Pin detailed specifications
Power circuit
Function
The powering circuit provides power to the controller's logic. The KEY input is internally connected with the battery plus terminal via an internal fuse (if selected). Power to the internal SMPS is controlled by an electronic switch which is commanded through the POWER input.
Due to the flip-flop feature (if selected), the powering circuit has a latching functionality and it is not needed to keep the voltage applied on the power circuit. The controller is turned ON if the voltage on the POWER pin is higher than 10 V and turned off once the voltage is below 1 V. The flip-flop also enables turning off the controller from the MCU (automatic power off).
The powering circuit has several modifiable soldered jumpers (needs to be specified during ordering - not possible to modify it after the manufacturing process) which can modify its functionality (see)

General purpose analog/digital inputs
Function
These five inputs can be used for processing analogue and digital voltage levels in the range from 0 - 10 V. These inputs are galvanically isolated from the Power GND, motor sensor GND and external UART GND. The controller offers two isolated power sources. One with an output voltage of +5 V and the second with +10 V. These can be used as a power source for the external components (e.g. throttle). Pull-up and pull-down resistors on all five inputs can be set individually by an FW parameter.
