 In addition to a "Blue Pill," you will need a **3.3V USB to serial converter**. I used a [[https://www.sparkfun.com/products/14050|SparkFun Serial Basic]] configured for 3.3V. Only the TX and RX pins and, optionally, power will be used, so you should be able to use a standard FTDI board as well.

+=== Mind the voltages! ===
 Some serial converter boards put out 5V as VCC even when set to 3.3V mode. Applying 5V to the 3.3V main supply line of a Blue Pill will kill it.

 There is a 5V input on the Blue Pill and a USB connector that can power the board from 5V. These go through a small 3.3V regulator.

+=== Connections ===
   * Connect ground from the serial converter board to the ''GND'' pins of the Blue Pill.
   * Connect the serial converter's RX to the Blue Pill's ''A9''.
   * Connect the serial converter's TX to the Blue Pill's ''A10''.
-  * If you will be powering the Blue Pill from the serial converter board, connect VCC from the serial converter board to the ''3.3'' pin of the Blue Pill (or ''5V'' if your serial converter board puts out 5V even in 3.3V mode).
