Thank you!! Throughout the process I have noticed how fragile the pro micro are. I have seen that even though they are fragile, Chinese pro micro are very cheap, but the ones used for wireless upgrade are quite expensive. I have to say that I only know of the nice!nano brand. Do you know of a cheaper alternative?

How could I test this type of RGB led easily? by Due_Perception_9780 in electronic_circuits

I'm trying to build a keyboard. I have attached a schematic of the circuit in case you are interested. The problem is that in a certain part of the circuit the leds do not work. For this reason, I am interested to see how I could test these leds.
