5.1 40 way Hirose Pin Descriptions

The Hirose DF12C board-to-board connector on the module is a 40-pin double-row receptacle.

The table below defines the pin functions. The pin-out is as viewed from the underside of the Module.

Notes:

The reset circuitry within the module incorporates a brown-out detector. The reset pin has a fixed

10kOhm pull down resistor to ground, followed by a 10kOhm resistor feeding the base of a transistor.

GPIO lines can be configured through software to be either inputs or outputs. At reset, all GPIO lines

are configured as inputs.

UART_RX, UART_TX, UART_CTS, UART_RTS, UART_RI, UART_DCD, UART_DTR and UART_DSR are all

3.0v level logic. When the signal sits at 3.0V it is de-asserted. When the signal is at 0V it is asserted.

UART_RX, UART_TX, UART_CTS, UART_RTS are controlled directly by the module. The operation of

UART_RI, UART_DCD and UART_DTR is user programmable under script control.

Pin 27 (VCC_3V) may only be used for monitoring purposes. It must not be used as a current source.

Pin 22 (WAKEUP) will be used for future powersave functionality. It has an internal 100kOhm pull-up.

ADC inputs (pins 1 and 3) are read using UWscript functions.

UART_DSR is used to enable autorun. After power-up it can be used as GPIO. See Section 8.2.

Pins marked N/C may have internal connections within the module and should not be connected to any

external circuitry.
