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.

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.
