7.2 Discovery board: STM32F072B-DISCO
The STM32F072 Discovery kit helps the user to discover the STM32F072, which has the full set of features
available in the STM32F0 Series, and to develop his applications easily. It includes everything required for
beginners and experienced users to get started quickly.
Based on the STM32F072RBT6, it includes an ST-LINK/V2 embedded debug tool interface, an ST MEMS
gyroscope, LEDs, push-buttons, linear touch sensor, RF EEPROM connector and a USB mini-B connector.
This discovery board provide a three channels linear (or slider) sensor. the main characteristics of these sensor
are:
• On-board ST-LINK/V2
• Supply through ST-Link USB
• External Supply: 3V and 5V
• JP2 (Idd) for current measurement
• Full-Speed USB with mini-B Connector
• Motion sensor, 3-axis digital output gyroscope (L3GD20)
• One Linear Touch Sensor or four Touch Keys
• Two Push-buttons: User and Reset
• Six LEDs: USB COM, 3.3 V Power, User (Orange/Green/Red/Blue)
• Extension header: (2 x 33) with 2.54 mm Pitch
• Discovery Board Formfactor
