30 mm Cage Plate LED MC
About the 30 mm Cage Plate LED MC PCB
30 mm Cage Plate LED MC is an open source PCB design by Llamero, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 40 × 40 mm, with 25 components from 14 distinct parts.
Other key parts include the AL8843QSP-13. By type, the board carries 6 diodes, 5 capacitors, 3 resistors, 2 transistors, 2 connectors and 1 IC.
From the project
LED mount that is compatible with the Thorlabs 30 mm cage plate
The LEDs on the board are closely spaced so that all four LEDs efficiently couple into a 5 mm liquid light guide or other optical paths.
Each board can drive up to four individual LEDs, and includes a thermistor for temperature monitoring. The the LED current is regulated by an AL8843, allowing LEDs to be driven with up to three amps of current. The AL8843 also allows for both PWM control as well as analog current control down to 10% of the current limit (see below for setting max current limit).
