 ## What you need

In this example we will be using the [Jeff Probe](https://flirc.tv/products/flirc-jeffprobe?variant=43085036585192) with the portapack H2+ in an aluminium case.
+  * Or something similar (bluepill (STM32F103C8T6) works as well, just add `BLUEPILL=1` when you compiling the blackmagic).
