THE CONFIGURATION
Wi-Fi and Bluetooth are separate software decisions.
The listed configuration combines 2.4 GHz at 150 Mbps, 5.8 GHz at 433 Mbps, USB 2.0 and Bluetooth 4.2. Use those declared functions to define what the host needs, then confirm the software and supplied assembly for both wireless functions.
The photographed marking is V1.1. An older factory reply also names R8821CU_XSB V1.2, but that version has no matching parameter set in the new catalogue. This page describes the V1.1 catalogue entry; its figures are not transferred to V1.2.

HOST INTEGRATION
Match the software to the board.
The catalogue lists Windows XP/Vista/7/8/10/11 and Mac OS for Wi-Fi, with a separate Windows 7/8/10/11 statement for Bluetooth. The Mac OS version is not given. A Wi-Fi OS statement therefore must not be read as Bluetooth support for the same host.
Bluetooth boundary
The catalogue declares Bluetooth 4.2. Confirm its matching driver and host conditions separately from Wi-Fi.
Your host conditions
Identify the host, installation form, available connection, antenna location and evaluation criteria. No device-level compatibility test is implied by this reference.
BOARD PROCUREMENT
Specify the assembly you need to receive.
A board reference identifies the starting configuration. It does not define every item in the delivery.
Connection
Define connector, pads or leads, pin assignments and required input supply.
Mechanical fit
Provide actual board outline, holes, component height and host clearance requirements.
Antenna & included items
Agree antenna, cables, fixings and documents as included, optional or excluded.
Evaluation & changes
Request a version-matched drawing and driver where needed; describe any change for assessment.
KEEP THE CONFIGURATIONS DISTINCT
