3 Programming and debugging
For programming and debugging, the X-NUCLEO-USBPDM1 expansion board must be powered by the STM32
Nucleo development board.
JP2 LDO OUT – 3.3 V and 3.3 V – NRST pins must be removed.
TCPP01-M12 can be powered by one of the following options:
• the STM32 Nucleo 3.3 V (JP2 Vcc – 3.3 V jumper close and VCC – V_OUT jumper open)
• a dedicated STM32 GPIO for battery powered cases (JP2 VCC – 3.3V jumper open and VCC – V_OUT
jumper closed). This case is also called low power mode.
TCPP01-M12 dead battery resistor clamps are removed:
• automatically when 3.3 V is present (JP2 DB – 3.3 V jumper closed and DB – DB_OUT open)
• or by a GPIO (JP2 DB – 3.3 V jumper open and DB – DB_OUT closed)
