- Banana Pi R4 WiFi 7 expansion card extender board kit announced: Overview and Features.
SinoVoip has launched a BPI-R4-NIC-BE14 extension card to improve WiFi 7 for the Banana Pi BPI-R4 Router Series.
Today [04/11/2025], the Banana Pi team unveiled an innovative accessory for the Banana Pi R4 board, aimed at significantly enhancing the user experience. This state-of-the-art expansion board empowers users to design custom cases or racks that meet their specific needs.
Additionally, this card is expected to likely resolve some persistent Wi-Fi interference issues by effectively isolating the board from the main R4 board, thereby improving overall performance and connectivity. This development could be a game-changer for enthusiasts looking to maximize the potential of their Banana Pi R4 projects.
Furthermore, this distinct design, separate from the main board, also enables users to craft an effective enclosure that completely isolates any noise, ultimately improving and enhancing Wi-Fi signal strength.
Here’s a first look at the new extension card.
The images provided below illustrate a WiFi extension board made up of two distinct components. One section connects to the current R4 sockets, while the main extension board is equipped with Mini PCIe slots specifically designed for the primary WiFi module. The two boards are interconnected through a power supply and a flat data cable.
