4.1 UART {0/1}
The 96Boards specifications calls for a 4-wire UART implementation, UART0 and an optimal second 2-wire UART, UART1 on
the Low Speed Expansion Connector.
The DB4 IOT implements UART0 as a 4-wire UART that connects directly to the APQ8016 SoC. These signals are driven
at 1.8V.
The DB4 IOT implements UART1 as a 2-wire UART that connects directly to the APQ8016 SoC. These signals are driven
at 1.8V.
4.2 I2C {0/1}
The 96Boards specification calls for two I2C interfaces to be implemented on the Low Speed Expansion Connector.
The DB4 IOT implements both interfaces, I2C0 and I2C1 that connects directly to the APQ8016SoC. A 2K resistor is
provided as pull-up for each of the I2C lines per the I2C specifications, these pull-ups are connected to the 1.8V voltage
rail.
4.3 GPIO {A-L}
The 96Boards specifications calls for 12 GPIO lines to be implemented on the Low Speed Expansion Connector. Some of
these GPIOs may support alternate functions for DSI/CSI control
The DB4 IOT implements this requirement. 11 GPIOs are routed to the APQ8016 SoC and one GPIO is connected to the
on-board PMIC.
•GPIO A - Connects to GPIO_36 of APQ8016 SoC, can serves as AQP_INT supporting the 96Boards requirements to
create a wake-up event for the SoC. It is a 1.8V signal
•GPIO B - Connects to GPIO_12 of APQ8016 SoC. It is a 1.8V signal

•GPIO L - Connects to GPIO_33 of APQ8016 SoC. It is a 1.8V signal. Can be configured to be a CSI1_PWDN signal.
4.4 SPI 0
The 96Boards specification calls for one SPI bus master to be provided on the Low Speed Expansion Connector.
The DB4 IOT implements a full SPI master with 4 wires, CLK, CS, MOSI and MISO all connect directly to the APQ8016
SoC. These signals are driven at 1.8V.
4.5 PCM/I2S
The 96Boards specification calls for one PCM/I2S bus to be provided on the Low Speed Expansion Connector. The CLK, FS
and DO signals are required while the DI is optional.
The DB4 IOT implements a PCM/I2S with 3 wires, CLK, FS and DO, the optional DI signal is not implemented on the DB4 IOT

4.6 Power and Reset
The 96Boards specification calls for a signal on the Low Speed Expansion Connector that can power on/off the board and a
signal that serves as a board reset signal.
The DB4 IOT routes the PWR_BTN_N (named PHONE_ON_N on DB4 IOT schematic) signal to the KYPDPWR_N pin of the
PM8916 PMIC. This signal is driven by S2 as well, the on-board power on push-button switch. Please note that the push
button only provides an On/Sleep function and not OFF functionality.
A mezzanine implementation of this signals should not drive it with any voltage, the only allowed operation is to force it to
GND to start the board from a sleep mode. A board shutdown will occur when this signal is held to ground for more than
15 seconds (based on the current Android release).
The DB4 IOT routes the RST_BTN_N (named PM_RESIN_N on DB4 IOT schematic) signal to the RESIN_N pin of the PM8916
PMIC. This signal is driven by S4, the on-board reset switch. This signals is a dual purpose, any press lasting less than 10 seconds
serves as Volume Down or Zoom out, a press longer than 10 seconds will reset the board.
4.7 Power Supplies
The 96Boards specification calls for three power rails to be present on the Low Speed Expansion Connector:
•+1.8V : Max of 100mA
•+5V : Able to provide a minimum of 5W of power (1A).
•SYS_DCIN : 9-18V input with enough current to support all the board functions or the output DCIN from on-
board DC Connector able to provide a minimum of 7W of power.
The DB4 IOT supports these requirements as follows:
+1.8V : Driven by two PMIC LDOs, LDO15 and LDO16, each can provide 55mA. The PM8916 allows connecting the two
LDOs in parallel to provide 110mA on a 1.8V rail which meets the 96Boards requirement.
+5V : Driven by the 4A 5.0V buck switcher (U13). This buck switcher powers both USB limit current devices (each at
1.18A max). The remaining capacity provides a max current of 1.64A to the Low Speed Expansion Connector, for a total of
8.2W which meets the 96Boards requirements.
SYS_DCIN: Can serves as the board’s main power source or can receive power from the board.
