 ====== Hardware overview ======
+===== Motherboard revisions =====
+There are atleast two known revisions of the WiiU gamepad motherboard.
+**Revision 01** (PWB/MAIN/AU/HF-C/DH-01) is the most common.
+**Revision 20** (DRC-MAIN-20) is possibly an earlier motherboard revision. The most notable difference is that the speakers are soldered directly to the motherboard instead of using connectors. There are also other minor hardware differences, the full extent of which isn't known yet.
+A motherboard's revision can be read near the battery connector. It is visible even in a fully assembled gamepad.
