I/O pins are 5V tolerant To switch between SPI and I²C mode, you need to bridge / unbridge the solder jumper at the back (default is SPI) I've tried to make the pinout as compatible as possible to ...
This circuit uses a STM32F103C8T6 MCU, DS18S20 One Wire temp sensor, 16x2 LCD connected in 4-bit parallel mode and an ARCTIC P12 PWM fan. Sensor reads temp, displays it on the LCD. There is a ...
Abstract: The disposal of waste electrical and electronic equipment (WEEE) presents a sustainability challenge, particularly for waste printed circuit boards (PCBs). PCBs are challenging to sort out ...
