Overview
- The only difference between this Roku Premiere+ (3921X) and
- Roku Premiere (3920X) is the remote included with the device.
- The Premier+ (3921X) includes the Voice remote with TV power and
- volume buttons while the Premier (3920X) includes the simple remote.
The wireless chip ID is not legible in the FCC photos but it is a 24-pin QFN from Realtek.
- This suggests a RTL8188FTV (USB 2.0) or a RTL8189FTV (SDIO). Both are 1x1:1.
