IR_LED

This is an open-source infra-red illumnination solution (LED panel and driver) for machine vision. An arduino nano every sits at the core of the driver board, and allows remote control from a PC through serial communication

The main features are:

  • infra-red LED panel, with 3 separately addressable concentric rings
  • manual or remote control of the brightness for the 3 channels
  • LED driver can be strobed with the open-collector trigger output of a machine vision camera, which significantly reduces heat output
  • the temperature of the LED panel is measured in real time and can by controlled with a fan. The fan PWM can be set manually or via a software PID controller on the arduino

Questions

How big is the Panel 0 PCB?

It measures 115 × 75 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Panel 0 use?

54 parts, built around the SFH 4725AS A01. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Panel 0 KiCad files?

From the ElTinmar/IR_LED repository on GitHub, at the commit this page was made from: the board is hardware/LED_panel/panel_0/panel_0.kicad_pcb and its schematic hardware/LED_panel/panel_0/panel_0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Panel 0 design in my own project?

Its repository states no licence, so its author keeps all rights: ask ElTinmar before reusing the design.
