OpenWrt One/AP-24.XY router board is based on the MediaTek MT7981B (Filogic 820) SoC and MediaTek MT7976C dual-band WiFi 6 chipset. It is the first official development board from the OpenWrt open-source community, co-designed with Banana Pi.
OpenWrt One utilizes MediaTek's MT7981B SoC, featuring dual ARM Cortex-A53 cores clocked at 1.3 GHz. It comes equipped with 1 GB DDR4 RAM and 256 MB SPI NAND storage, integrating an additional 16 MB protected storage for system backup. Dual storage hardware safeguards the onboard system.
OpenWrt One integrates an M.2 SSD interface, with a 2230/2242 NVMe PCIe 2x1 port available for adding external storage. It provides one USB 2.0 Type-A port and one mikroBUS expansion port, offering additional interfaces for a wide range of technical possibilities.
MediaTek MT7981B is a compact Wi-Fi system-on-chip (SoC) for IoT devices, incorporating an embedded TCP/IP stack. Using the MT7981B, IoT devices can connect to other smart devices or cloud applications and services. Connectivity on the MT7981B is achieved via Wi-Fi in either Wi-Fi station or access point (AP) mode. The MT7981B provides 5 GPIO pins and 1 UART port. Additionally, PWM is supported in the application software.
OpenWrt One/AP-24.XY router features Wi-Fi 6, dual-band, 3×3/2×2 MIMO, 1 × 2.5 G WAN network interface, and 1 Gigabit LAN network interface. It is suitable for maker DIY projects, OpenWrt software learning and development, IoT applications, Wi-Fi 6 wireless routing applications, NAS, and network communication applications.
