

  • 5 VDC @ 1.5 A
