STM32_LED_12x10W_Mosfet_Controller - 5V mosfet gate

Stm32 F103 C8/CB - 12x 10W LED PWM controller based on MOSFET with current sense resistor. Traditional and simple design; Designed 12V PC PSU.
Module supports attachment of ESP8246 WiFi module and 1.3inch OLED display HAT for Raspbery pi: https://www.waveshare.com/1.3inch-oled-hat.htm.
Two additional I2C connection are possible on I2C2 and 2x 5V 3pin 140mA PWM driven FAN connections.
Module utilises built in RTC with VBAT connected to 1F Supercap (Panasonic EECS5R5H105).
Programming can be achieved by USB bootloader, design mirrors BlackPill diode on PB12.

Aim of the project is to provide cheap and sustainable LED lighting for Marine aquarium. With 12x 0.5A channels board can drive 3x3W LED per channel.
