Assembling the ELED01 PCB

The purpose of the ELED01 PCB kit is two-fold:

(1) It functions as an LED ring light for the end effector. This provides illumination for the camera.

(2) It is intended to be an PnP Practice Kit for FirePick Delta. It is the perfect test-piece to get familiarized with OpenPnP and the rest of the system!

Depending on your needs, you may do any of the following:

(A) assemble the bare PCB into the end effector and save the assembly work for later. If this is the case, your're done! You can exit this guide.

(B) Assemble it manually with a solder iron, tweezers, and optionally a stereo microscope. If this is the case, continue on to step 3.

(C) Use your FirePick Delta and OpenPnP to place the SMT parts on this board. If this is the case, stay tuned, we'll have a guide for this up soon.

Solder LEDs, then resistors, then FET and capacitor

Refer to the schematic and PCB layout posted to Github.

Ensure that the LEDs are oriented correctly; They are polarity sensitive. The green stripe must be on the cathode side.

Greg Smart has proposed an experimental rework step that allows for the LEDs to be the correct brightness. The modification involves cutting the traces between LED1 & LED2, LED3 & LED4, etc, and adding rework wires to connect them in parallel instead of in series.

This is technically not great for the life of the LEDs, as some forum members have pointed out, however it does work in a pinch.
