3.2.2.8 I2C Interface
I2C General Purpose signals are managed by SoC I2C5 bus.
I2C_GP_CK: I2C General Purpose clock signal. Bi-Directional between the module to the Carrier board, electrical level +1.8V_RUN with a 2k2Ω pull-up resistor
I2C_GP_DAT: I2C General Purpose data signal. Bi-Directional between the module to the Carrier board, electrical level +1.8V_RUN with a 2k2Ω pull-up resistor
On this bus a selection of addresses must be left reserved for on-board peripherals as presented in this table:
I2C5 Bus
Address Peripheral
0x50 EEPROM
I2C Power Management signals are managed by SoC I2C1 bus.
I2C_PM_CK: Power management clock signal. Bi-Directional between the module to the Carrier board, electrical level +1.8V_ALW with 2.2
I2C_PM_DAT: Power management data signal. Bi-Directional between the module to the Carrier board, electrical level +1.8V_ALW with 2.2
On this bus a selection of addresses must be left reserved for on-board peripherals as presented in this table:
I2C1 Bus
Address Peripheral
0x40 Embedded Controller
0x25 PMIC
0x48 Secure Element
3.2.2.9 Asynchronous Serial Ports (UART) interface signals
All UART interface signals are directly managed by the i.MX 8M Plus processor. In all versions, the edge connector offers the four following UART interfaces.
SER0_TX: UART #2 Interface, Serial data Transmit (output) line, +1.8V_RUN electrical level
SER0_RX: UART #2 Interface, Serial data Receive (input) line, +1.8V_RUN electrical level with a 100kΩ pull-up resistor
SER0_RTS#: UART #2 Interface, Handshake signal, Request to Send (output) line, +1.8V_RUN electrical level
SER0_CTS#: UART #2 Interface, Handshake signal, Clear to Send (Input) line, +1.8V_RUN electrical level with a 100kΩ pull-up resistor
SER1_TX: UART #4 Interface, Serial data Transmit (output) line, +1.8V_RUN electrical level
