Hardware and layout 4 UM1658 Hardware and layout The STM32F030 Value Line Discovery board is designed around the STM32F030R8T6 microcontroller in a 64-pin LQFP package. Figure 2 illustrates the connections between the STM32F030R8T6 and its peripherals (ST-LINK/V2, push button, LEDs and connectors). Figure 3 and Figure 4 help you to locate these features on the STM32F030 Value Line Discovery board. Figure 2.

UM1658 4.2 Hardware and layout Embedded ST-LINK/V2 The ST-LINK/V2 programming and debugging tool is integrated on the 32F0308DISCOVERY. The embedded ST-LINK/V2 can be used in 2 different ways according to the jumper states (see Table 2): • Program/debug the MCU on board, • Program/debug an MCU in an external application board using a cable connected to SWD connector CN3. The embedded ST-LINK/V2 supports only SWD for STM32 devices.
Hardware and layout 4.2.1 UM1658 Using ST-LINK/V2 to program/debug the STM32 F0 on board To program the STM32 F0 on board, simply plug in the two jumpers on CN2, as shown in Figure 8 in red, but do not use the CN3 connector as that could disturb communication with the STM32F030R8T6 of the 32F0308DISCOVERY. Figure 8.
UM1658 4.2.2 Hardware and layout Using ST-LINK/V2 to program/debug an external STM32 application It is very easy to use the ST-LINK/V2 to program the STM32 on an external application. Simply remove the 2 jumpers from CN2 as shown in Figure 9, and connect your application to the CN3 debug connector according to Table 3. Note: SB19 and SB22 must be OFF if you use CN3 pin 5 in your external application. Table 3.
Hardware and layout 4.3 UM1658 Power supply and power selection The power supply is provided either by the host PC through the USB cable, or by an external 5 V power supply. The D1 and D2 diodes protect the 5 V and 3 V pins from external power supplies: 4.4 4.5 4.6 • 5 V and 3 V can be used as output power supplies when another application board is connected to pins P1 and P2. In this case, the 5 V and 3 V pins deliver a 5 V or 3 V power supply and power consumption must be lower than 100 mA.
UM1658 Hardware and layout 4.7 OSC clock 4.7.1 OSC clock supply PF0 and PF1 can be used as GPIO or as HSE oscillator. By default these I/Os are configured as GPIO, so SB16 and SB17 are closed, SB18 is open and R22, R23, C13 and C14 are not populated. An external HSE clock can be provided to the MCU in three ways: • • • 4.7.2 MCO from ST-LINK. From MCO of the STM32F103. This frequency cannot be changed, it is fixed at 8 MHz and connected to PF0-OSC_IN of the STM32F030R8T6.
Hardware and layout 4.8 UM1658 Solder bridges Table 4. Solder bridge settings Bridge State(1) Description OFF X2, C13, C14, R22 and R23 provide a clock. PF0, PF1 are disconnected from P1. ON PF0, PF1 are connected to P1 (R22, R23 and SB18 must not be fitted). SB6,8,10,12 (Default) ON Reserved, do not modify. SB5,7,9,11 (Reserved) OFF Reserved, do not modify. SB20,21 (X3 crystal) OFF X3, C15, C16, R24 and R25 deliver a 32 KHz clock. PC14, PC15 are not connected to P1.
UM1658 4.9 Hardware and layout Extension connectors The male headers P1 and P2 can connect the 32F0308DISCOVERY to a standard prototyping/wrapping board. STM32F030R8T6 GPI/Os are available on these connectors. P1 and P2 can also be probed by an oscilloscope, logical analyzer or voltmeter. Table 5.
