Description
Description
A ESP-12 IoT controller for RGB LED Stripe 5-12V.
3+1 channels through MOSFET, PWM and dimming functionality.
The MOSFETs can be replaced by NPN Power transistors (input resistors are as THT parts placed, the 10k pull down's not needed.
The 4th channel is a Logic level up-converter (3.3V->5V). Driven by a 2N7002, can be replaced with BSS138 or similar. Note that it's is a very small power output (115mA) and not useable to drive lot of Neopixels. But ready for 8-bit WS2812 lines/rings.
