STM32WL Nucleo-64 board (MB1389)
Introduction
The NUCLEO-WL55JC STM32WL Nucleo-64 board, based on the MB1389 reference board (NUCLEO-WL55JC1 and
NUCLEO-WL55JC2 order codes), provides an affordable and flexible way for users to try out new concepts and build prototypes
with the STM32WL Series microcontroller, choosing from the various combinations of performance, power consumption, and
features.
®
The ARDUINO
Uno V3 connectivity support and the ST morpho headers provide an easy means of expanding the functionality
of the STM32WL Nucleo open development platform with a wide choice of specialized shields.
The STM32WL Nucleo-64 board does not require any separate probe as it integrates the STLINK-V3E debugger and
programmer.
The STM32WL Nucleo-64 board is provided with the STM32WL comprehensive software HAL library and various packaged
software examples available with the STM32CubeWL MCU Package.

If an overcurrent higher than 500 mA occurs on board, the LED4 red LED is lit. The Nucleo board and its shield can be powered from ST-LINK USB connector CN1, but only the ST-LINK circuit gets power before USB enumeration, because the host PC only provides 100 mA to the board at that time. -

Page 24: Debugging While Using Vin Or Ext As An External Power Supply
Debugging while using VIN or EXT as an external power supply When powered by VIN or E5V, it is still possible to use the ST-LINK for programming or debugging, but it is mandatory to power the board first using VIN or EXT, then to connect the USB cable to the PC. In this way, the enumeration succeeds, thanks to the external power source. -
