20 / 42 page  Hardware and layout UM1472 20/42 DocID022256 Rev 4 4.11 Solder bridges Table 4. Solder bridges Bridge State(1) Description SB13,14 (X2 crystal)(2) OFF X2, C14, C15, R24 and R25 provide a clock. PH0, PH1 are disconnected from P2. ON PH0, PH1 are connected to P2 (R24, R25 and R68 must not be fitted). SB3,5,7,9 (Default) ON Reserved, do not modify. SB2,4,6,8 (Reserved) OFF Reserved, do not modify. SB15,16 (X3 crystal) OFF X3, C16, C27, R21 and R22 deliver a 32 KHz clock. PC14, PC15 are not connected to P2. ON PC14, PC15 are only connected to P2. Remove only R21, R22 SB1 (B2-RESET) ON B2 pushbutton is connected to the NRST pin of the STM32F407VGT6 MCU. OFF B2 pushbutton is not connected the NRST pin of the STM32F407VGT6 MCU. SB20 (B1-USER) ON B1 pushbutton is connected to PA0. OFF B1 pushbutton is not connected to PA0. SB17 (VDD powered from 3V) OFF VDD is not powered from 3V, depends on JP1 jumper. ON VDD is permanently powered from 3V, JP1 jumper has no effect. SB11 (NRST) ON NRST signal of the CN2 connector is connected to the NRST pin of the STM32F407VGT6 MCU. OFF NRST signal of the CN2 connector is not connected to the NRST pin of the STM32F407VGT6 MCU. SB12 (SWO) ON SWO signal of the CN2 connector is connected to PB3. OFF SWO signal is not connected. SB10 (STM_RST) OFF No incidence on STM32F103C8T6 (ST-LINK/V2) NRST signal. ON STM32F103C8T6 (ST-LINK/V2) NRST signal is connected to GND. SB18 (BOOT0) ON BOOT0 signal of the STM32F407VGT6 MCU is held low through a 510 ohm pull-down resistor. OFF BOOT0 signal of the STM32F407VGT6 MCU is held high through a 10 Kohm pull-up resistor. SB19 (BOOT1) OFF The BOOT1 signal of the STM32F407VGT6 MCU is held high through a 10 Kohm pull-up resistor. ON The BOOT1 signal of the STM32F407VGT6 MCU is held low through a 510 ohm pull-down resistor. 1. Default SBx state is shown in bold. 2. SB13 and SB14 are OFF to allow the user to choose between MCO and X2 crystal for clock source. |
