GPIO Alternate Functions


USB
Radxa Cubie A7Z features a typec USB 3.1 OTG port with DP Alt mode available, with a downstream current limit of approximately 1A. It also includes a USB 2.0 OTG port (Type C), which can be powered by a 5V PSU or a PC/laptop USB port, supporting both power and data transfer.

HDMI
Radxa Cubie A7Z provides 1 × Micro HDMI port with CEC and HDMI 2.0 support, allowing for resolutions up to 4K60p.

FPC Connector
The Cubie A7Z offers a FPC connector providing PCIe 3.0 onelane signal, supporting expansion of SSD, SATA, 2.5G Ethernet ports and other devices, This requires additional expansion board / HAT.

Temperature Range and Thermals
Recommended ambient operating temperature: 0°C to 50°C
The board dynamically adjusts CPU clock speed and voltage to minimize thermal output during idle or light load, and increases them under heavy load. The internal governor ensures the CPU temperature does not exceed 85°C.
The Cubie A7Z operates reliably without additional cooling for typical use. For sustained heavy workloads or operation in hightemperature environments, additional cooling may be required.

Mechanical Specification
Note: All dimensions are in millimeters (mm).
