Pin Description
RSSI Output
The RSSI provides a DC Voltage proportional to the peak value of the receive data signal. This output can be
used as an indicator for the received signal strength to use in wake-up circuits etc.
An RC circuit is normally used to provide the timing for the RSSI signal. The modules have a 10nF capacitor
internally connected to GND, therefore a pull down resistor (to GND) connected to the RSSI pin may be used to
generate a simple RC network time constant for the RSSI signal output.
Please note that the maximum output current is typically 950µA, the discharge current is lower than 2µA
