Fri Jun 9 18:54:51 CEST 2023
The Gateworks imx8mp-venice-gw7905-2x consists of a SOM + baseboard.
The GW702x SOM contains the following:
- i.MX8M Plus SoC
- LPDDR4 memory
- eMMC Boot device
- Gateworks System Controller (GSC) with integrated EEPROM, button
controller, and ADC's
- PMIC
- SOM connector providing:
- eQoS GbE MII
- 1x SPI
- 2x I2C
- 4x UART
- 2x USB 3.0
- 1x PCI
- 1x SDIO (4-bit 3.3V)
- 1x SDIO (4-bit 3.3V/1.8V)
- GPIO
The GW7905 Baseboard contains the following:
- GPS
- microSD
- off-board I/O connector with I2C, SPI, GPIO
- EERPOM
- PCIe clock generator
- 1x full-length miniPCIe socket with PCI/USB3 (via mux) and USB2.0
- 1x half-length miniPCIe socket with USB2.0 and USB3.0
- USB 3.0 HUB
- USB Type-C with USB PD Sink capability and peripheral support
- USB Type-C with USB 3.0 host support
