And to complement the hydraulic valve driver board here we also have a joystick interface board.
A lot of it is the same as in the valve driver board like RS-232 and CAN interfaces, just the analog section has been changed for accepting input from joysticks and scaling the input signal to be suitable for the AD converter of the STR7 microcontroller. This board supports 4 analog input channels for the joystick axes and 12 digital channels for switches. There are also additional 8 general purpose IO pins in a separate header. These 8 IO pins can be also configured as two separate hardware SPI channels.
