Hello friends, I hope you all are doing great. Today, I am going to share the STM32 Black Pill Library for Proteus . The Black Pill from WeAct Studio is the favourite cheap STM32 board: an STM32F411CEU6 - an ARM Cortex-M4 with a floating-point unit at 100 MHz, 512 KB of flash and 128 KB of RAM - on a 53 x 21 mm board with USB-C and 40 pins that fits a breadboard. With this library it runs your STM32 Arduino sketch in Proteus 8.5, with the STM32 core's pin names.
