This placement is designed for the [WIFI-5 OEM module](/WIFI-5) and is connected via a USB 2.0 to the LAN9514 chip.
<br/>
This module is based on the MediaTek MT7601U chip and is fully supported by the Raspberry Pi OS.
<br/>
It can be molded directly on a the CM Home PCB. It works just as client (no access point mode).

Two types of antennas are available:

* PCB antenna (Code AN-WIFI-01)
* Rubber antenna (Code AN-WIFI-02)

Alternatively, a [WIFI-3 USB dongle](/WIFI-3) can be used, which supports access point mode at 2.4 and 5.8 GHz.
