+
+Hardware
+--------
+The hardware is relatively easy to assemble. Just follow the schematic and don't forget to [cut the VBUS jumper](https://www.pjrc.com/teensy/td_libs_USBHostShield_4a.jpg).

+Schematic:
+![Schematic](https://i.imgur.com/s1Ia9We.png)
+
+Part list:
+* [Adafruit Feather 32u4 Bluefruit LE](https://www.adafruit.com/product/2829)
+* [USB Host Mini](https://www.circuitsathome.com/arduino_usb_host_shield_projects/)
+* [Pololu 5V Step-Up Voltage Regulator U3V12F5](https://www.pololu.com/product/2115)
+* [Lithium Ion Battery - 3.7v 2000mAh](https://www.adafruit.com/product/2011)
+* Some sort of switch to be able to turn it off
