-## Pinout
+## Summary
+The Clarity PCU is simple. The control board is an Infineon (Cypress) ARM MCU, controlled components (so far identified) are
+
+- QTY16 ROHM BM60051 gate drivers
+- a pre-charge relay
+- some temperature sensors
+- a battery bus current sensor
+
+## Connections
+
+### Control Unit <=> Power Module
+Control -> Power board is QTY1 32-pin cable (probably QTY2 wires per driver), QTY1 12-pin cable.
+
+### Control Unit <=> Outside world
+There's a 30-pin connector wired to the other side of the control board.
 
 ## Cooling
+Almost all the internal space is dry, except for a cooling pipe squashed in the center. I know coolant is one-way, I just don't know which has to be cooler (the copper core or the gates?).
 
+For prototyping, all of the components can be briefly run without coolant.
