The Tinker Board R2.0 shares nearly all of its peripherals with the Tinker Board S R2.0, including the following Rockchip processor:

The only distinction between the mentioned Asus boards is that the former lacks eMMC storage. This Asus SBC utilizes a MicroSD card slot located on the bottom side of the board same as the ‘S’ variant.    

The SBC supports up to 4K resolution at 30 Hz via HDMI, making it a suitable choice for media centers and digital signage applications according to Asus. Additionally, it offers MIPI DSI support for additional display options.
