On-Board (OB) interface for debugging and programming of the
S1JA MCU. A 10-pin JTAG/SWD interface is also provided for connecting optional external
debuggers and programmers.
Two PMOD connectors, allowing use of appropriate PMOD compliant peripheral plug-in modules for
rapid prototyping
Pin headers for access to power and signals for the Main MCU
•
Multiple clock sources
Main MCU oscillator crystals, providing precision 12.000 MHz and 32,768 Hz reference clocks
Additional low-precision clocks are available internal to the Main MCU
•
MCU reset push-button switch
•
MCU boot configuration jumper
•
General purpose I/O ports
One jumper to allow measuring of Main MCU current
Copper jumpers on PCB bottom side for configuration and access to selected MCU signals
•
Operating voltage
External 5V input through the Debug USB connector supplies the on-board power regulator, which
provides 3.3V to power the Target Board logic and interfaces. External 5V or 3.3V may be also
supplied through alternate locations on the Target Board.
•
A two-color board status LED indicating availability of regulated power and connection status of the J-Link
interface
•
A red User LED, controlled by the Main MCU firmware
•
A User Push-Button switch, User Capacitive Touch Button sensor, and an optional User Potentiometer,
all of which are controlled by the Main MCU firmware
