 The [schematic](/hardware/schematic/) shows the architecture of the power supply.
 Key points to note are that there are two BAT60A diodes, one from the 3.3V supply from the KL26/27 interface chip, and one from the external battery connector.
-Note that the 3V ring on the edge connector is V_TGT, which is the raw supply provided to all on-board chips, so this is why extra care should be taken when connecting directly to the 3V ring or the 3V lozenge.
