Packet detect output. Signal switches logic high at the end of the start-of-packet symbol and switches logic
low at the end of the end-of-packet symbol on both received and transmitted packets. PKT_DET provides a
timing reference for external use in network timing evaluations, etc.
Reserved pin. Leave unconnected.
ADC supply and external full scale reference voltage input. Voltage range is 2.4 to 3.3 Vdc. Connect pad 34 to
this input to reference the ADC full scale reading to the module’s 3.3 V regulated supply.
Reserved pin. Leave unconnected.
Configurable digital I/O port 0. When configured as an input, an internal pull-up resistor can be selected and
interrupt from sleep can be invoked. When configured as an output, the power-on state is also configurable.
Configurable digital I/O port 1. Same configuration options as GPIO0.
Configurable digital I/O port 2. Same configuration options as GPIO0.
Configurable digital I/O port 3. Same configuration options as GPIO0.
8-bit pulse-width modulated output 0 with internal low-pass filter. Filter is first-order, with a159 Hz 3 dB
bandwidth.
8-bit pulse-width modulated output 1 with internal low-pass filter. Filter is first-order, with a 159 Hz 3 dB
bandwidth.
Active high module sleep input (active low DTR). When switched low after sleep, the module executes a
power on-reset. Usually connected to host DTR. Connect to ground if SLEEP/DTR function not used.
10-bit ADC input 0. Full scale reading is referenced to the ADC_REF input.
10-bit ADC input 1. Full scale reading is referenced to the ADC_REF input.
10-bit ADC input 2. Full scale reading is referenced to the ADC_REF input.
Rising-edge triggered input for synchronizing co-located base stations. Synchronization pulse interval must
equal hop dwell time ±10 µs. Pulse width must be in the range of 50 µs to 2 ms.
Diagnostic UART transmitter output.
Diagnostic UART receiver input.
Protocol selection input. Leave unconnected when using software commands to select transparent/protocol
mode (default is transparent mode). Logic low selects protocol mode, logic high selects transparent mode.
Power supply input, +3.3 to +5.5 Vdc.
Power supply and signal ground. Connect to the host circuit board ground.
Power supply and signal ground. Connect to the host circuit board ground.
Configurable digital I/O port 4. When configured as an input, an internal pull-up resistor can be selected.
When configured as an output, the power-on state is configurable.
Configurable digital I/O port 5. Same configuration options as GPIO4.
Logic ground.
Data activity output, logic high when data is being transmitted or received.
Default functionality is data carrier detect output, logic low on a remote when the module is locked to FHSS
hopping pattern and logic low on a base station when at least one remote is connected to it.
