    9 
    10  - NXP i.MX8M Plus Quadcore 1.6GHz SoC
    11  - 1GB LPDDR4 memory, 8GB eMMC Flash
    12  - Gateworks System Controller (GSC) with integrated EEPROM, button controller, and ADC's
    13  - GPS
    14  - microSD
    15  - I/O connector with I2C, SPI, GPIO
    16  - 1x full-length miniPCIe socket with PCI/USB3 (via mux) and USB2.0
    17  - 1x half-length miniPCIe socket with USB2.0 and USB3.0
    18  - USB Type-C with USB PD Sink capability and peripheral support
    19  - USB Type-C with USB 3.0 host support
    20  - Wide range buck/boost DC supply (3.6V to 20V)
    21 
    22 == Getting Started
    23 
    24 The GW7905 can be powered using the J13 (2-pin) connector (supports 3.6 to 20V DC input) or through the J14 USB Type-C connector using a USB-C charger. The USB-C power profile supports the following profiles by default:
    25 
    26  - PDO1 (low priority) 5V@1.5A
    27  - PDO2 (medium) 15V@1.5A
    28  - PDO3 (high priority) 20V@1.0A
    29 
    30 Other profiles can be programmed into the controller as well. Contact support for other options.
    31 
    32 Depending on the type of cards loaded in the Mini-PCIe sites PD02 or PD03 profiles might be required. The board typically runs at 2.5W without any Mini-PCIe cards installed.

    35 
    36 == Software
    37 
    38 Please use the standard Venice software practices for this SBC, with a note that by default it ships with the i.MX8M Plus SOM. This means all image file names will have the 'p' in the name, indicating the 'plus'
