ST NUCLEO-WL55JC STM32WL - Hardware layout and configuration

6 Hardware layout and configuration
The STM32WL Nucleo-64 board is designed around the STM32 microcontrollers in a 73-pin UFBGA package.
Figure 3 shows the connections between the STM32 and its peripherals (STLINK-V3E, push-buttons, LEDs, USB,
ARDUINO
®
Uno and ST morpho headers). Figure 4 and Figure 6 show the location of these features on the
STM32WL Nucleo-64 board. The mechanical dimensions of the board are shown in Figure 7.
