User Manual

*Pins PA6 and PA7 on the Orangutan X2 are connected by default through SMT jumpers to the a battery
voltage divider circuit and the user trimpot, respectively. You should not make external connections to these
pins without first breaking the default SMT jumper connections, which are located on the underside of the main
board and labeled in the silkscreen “ADC6=BATLEV” and “ADC7=TRIMPOT”.
