USART,The Blue Pill PCB provides one GPIO-controlled LED to communicate by. Needless to say, this would be limiting if it were all you had. Perhaps the best early-development peripheral to pursue for communication is the USART (Universal Synchronous/Asynchronous Receiver/Transmitter).

USB Serial,One of the nice things about the STM32 MCU is the availability of the USB (Universal Serial Bus) peripheral. With USB, it is possible to communicate directly with a desktop platform in various modes. One of these flexible modes is USB’s emulation of a serial link between the MCU and the desktop.

SPI Flash,As resourceful as the STM32 MCU is, sometimes you need additional persistent data storage. Small applications may leave leftover program flash storage that can be utilized, but if you are collecting larger amounts of data, you will probably look to a serial flash solution.

Real-Time Clock (RTC),Tracking time is often important in applications. For this reason, the STM32 platform provides a built-in real-time clock (RTC) peripheral. The datasheets for the RTC appear almost trivial to use, but there are wrinkles waiting for the unwary.

OLED,The OLED (organic light-emitting diode) provides the hobbyist with an exciting form of low-cost display. Because they are based upon LEDs, they require no backlighting like an LCD device does, nor polarizing filters. This equates to lower cost.

Analog-to-Digital Conversion,Embedded computing often needs to convert an analog signal level into a digital form for analysis. One application is measuring temperature by the voltage developed across a semiconductor. It is no surprise then that the STM32 platform has both an analog-to-digital converter (ADC) and a built-in channel to the ADC for measuring temperature.

Clock Tree,Until this point, there’s been an elephant in the room. We’ve configured and used various clocks without saying too much about them. Now is a good time to reveal some of the clock components that have been lurking in the shadows.
