• Power Requirements

  The Radxa ROCK 4A supports various way of powering, smart power adapter as well as fixed voltage:

  – USB PD 2.0 Support USB Type C PD 2.0, 9V/2A, 12V/2A, 15V/2A, 20V/2A

  – Qualcomm® Quick Charge™ 2.0 Support QC3.0/2.0 adapter, 9V/2A, 12V/1.5A

  – Power adapter with fixed voltage from 6V to 24V on the USB Type C power port

  – 5V Power from the GPIO PIN 2 & 4

• Operating Conditions

  Recommended environmental temperature: 0 ~ 50°C

  Radxa ROCK 4A has a temperature limit of 80°C, beyond which it throttles clock speeds for reliability.

  For continuous high-performance use, external cooling methods like heat sinks or fans can maintain maximum clock speed below the 80°C limit
