=Checklist=
* only set jumper JP1 (9V power) after you have manually set and measured the correct voltage (9v) at DC/DC Vout pin
* set jumper JP13 on PCB back side for a Marotronics Arduino Due (i.e. Due clone) for automatic reset
* set jumper JP12 (GPS signal voltage) to 3.3VP for Marotronics GPS module
* set jumper JP7 (GPS operating voltage) to 5VP for Marotronics GPS module
* set jumper JP10 (Bluetooth signal voltage) to 3.3VP for Marotronics Bluetooth module
* set jumper JP4 (Bluetooth operating voltage) to 5V for Marotronics Bluetooth module
* set jumper JP6 (WIFI operating voltage) to 3.3V for Marotronics WIFI module
* set jumper JP11 (WIFI signal voltage) to 3.3V for Marotronics WIFI module
* set jumper JC2 (IMU signal voltage) to 3.3V for Marotronics IMU module
* only set I2C jumpers JC2, JC3, JC4, JC5, JC6, JC7 (at the top) if there is a corresponding I2C module installed
* set jumper JP8 to 'Always-ON' for tests and for Arduino uploads, for regular operation (and automatic undervoltage power-off) to 'Automatic'
* unset jumper JP3 (2nd mower motor MC33926 M1FB), not used
* Solder a bridge on leftmost pins of S1 ODO right and S2 ODO left (PCB back side)
* RTC module must be installed for proper I2C bus operation
* press button P20 to power-on PCB

=Assembly=

==Soldering the mainboard components==

The assembly of the board is tricky as some components have been packed tightly - especially those below the motor drivers.

The following table lists each component to be placed by hand along with other components that might collide. Collisions marked with a '?' are hard (but still possible) to solder if the components are not placed in the right order. Those without a '?' are impossible. The table has been sorted to provide a practical order for soldering: low components come first and components blocking each other are in the right order. Similar components and spatiality has been used to form groups.
