Supplementary Fig. 5: LED polarity and orientation on the optoPlate illuminator.
From: High-throughput multicolor optogenetics in microwell plates
a) The polarity of the LED pads is indicated. b,c,d) LED polarity is typically indicated on the LED case with a clipped corner. The pole indicated by the clipped corner varies by LED part number, so always double check the LED product sheet before assembly. Proper orientation for LEDs in the 1-color (b), 2-color (c), and 3-color (d) configurations is depicted. Clipped corners are represented by red triangles.
