Raspberry Pi Compute Module 4 Antenna Kit


This antenna kit is launched in conjunction with the Compute Module 4 from the Raspberry Pi Foundation. CM4 with built-in wireless models comes with an onboard U.FL connector for an external antenna, thus this antenna kit. This Antenna Kit is certified for use with the Raspberry Pi Compute Module 4. If a different antenna is used, then separate certification will be required, and this must be arranged by the end-product design engineer.

Note: The U.FL connector is only populated on Compute Module 4 with Wireless, the non-wireless variations/models DO NOT come with a U.FL connector and wireless metal “can”.

This antenna kit comes with SMA (Female) bendable (0º to 90º) antenna and RF cable with RP-SMA (male) with MHF1/U.FL connector and is 205mm length. You can mount the SMA antenna to an external case/enclosure to extend the wireless signal.

Note: CM4 (with wireless) is capable of switching the use of onboard PCB antenna or external antenna from software/IO.
