Youyeetoo R1 Review: A Powerful ARM SBC Boasting rich interfaces with NFC support

Mounting a heat sink

Installing the heat sink was a breeze, even without mounting holes available on the board. The strong adhesive of the thermal pads ensures highly effective heat transfer throughout the entire sink. Amazingly, the board consistently maintains impressively low temperatures, as low as 35°C in idle mode in an open environment, without being enclosed in a case.

Storage Space Details

Out of the original 64GB eMMC capacity, we have set aside 57GB for the operating system files. This means that we still have a generous 43GB of free space available for our everyday use.

This storage option offers ample space for storing files, documents, and media without feeling restricted by limited capacity. It provides a comfortable amount of space that meets the needs of most users. If you require more storage, consider purchasing a Micro SD Card with high write/read speeds, which can offer performance equivalent to that of the eMMC.
