1. Prepare by ensuring you have Tera Term installed on your computer, and that your PiBoy is updated to the latest firmware (1.05 or higher).
2. Remove both the micro SD card and the Raspberry Pi from the PiBoy. The Raspberry Pi is removed by undoing the 6 case screws, as well as the 4 screws attaching the hat to the bracket. Gently remove the hat from the Pi, being careful not to damage the ribbon cable, and carefully remove the Pi from the brackets, taking the SD connector out from the micro SD slot on the Pi.
3. Connect the PiBoy to your computer using a micro USB cable.
4. Open Tera Term, select serial and press Ok.
