| 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' |
