DC-in jack connector The input voltage of theConnectCore MP25 Development Board is 5V. This input power supply is provided via a DC-in power jack connector. Note There is an additional 2-pin power connector (J5) not populated by default. An overvoltage circuit protects the board from overvoltage and overcurrent events. Downstream from these input power protections, there are two regulators/switches for powering the carrier board circuitry: n 5V load switch (U4): A 5V load switch that controls the power delivery to different interfaces on the carrier board. n 3.3V On-board regulator (U3): A regulator that provides 3.3V to different peripherals of the development board. RTC The ConnectCore MP25 Development Board supports an external RTC, which is powered from an on-board supercap (C5). This supercap also powers the internal RTC of the ConnectCore MP25 module. Power and reset buttons One power button (SW1) and one reset button (SW2) are included on the development board. System boot The ConnectCore MP25 module supports different boot modes (see the ConnectCore MP25 System-on-Module Hardware Reference Manual for detailed information). A quadruple switch (S1) allows you to select the desired mode: ConnectCore MP25 Development Board 13 Interfaces Debug interfaces S1.1 Open Close Open Close Open Close Open Close Open Close S1.2 Close Close Open Open Close Open Close Open Close Open S1.3 Open Open Open Open Close Close Open Open Close Close S1.4 Open Open Open Open Open Open Close Close Close Close A35 Master UART/USB SD-Card eMMC Development S-NOR Development UART/USB A33 Master UART/USB Development SD-Card eMMC S-NOR Development UART/USB Note To boot from microSD you must use the SDMMC1 interface, which is connected to the wireless chip internally in the SOM. This means that only non-wireless variants of the CCMP2 can boot from an external microSD. Debug interfaces JTAG The ConnectCore MP25 Development Board provides a Tag Connect footprint for accessing the STM32MP25 JTAG debug port. Additionally, a standard 10-pin, 1.27 mm pitch connector (J21) is available for accessing the JTAG interface: Pin Signal name Description 1 JTMS-SWDIO Mode select line 2 VDDIO 3.3V power supply 3 JTCK-SWCLK Clock line 4 GND 5 JTDO-TRANCESWO Data output line 6 GND 7 JTDI Data input line 8 NC 9 NRST Reset line of the CPU 10 GND ConnectCore MP25 Development Board 14 Interfaces Multimedia CAUTION! Pinout mirrored compared to standard pinout. Console port A dedicated USB type-C connector (J19) provides access to the console port of the ConnectCore MP25 system-on-module. This USB port is routed directly to a bridge that converts the USB bus into TTL level. USART2 is used as the console debug port of the STM32MP25 CPU. This USART can also be accessed directly at TTL level through J20 connector (not populated by default): Pin Signal name Description 1 CONSOLE_A35_TX USART transmission line 2 CONSOLE_A35_RX USART receiver line 3 3V3_SOM 3.3V power supply 4 GND Default console port settings: n Baud rate: 115200 n Data: 8 bit n Parity: none n Stop: 1 bit n Flow control: none Multimedia HDMI The ConnectCore MP25 system-on-module supports only one MIPI-DSI display interface. On the development board, this MIPI-DSI interface is connected to the Lontium LT8912B bridge to convert it to HDMI. The HDMI is available over a standard HDMI connector (J32). Note The native MIPI-DSI interface of the ConnectCore MP25 module is also available on a 40 pin, 0.5 mm pitch connector (J27), which is not populated by default.

Communication Gigabit Ethernet Up to three 10Base-T/100Base-Tx/1000Base-T Ethernet interfaces are fully integrated in the ConnectCore MP25 development board through the Marvell 88E1512 Ethernet PHY. These interfaces are available over RJ45 connectors with integrated link/activity LEDs. Note The third Ethernet port is only available on ConnectCore MP25 variants using the STM32MP257 variant of the CPU. RS-485 RS-485 standard is supported on the ConnectCore MP25 development board through USART6. The interface is available on connector J11: Pin Signal name 1 3V3_BOARD 2 RS485_B 3 RS485_A 4 GND Description 3.3V power supply RS485 B line RS485 A line You can connect a 120 termination resistor to the port by closing J10. CAN Two CAN FD buses are available on the development board through connectors J14 (CAN1) and J17 (CAN2). The pinout of these connectors is as follows, where x refers to the CAN interface on each connector: Pin Signal name Description 1 5V_BOARD 5V power supply 2 CANx_H CAN high line 3 CANx_L CAN low line 4 GND You can connect a 120 termination resistor to each port by closing J13 (CAN1) and J15 (CAN2). ConnectCore MP25 Development Board 18 Interfaces User interfaces USB Host The ConnectCore MP25 Development Board offers support for four USB Host interfaces. Two of them are available over a stackable dual USB A-type connector. The third USB Host is connected to the PCI Express Mini card connector. The fourth is connected to the XBee socket. All USB Hosts can operate at low-speed, full-speed and hi-speed. USB type-C port controller One USB type-C port controller is available on the development board, supporting USB 2.0. Note The STM32MP25 integrates a COMBOPHY which supports USB3 SuperSpeed and PCIe gen2. By default, the ConnectCore MP25 development board connects the COMBOPHY to the Mini PCIe socket supporting the PCIe interface. However, the development board also allows you to connect the COMBOPHY to the USB type-C port to support USB3 SuperSpeed by modifying the following 0-ohm resistors. n Remove R232, R234, R236 and R238 n Populate R233, R235, R237 and R239 Mini PCI Express slot The ConnectCore MP25 Development Board provides a Mini PCI Express socket supporting both USB and PCIe connection to the ConnectCore MP25 module. A micro SIM socket is also connected to the Mini PCI Express slot. XBee socket One XBee socket is populated on the development board, supporting XBee Cellular modules. The UART bus connected to the XBee socket is also the default debug port for the Cortex-M33. This UART is also accessible on connector J12. MikroBus socket The ConnectCore MP25 Development Board provides a socket compatible with MikroElektronika MikroBus click boards, supporting I2C, UART, SPI, ADC and PWM connectivity. Wireless The ConnectCore MP25 System-on-Module supports IEEE 802.11 a/b/g/n/ac/ax and Bluetooth 5.4 with on-module U.FL connector. For complete WLAN specification, refer to the ConnectCore MP25 System-on-Module Hardware Reference Manual. Additionally, the development board supports a U.FL connector (J46) which is routed directly to a SMA connector (J47). The purpose is to adapt the U.FL form factor to the SMA form factor to extend the number of antennas that can be used on the development board for either the onmodule antenna path or any other RF path that could be used on a PCIe or XBee board. User interfaces Three LEDs are available on the development board, two of which are shared with user button. A tamper button is also available.
