Did you perhaps overlook it? An in-depth analysis of the Youyeetoo X1.
Youyeetoo R1 Review – Product information and price details.

Part I: Youyeetoo R1 SBC – Product Introduction

The youyeetoo R1 is a powerful Rockchip RK3588S SBC, featuring a wide range of capabilities within a compact 100×69.3 mm form factor. It includes two M.2 sockets for NVME/SSD or 4G LTE, as well as Wi-Fi and Bluetooth connectors. Additionally, it supports NFC, four display interfaces, two MIPI CSI camera interfaces and much more.

The board is equipped with the possibility of having up to 32GB of RAM and 256GB of eMMC flash storage. Additionally, it includes a high-speed gigabit Ethernet port, five USB interfaces for convenient connectivity, a built-in microphone, multiple audio inputs and outputs, and a versatile 30-pin header for expansion. Furthermore, it accommodates HDMI input through an adapter that can be connected to one of the MIPI CSI ports.

Package Contents	youyeetoo R1 x1 (With Heat Sink)
Astimate Price	Starting at $99

Youyeetoo offers extensive support for Android 13, Debian 11, Ubuntu 22.04, and Buildroot, all built upon the solid foundation of Linux 5.10. Although the wiki is a work in progress, it is continually improving to provide even more valuable information.

Initially, we were worried about the absence of cooling options and the absence of mounting holes for a heat sink or fan in this product. However, the company has intentions to launch a metal enclosure at a super low cost of $5.00.

NFC Support

It is likely the first Rockchip RK3588 or RK3588S board to have integrated NFC support. While the importance of this feature is uncertain, it is worth noting that a USB NFC reader can always be added. If NFC capability is a priority, the Youyeeto R1 could be a more cost-effective option, considering that USB NFC readers typically sell for $30 to $60 on Amazon, and the NFC antenna required by the Rockchip board costs only about $4.00.
