The D1 and D2 diodes protect the 5V and 3V pins from external power supplies: 4.4 4.5 4.6 ● 5V and 3V can be used as output power supplies when another application board is connected to pins P1 and P2. In this case, the 5V and 3V pins deliver a 5V or 3V power supply and power consumption must be lower than 100 mA. ● 5V can also be used as input power supplies e.g. when the USB connector is not connected to the PC. In this case, the STM32F0DISCOVERY board must be powered by a power supply unit or by auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability. LEDs ● LD1 PWR: Red LED indicates that the board is powered. ● LD2 COM: Tricolor LED (COM) advises on the communication status as follows: – Slow blinking Red LED/Off: At power on before USB initialization – Fast blinking Red LED/Off: After the first correct communication between PC and STLINK/V2 (enumeration) – Red LED On: When initialization between PC and ST-LINK/V2 is successfully finished – Green LED On: After successful target communication initialization – Blinking Red/Green LED: During communication with target – Red LED On: Communication finished and OK – Orange LED On: Communication failure ● User LD3: Green user LED connected to the I/O PC9 of the STM32F051R8T6. ● User LD4: Blue user LED connected to the I/O PC8 of the STM32F051R8T6. Push buttons ● B1 USER: User push button connected to the I/O PA0 of the STM32F051R8T6. ● B2 RESET: Push button used to RESET the STM32F051R8T6. JP2 (Idd) Jumper JP2, labeled Idd, allows the consumption of STM32F051R8T6 to be measured by removing the jumper and connecting an ammeter. ● Jumper on: STM32F051R8T6 is powered (default). ● Jumper off: an ammeter must be connected to measure the STM32F051R8T6 current, (if there is no ammeter, the STM32F051R8T6 is not powered).

Software examples, based on the connections described below, are available at www.st.com/stm32f0discovery. 5.1 Mikroelektronica accessory boards Mikroelektronika, http://www.mikroe.com, has specified two standard connectors for their accessory boards, named mikroBUS™ (http://www.mikroe.com/mikrobus_specs.pdf) and IDC10. MikroBUS™ is a 16-pin connector to connect accessory boards very quickly and easily to a microcontroller board through SPI, USART or I2C communications, along with additional pins such as Analog Input, PWM and Interrupt. The set of mikroElektronika boards compatible with mikroBUS™ is called “Click boards”. IDC10 is a 10-pin connector to connect the general purpose I/O of an MCU to other accessory boards. The tables below are one solution for connecting mikroBUS™ and IDC boards to the STM32F0DISCOVERY; this solution used in the different examples is available at www.st.com/stm32f0discovery. Table 7.
