These run the same firmware that is present on many official STMicro development boards, but they can be used to debug just about any ARM microcontroller. Faster and more featureful debuggers are available (in a very wide price range), but this will get you started.
|
||||
|
||||
Fun fact: These debuggers typically have exactly the same microcontroller as the Blue Pill board, so the datasheet and manuals will also apply to it if you want to repurpose it to do something else!

This is an I2C-controlled 2-zone monochrome OLED display (resolution of 128x64) of the sort that was featured on many older mp3 players. The top "menu" section of the screen has yellow pixels, while the rest has blue pixels. It features a SSD1306 display controller with an internal bitmapped display buffer.

This I2C-managed chip contains a 3-axis accelerometer and a 3-axis gyroscope, giving motion tracking capabilities similar to a cell phone or a Wii-mote. Paired with the Blue Pill, this could form the basis of a unique input device for your computer via USB or the brains of a self-balancing robot.

You could potentially disassemble the board and hook the thermistor up to an Analog-to-Digital Conversion (ADC) channel on the Blue Pill to read the actual temperature. You could also replace the thermistor on the board with a photoresistor to actuate the switch based on the amount of light, or repurpose the analog comparator in a different circuit for detecting when voltage thresholds are reached.
