1. Article purpose[edit | edit source]↑

This article provides an overview of STM32MP157x-DKx Discovery kits. It briefly describes:

  • how to assemble the different elements provided in the commercial box
  • what are the different components present on the board
  • how to connect the board to external material
  • how to configure the board for boot
  • what are the configurations of the connector pins

Template:Warning

2. Board assembly[edit | edit source]↑

The STM32MP15 Discovery kit packages (STM32MP157X-DKX) include the items listed below.

Please note that;

  • the STM32MP157X-DK1 Discovery kit neither includes the "WLAN + Bluetooth" component (muRata LBEE5KL1DX), nor the MB1407 daughterboard DSI display
  • the STM32MP157X-DK2 Discovery kit includes the "WLAN + Bluetooth" component (muRata LBEE5KL1DX), and the MB1407 daughterboard DSI display

The different variants corresponding to STM32MP157X-DK1/2 are explained by the part number codification.

Position Description
1 MB1272 motherboard ("WLAN + Bluetooth" component included only for the STM32MP157X-DK2 Discovery kit)
2 MB1407 daughterboard DSI display (480x800 pixels): only for the STM32MP157X-DK2 Discovery kit
3 microSD card
4 DSI ribbon cable: only for the STM32MP157X-DK2 Discovery kit
5 Spacer for DSI display daughterboard: only for the STM32MP157X-DK2 Discovery kit
6 USB Type-C (power 5V-3A)


The following figures explain how to assemble the various items to obtain the STM32MP15 Discovery kit.

For STM32MP157X-DK1 kits, the assembly only consists in inserting the microSD card into the dedicated slot (step C in the below figures).

Details about some LEDs:

  1. ↑ LD4: flashes red if ST-LINK/V2-1 connection not established, else green
  2. ↑ Jump up to: 2.0 2.1 2.2 2.3 LD5, LD6, LD7, LD8: some user LEDs are used to reflect the system activity, while the others are left free to be used by the application, as explained in LEDs and buttons on STM32 MPU boards article
  3. ↑ LD3: flashes green when Ethernet connection established
  4. ↑ LD2: turns green if power connection established
  5. ↑ LD1: turns red if USB Type-A connection established

4. Board connection[edit | edit source]↑

The connections shown in the picture below are the ones recommended to start with the STM32MP157X_DKX Discovery kits. As shown in the board overview, other connectors are available for these boards (for example HDMI).

5. Boot related switches[edit | edit source]↑

The following table defines the different combination of the boot mode selection switches: Template:Info

Boot modes

6. GPIO mapping[edit | edit source]↑

6.1. GPIO expansion connector[edit | edit source]↑

The pins of the GPIO expansion connector (CN2 on the board overview picture) are described in the following table:

GPIO expansion connector
Function STM32 pin Pin Pin STM32 pin Function
3V3 - 1 2 - 5V
GPIO2 / I2C5_SDA PA12 3 4 - 5V
GPIO3 / I2C5_SCL PA11 5 6 - GND
GPIO4 / MCO1 PA8 7 8 PB10 GPIO14 / USART3_TX
GND - 9 10 PB12 GPIO15 / USART3_RX
GPIO17 / USART3_RTS PG8 11 12 PI5 GPIO18 / SAI2_SCKA(1)
GPIO27 / SDMMC3_D3 PD7 13 14 - GND
GPIO22 / SDMMC3_CK PG15 15 16 PF1 GPIO23 / SDMMC3_CMD
3V3 - 17 18 PF0 GPIO24 / SDMMC3_D0
GPIO10 / SPI5_MOSI PF9 19 20 - GND
GPIO9 / SPI5_MISO PF8 21 22 PF4 GPIO25 / SDMMC3_D1
GPIO11 / SPI5_SCK PF7 23 24 PF6 GPIO8 / SPI5_NSS
GND - 25 26 PF3 GPIO7
I2C1_SDA(2) PF15 27 28 PD12 I2C1_SCL(2)
GPIO5 / MCO2 PG2 29 30 - GND
GPIO6 / TIM5_CH2 PH11 31 32 PD13 GPIO12 / TIM4_CH2
GPIO13 / TIM3_CH2 PC7 33 34 - GND
GPIO19 / SAI2_FSA(1) PI7 35 36 PB13 GPIO16 / USART3_CTS
GPIO26 / SDMMC3_D2 PF5 37 38 PI6 GPIO20 / SAI2_SDA(1)
GND - 39 40 PF11 GPIO21 / SAI2_SDB(1)

(1) The SAI2 is shared between the audio codec and the GPIO expansion connector. By default, the SAI2 is connected to the audio codec thanks to Solder Bridge SB13, SB14, SB15, and SB16: more details in the STM32MP157x-DKx discovery board user manual.
(2) Warning: the I2C1 is used to communicate with several on-board peripherals, but is also available on the GPIO expansion connector. So, it is important to ensure that new components added on the I2C1 connection will not disturb the bus behavior.

6.2. Arduino Uno connector[edit | edit source]↑

The pins of the Arduino Uno connector are described in the following table:
