I got some signal MOSFETs for smaller level shifting between a 3.3V microcontroller and the 5V WS2812 LEDs. In the middle is a 2N7000 in TO-92 package (good for through hole soldering) and on the right side the BSS138 (only available as SOT-23, so I needed an adapter for breadboard testing). For comparison a quite chunky standard logic level shifter/converter (4 lines plus power/ground). Both types work like a charm. So it's time to create a new revision of my PCB for the coffee notification button. Yay! #mosfet #bss138 #2n7000 #logic #levelshifter #converter #microcontroller #mcu #esp01 #esp8266 #esp8285 #arduino #ws2812b #led #lights #control #electronics #tinkering #soldering #hardwareporn #embedded #hardware #iot #tiny #hobby (hier: Lichtenberg, Berlin, Germany) https://www.instagram.com/p/BuhTTQCh9LN/?utm_source=ig_tumblr_share&igshid=5kiy4xm3x349
