Compact Mini PCIe wireless card

The YEPLOOK RTL8821CE is a half-height Mini PCI Express adapter that adds dual-band Wi-Fi and Bluetooth 4.2 to laptops, industrial PCs or digital-signage players with a free Mini PCIe slot. It uses the Realtek RTL8821CE chipset and two IPEX MHF antenna connectors in a 2T2R layout. Buyers whose systems only offer M.2 key-E or soldered wireless cannot use this card.

Thermals and power

The small half-height board draws modest power from the Mini PCIe slot and runs without active cooling, so it adds negligible heat inside thin chassis. Passive operation means no fan noise in quiet environments such as office kiosks or medical carts. Power consumption scales with link speed and duty cycle rather than sustaining a fixed peak.

Antennas and driver support

Two external antennas must be supplied separately and connected to the IPEX ports for full 2T2R performance on both 2.4 GHz and 5 GHz bands. The package includes only the card itself, so integrators source cables and dipole antennas to match their enclosure. Windows 7 through 11 drivers enable the advertised 150 Mbps on 2.4 GHz and 433 Mbps on 5 GHz links.

Questions about this item

How do I install the Mini PCI-E card and connect the antennas?

Insert the half-height card into a Mini PCI Express slot and attach the two IPEX MHF connectors to the supplied antenna cables before closing the case.

What maintenance or replacement will the adapter need later?

No scheduled maintenance is required; replace the card only if the Realtek RTL8821CE chipset or the two IPEX antenna connectors fail.

What throughput limit appears first during sustained transfers?

The 5 GHz link caps at 433 Mbps and the 2.4 GHz link at 150 Mbps, so the radio bandwidth is the first bottleneck.
