- OpenWrt One Review: The new R4 variant is designed by OpenWrt and Banana Pi teams.
Banana Pi OpenWrt One: An embedded router with enhanced software support
The OpenWrt team finally released their new embedded router board, OpenWrt One, featuring MediaTek MT7981B (Filogic 820) SoC and MediaTek MT7976C dual-band Wi-Fi 6 chipset. This cutting-edge hardware has been designed in partnership with Banana Pi, who will oversee the production and distribution of the router board.
The Banana Pi OpenWrt One marks a significant collaboration with the OpenWrt community.
With the release of OpenWrt 23.05, over 1,800 routers and devices are now officially supported by the lightweight embedded Linux operating system. Many more are claiming to run OpenWrt through a fork of the OS, although these are not developed by the OpenWrt team. Currently, the developers have joined forces with Banana Pi to design their own router board, drawing on their experience with boards like the BPI-R4 Wi-Fi 7 router SBC.
Hardware
The OpenWrt One features a MediaTek MT7981B (Filogic 820) dual-core Cortex-A53 processor operating at 1.3 GHz. It is equipped with 1GB of DDR4 system memory and includes 128 MB of SPI NAND flash for U-boot and Linux 4, ensuring robust performance and efficiency.
As for interfaces and buttons, the device features a USB 2.0 Type-A host port, a USB Type-C port for device or console use, a mikroBUS expansion socket, and a real-time clock. It includes physical reset and user buttons, a boot selection switch for choosing between NAND or NOR storage and supports a 12V power input along with optional compatibility for a Power over Ethernet module.
On the connectivity front, this device is outfitted with two Ethernet ports—one capable of Gigabit speeds and the other delivering an impressive 2.5 GbE. Additionally, it features a MediaTek MT7976C chip, enabling cutting-edge Wi-Fi 6 technology for superior wireless performance.

Banana Pi OpenWrt One: Layout and Interfaces
Striving for affordability
The OpenWrt team carefully chose the router’s specifications to maintain an affordable price of under $100 to stay within this budget. “We opted for interfaces like USB 2.0 instead of USB 3.0 due to limited availability in the Filogic 820 SoC. Although the open-source license for the schematics is undecided, we assure you that they will be made publicly accessible. Rest assured; we will fully comply with GPL requirements by providing a comprehensive machine-readable copy of the corresponding source code.”
Collaborating with Banana Pi Team
Banana Pi was specifically chosen by the OpenWrt developers due to its remarkable alignment with their long-standing requirements. Over the years, the company has gained substantial popularity within the OpenWrt community. Additionally, numerous features are already well-supported in the upstream/mainline U-Boot and Linux systems. It is worth noting that some components such as the 2.5GbE PHY and Wi-Fi firmware employ non-open-source elements, which operate on separate cores independent of the main SoC. Equally, the DRAM calibration routines are also closed-source binaries.
Business model and distribution
The OpenWrt One router board is not only a powerful device but also a promising opportunity to generate income for the project. By partnering with Banana Pi and leveraging their extensive distribution network, we can ensure the widespread availability and adoption of the router board. With every sale, a generous contribution will be made to the Software Freedom Conservancy (SDC), specifically allocated to benefit the OpenWrt community. This revenue will play a crucial role in covering essential expenses such as hosting and organizing OpenWrt conferences. While the exact launch date for the OpenWrt router board is yet to be confirmed, we invite you to delve into the announcement for further details. Together, let’s empower OpenWrt and foster a stronger community!
More details may be found in the official announcement.
Pricing and Availability
Initially unveiled in January 2024, the router’s developer samples were rolled out in April, with early units auctioned at the OpenWrt Summit held in Cyprus on May 18-19. The exciting news is that the OpenWrt One is now widely available on AliExpress for just $89, which includes a full kit with sturdy metal enclosure, a PoE module, three antennas, and a power supply.
