4.2 Setting up Four IMX219 Cameras

Follow the instructions provided in the AM62A Starter Kit EVM Quick Start Guild to setup the SK-AM62A-LP EVM (AM62A SK) and ArduCam V3Link Camera Solution Quick Start Guide to connect the cameras to AM62A SK through the V3Link kit. Make sure the pins on the flex cables, cameras, V3Link board, and AM62A SK are all aligned properly.

Figure 4-1 shows the setup used for the reference design in this report. The main components in the setup includes:

  • 1X SK-AM62A-LP EVM board
  • 1X Arducam V3Link d-ch adapter board
  • FPC cable connecting Arducam V3Link to SK-AM62A
  • 4X V3Link camera adapters (serializers)
  • 4X RF coaxial cables to connect V3Link serializers to V3Link d-ch kit
  • 4X IMX219 cameras
  • 4X CSI-2 22 pin cables to connect cameras to serializers
  • Cables: HDMI™ cable, USB-C® to power SK-AM62A-LP and 12V power sourced for V3Link d-ch kit)
  • Other components not shown in Figure 4-1: micro-SD card, micro-USB cable to access SK-AM62A-LP, and Ethernet® for streaming
