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.
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,
other than those that have dual functionality as modem control signals 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.
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 commands over the UART.
UART_DSR is used to signal the module to enter Power Save Mode 2.
Pins marked N/C may have internal connections within the module and should not be connected to any
external circuitry.
