The STM32 Nucleo boards offer the following features:
• STM32 microcontroller with LQFP64 package 
• Two types of extension resources

– Arduino Uno Revision 3 connectivity
– STMicroelectronics Morpho extension pin headers for full access to all STM32 I/Os 

• mbed-enabled

(a)

• On-board ST-LINK/V2-1 debugger/programmer with SWD connector

– selection-mode switch to use the kit as a standalone ST-LINK/V2-1

• Flexible board power supply

–

USB VBUS

–

External VIN (7V<VIN<12V) supply voltage from Arduino connectors or ST 
Morpho connector

–

External 5V (E5V) supply voltage from ST Morpho connector
