Analog Inputs
Terminal block J1 provides four electrostatic discharge (ESD) protected analog inputs
(T_ADC0-T_ADC3) connected to the corresponding ADC0-ADC3 channels of the microcontroller.
Refer to the MDL-IDM-L35 data sheet for electrical limits for these inputs.
Digital I/O
Terminal block J2 provides four ESD-protected digital I/O signals connected to port A (PA2-PA5) of
the microcontroller. These can be used to implement an SSI port or for I/O signals as required.
Refer to the MDL-IDM-L35 data sheet for electrical specifications on these signals.
Headers J4 and J5 provide 12 additional digital I/O lines directly connected to the microcontroller.
Header J4 provides 8 digital I/O lines connected to port G (PG0-PG7) with PG0 and PG1 allocated
for UART2, and header J5 provides 4 digital I/O lines connected to PA6, PA7, PD0, and PD1. Note
that these signals do not have external ESD protection.
Serial Header
Header J8 is for use with the USB to TTL serial cable, and has connections to UART0 (PA0, PA1)
and board power (5 V, GND). This provides a convenient way to power the board and provide a
serial connection to update the board firmware.
