Hi, thanks for taking the time to read this.
I don't fully trust my measurement, and I don't have enough knowledge of an expected value.
How much current would be expected to run two of these tiny LEDs on a ky-024 breakout?
I want to run 13 boards, and I was assuming I would need a 3.3v regulator in addition to the one on my teensie 4.0. (I know the picture shows a 3.2)
However, measuring the current drawn by the board when both LEDs are lit to full strength, I was only seeing draw of 6.5ma
That would suggest I could easily run all x13 for just 85ma - which my gut says is implausible.
I would normally budget 30ma for bright 3mm LEDs - so 30x2x13 > 0.8amp
Any advice (before I change my design) would be very welcome.
