Pin recommendations

•

ANT_IN and RF_OUT pins must be connected to GND. This module already integrates an antenna, so no

external antenna required.

•

The ANT_NC is only used for soldering planarity purposes. So this pin must be soldered to an unconnected

pin on the customer board.

•

A reset pull-up is already implemented in the STM32WB Series microcontrollers. The reset circuitry only

requires an external capacitor for filtering purpose (see Figure 3).
