Specifications

ROCK Pi 4C Plus Product Brief
The analog audio output can drive 32 Ohm headphones directly.
5.7 M.2 Connector
The ROCK Pi 4C Plus oers a M.2 M Key socket with PCIe 2.0 x4 interfaces, providing high speed bus
access, a standard M.2 2230 mouting hole is on board for 2230 form facor NVMe SSD. SATA SSD is not
supported.
5.8 Temperature Range and Thermals
The recommended ambient operating temperature range is 0 to 50 degrees Celcius.
To reduce thermal output when idling or under light load, the ROCK Pi 4C Plus reduces the CPU clock
speed and voltage. During heavier load the speed and voltage (and hence thermal output) are in‑
creased. The internal governor will throttle back both the CPU speed and voltage to make sure the
CPU temperature never exceeds 85 degrees C.
The ROCK Pi 4C Plus will operate perfectly well without any extra cooling and is designed for sprint
performance ‑ expecting a light use case on average and ramping up the CPU speed when needed
(e.g. when loading a webpage). If a user wishes to load the system continually or operate it at a high
termperature at full performance, further cooling may be needed.
6 Availability
ROCK Pi guarantee availability ROCK Pi 4C Plus until at least September 2029.
