Page 14: Power Supply
Power supply The STM32WBA65I-DK1 Discovery kit IoT node board is designed to be powered by a 5 V DC power supply. It is possible to configure the Discovery board using a jumper on JP4 to use any of the following five sources for the power supply: 5V_USB_STLK, 5V_VIN, 5V_EXT, 5V_USB_CHGR, and 5V_USB_MCU. -
Page 15: 5V_Vin
UM3462 Hardware layout and configuration 7.2.2 5V_VIN ® ® 5V_VIN is the 7 to 12 V DC power from the ARDUINO connector (CN9 pin 8) named VIN on the ARDUINO ® connector silkscreen (the extension connectors for ARDUINO Uno shields or daughterboards). In this case, a jumper must be set on [3‑4] to select the 5V_VIN power source on the JP4 silkscreen (refer to Figure 10 below). -

If the board is powered by a USB charger, there is no USB enumeration, so the red LED (LD2) remains OFF permanently. Caution: Be aware that, if you connect a PC to the ST-LINK connector (CN6), the PC is not protected. The green LED (LD1) is lit when 5V correctly powers the STM32WBA65I-DK1 Discovery board.

Page 18: Current Measurement
UM3462 Hardware layout and configuration 7.2.6 Current measurement The device has low-power features. It can be interesting to measure the current consumed by the STM32WBA65RI on the discovery board. To do this measurement easily, there are two possibilities: 1. Measure the supply current of the SoC using an ammeter in place of the jumper (JP2). Refer to Figure 15 below. -
Page 19: Figure 16. Current Measurement With An External Power Supply
UM3462 Hardware layout and configuration 2. Use an external power supply with current measurement capability. In this case, the jumper (JP2) must be OFF and the supply must be connected to pin 1 of JP2 (refer to Figure 16). The supply voltage must be between 1.8 and 3.3 V. -
Page 20: Figure 17. Current Measurement With Stlink-V3Pwr
UM3462 Hardware layout and configuration 3. If it is necessary to do power consumption measurement during debugging, STMicroelectronics has an interesting solution. It is possible to use an STLINK-V3PWR. This product allows two sources of supply: a first for the current measurement on the STM32WBA65RI, and a second source to supply the rest of the board (LEDs). -
