3.10 DC-power and Battery Power

RB5 power is supplied in one of the following ways:
8 V to 18 V power from a dedicated DC jack

8 V to 18 V power from the DC12V pins on the low-speed expansion connector

See Section 6 for details on Robotics RB5 Development Kit DC power implementation.

3.11 DC power Measurements

The 96Boards specification calls for support for measuring board power consumption.
See Section 6 for details on Robotics RB5 Development Kit DC power measurement.

3.12 Buttons

The 96Boards specification calls for the presence of two buttons, a power on/sleep button
and a reset button. RB5 meets these requirements.
See Section 7 for details on RB5 buttons.

3.13 External Fan connection

The 96Boards specification calls for support of an external fan. There is a on-board fan
connector on main IO(see section 1.2.2, #25), fan power is 12V.

3.14 UART

RB5 supports one 4bit UART, and a 2bit UART (optional), and both of them are routed to
the low-speed expansion connector.
The 4bit UART comes directly from SoC pins to low-speed expansion connector. The 2bit
UART is optional an on-board UART debug log port via Micro USB port#21, or to be
routed to low-speed expansion connector. To use the port for log output, switch
DIP_DEBUG_UART_SWITCH on DIP switch (section 1.2.2#16) to ON.

3.15 JTAG (NA)

NA

3.16 System and user LEDs

RB5 supports seven LEDs on the board. LEDs color and mechanical location on the board
are designed based on 96Boards specification.
Two activity LEDs
