CSI-2 output (J1)
This is a 22 pin 4 lane CSI-2 connector with 0.5mm pitch (Wuerth 687122149022). To open the connector and to
release the cable just lift the brown lid upwards. This connector has the same pinout as the CSI-2 connector on
the Raspberry Pi compute module carrier board or the Pi Zero. The contacts are on the bottom. Please use a
FPC cable with contacts on the same side.

MCU
The V20 micro controller (MCU: STM32F042F6P6) with 32 kByte Flash and 6kByte RAM. At this time the MCU is
not used and not programmed. For future expansion only.
MCU pin description
Pin types:
PP - push/pull output"
OD - open drain output"
Ain - analog input"
AF - alternate function
IO - Input/Output
The power supply to the MCU is supplied by a 3.3V LDO regulator which is always on. So the MCU is powered as
soon as power is applied to the power input on J1. This allows the MCU to manage whether power should be
applied to the carrier board.
The MCU tunnels the console UART interface to the Jetson Nano. Some instructions are intercepted by the MCU
and executed by it. These instructions are not forwarded to the compute module.
