STM32F411 Black Pill Development Board V3.1 Gas Sensor Module - MQ5 (Analog/Digital) Female T-Plug on the otherThis Black pill development board from Weact based on the STM32F411 is for more serious users. It adds a powerful STM32 microcontroller to your next project. Featuring the STM32F411CEU6, this chip has 512 KB of flash, 128 KB of SRAM, and runs at 100 MHz. The development board itself has multiple UART, I2C, SPI, I2S, and timer pinout. We recommend pairing with our ST Link programmer and debugger if you want to use a debugger. Thanks to the STM
