Before first use, check the board for any damage that might have occurred during shipment, that all socketed components are firmly fixed in their sockets and that none are loose in the plastic bag. UM2708 - Rev 2 page 6/41...
2) illustrates the ® ™ connection between the STM32 and peripherals: embedded ST-LINK, ARDUINO Uno V3 shields, Pmod connector, Quad-SPI Flash memory, USB OTG connectors, digital microphones, various ST-MEMS sensors, ® ® and the three RF modules (Wi‑Fi , Bluetooth , and NFC).
6.1.2 ST-LINK/V2-1 firmware upgrade The ST-LINK/V2-1 embeds a firmware upgrade mechanism for the in-situ upgrade through the USB port. As the firmware may evolve during the lifetime of the ST-LINK/V2-1 product (for example new functionalities, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com...
Figure This is a 5V DC power with limitation from CN7, the USB type Micro-B connector of ST-LINK/V2-1. In this case, the JP4 jumper must be fitted between pin 1 and pin 2 to select the 5V_ST_LINK power source on the JP4 silkscreen.
This is the DC power coming from an external source. In this case, the JP4 jumper must be fitted between pin 7 and pin 8 to select the 5V_VBAT power source on JP4 silkscreen. UM2708 - Rev 2 page 13/41...
In this specific case only, the resistor R30 must be soldered, to allow the board to be powered anyway. Caution: Do not connect the PC to the ST-LINK (CN7) when R30 is soldered. The PC may be damaged or the board may not be powered correctly. UM2708 - Rev 2...

UM2708 Programming and debugging when the power supply is not from ST-LINK (5V_ST_LINK) Programming and debugging when the power supply is not from ST-LINK (5V_ST_LINK) It is mandatory to power the board first using CN2 (VIN) or CN9 (USB_FS_OTG), then to connect the USB cable to the PC.
Virtual COM port The serial interface USART1 is directly available as a Virtual COM port of the PC connected to the ST-LINK/V2-1 USB connector CN7. The Virtual COM port settings are configured with 115200 bps, 8-bit data, no parity, one-stop bit, and no flow control.
128 blocks of 4 bytes which can be split into four flexible and protectable areas. Note: The hardware layout is ready to support a Sub-GHz low-power-programmable RF module (SPSGRF-868 or SPSGRF-915). The footprint is implemented (M3 designation), but no module is soldered. UM2708 - Rev 2 page 18/41...
• Or IMP34DT05 on MB1297-L4S5VI-E03 revision (BL4S5IIO01A$CU3). These microphones are ultra-compact, low-power, omnidirectional, digital ST-MEMS microphones built with a capacitive sensing element and an IC interface. On the B-L4S5I-IOT01A Discovery kit for the IoT node, there are two (I)MP34DT0x microphones: one with LR pulled to VDD and the second with LR pulled low.
Two green LEDs (LD1 and LD2), located on the top middle side are available for the user. To light a LED a high logic state HIGH must be written in the corresponding GPIO. Table 2 gives the assignment of the control ports to the LED indicators. UM2708 - Rev 2 page 20/41...

The TAG connector is implemented on the B-L4S5I-IOT01A Discovery kit for the IoT node. The TAG connector is a 10-pin footprint supporting SWD mode, which is shared with the same signals as the ST-LINK. The TC2050- IDC-NL cable is used to link ST-LINK and TAG connector on the B-L4S5I-IOT01A Discovery kit for the IoT node so that the STM32L4+ can be easily programmed and debugged without any extra accessory.
