Mechanical Specification

Electrical Specification

Power Requirements
The Radxa X4 supports the following power input:

USB Type‑C PD Version 2.0 with 12V/2.5A.
It can also be powered through a PoE HAT.

The recommended power source should be able to produce, at least, 18W without power consuming devices on USB or 25W with full USB ports load.

GPIO Voltage

Operating Conditions

The Radxa X4 can operate normally within a temperature range of 0°C to 60°C.
Its BIOS factory settings limit the CPU power consumption (Power Limit 1) to 6W. Simi‑ larly, the Thermal Design Power (TDP) of the Intel® Processor N100 is also 6W. This implies that under the high‑load workload defined by Intel®, the processor operates at its base fre‑ quency with all cores active, resulting in an average power consumption of 6 watts.

Peripherals

GPIO Interface
