QCS6490 interfaces
Choose the right connection for networking, cameras, and peripherals.
The documented QCS6490 configuration offers several ways to connect a workstation, network, camera, and robot peripherals. Connector placement and availability can change with the carrier or enclosure. Identify the connector on the physical unit before attaching a cable.
External connections
| Interface | Documented configuration | Typical use |
|---|---|---|
| Ethernet | Two RJ45 ports; one listed at 2.5 Gbps and one at 1 Gbps | Local development network or a dedicated robot network |
| Wi-Fi / Bluetooth | Dual-band 802.11ax Wi-Fi and Bluetooth 5.1 | Wireless setup and peripheral connectivity |
| USB-A | Four USB 3.0 host ports sharing an aggregate bandwidth budget | Keyboard, storage, camera, or debugging accessories |
| USB-C | One USB 3.0 connection with DisplayPort 1.4 support in the documented configuration | USB debugging or a compatible display path |
| Audio | One 3.5 mm connection | Audio input/output as supported by the installed image |
The supplied material also describes camera, display, CAN, RS-232, RS-485, UART, SPI, I²S, GPIO, and isolated I/O connections on its carrier. Those are not interchangeable connector standards. Their physical pinout, voltage, isolation, and availability must be checked against the exact Qmini assembly before wiring.
Choose a development connection
For first access, use a trusted local Ethernet network or a USB data cable. QCS6490 bring-up covers the read-only connection checks. After the device is reachable, Connect to the device explains SSH and ADB workflows.
Electrical safety
Do not infer pin voltage from an interface name or a software example. Never apply external power to a signal pin, connect an unknown serial voltage directly to UART, or use a GPIO as a motor supply. Disconnect motor power during initial software tests. If a peripheral needs CAN, RS-485, or another industrial signal, use the connector and transceiver specified for the shipped unit.
