6 Recommendations
6.1 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.
• PH3_BOOT0 must be tied low to enable start from flash memory.
• 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).
