    Adapt PCB from Eagle to KiCAD and increase performance from current 80A to 200A with peaks of 400A (specify heatsink for the design). Theoretically, used MOSFETs (FDMT80080DC, two in parallel) should be capable to handle 200A requested currents if they are cooled properly, but heatsink must be calculated. Also the Würth press-fit elements are already capable to handle 200A in theory. Probabl...

    Our current PCB is designed to control four strings of addressable Leds over WiFi using a NodeMCU ESP8266 V2. Works well, but could be better with a few changes. --- Revisions --- - It uses a logic level shifter to connect the 3.3 V ESP data ports to 5 V Leds. We found that there are two sizes of shifters and it is difficult to know what you will get when ordering. A second set of pin holes 2.54...
