MT7986B(MT7986BC) +MT7975+MT7531 做的高端路由器PCB文件
本帖最后由 armclub 于 2026-9-18 20:45 编辑MT7986BC 属于 MT7986B 系列，联发科 Filogic 830 Wi‑Fi6 SoC，12nm，面向中高端家用路由器、Mesh、AP，BC 后缀一般代表SIP 封装，内置 DDR 内存，是 MT7986B 的集成内存版本，主打 BOM 精简、成本更低。
核心规格
[*]CPU：4×ARM Cortex‑A53 @ 1.6GHz（MT7986A 是 2.0GHz）
[*]无线基带：集成 Wi‑Fi6 双频基带，4×4 2.4G + 4×4 5G，总理论速率 6Gbps
[*]支持 1024QAM、OFDMA、MU‑MIMO、160MHz 带宽、WPA3
[*]网口 MAC：内置两路 2.5GbE MAC，搭配 MT7531 交换芯片实现多 2.5G 口
[*]制程：12nm
[*]内存：BC = SIP 封装，DRAM 封装在芯片内部（不用外挂独立 DDR 颗粒）
[*]硬件加速：FastPath、VPN/IPsec 硬件卸载、MAP-E/T IPv4/IPv6 硬件转发，大幅降低 CPU 占用
[*]安全：TrustZone、Secure Boot、硬件密码引擎
MT7986A / MT7986B / MT7986BC 对比表格
型号CPU 主频内存方案定位
MT7986A2.0GHz外挂 DDR3/DDR4高性能款，红米 AX6000 等
MT7986B1.6GHz外挂 DDR功耗优化版本
MT7986BC1.6GHzSIP 内置 DRAM低成本集成方案，简化 PCB 设计
外设接口
[*]SPI-NOR / SPI-NAND 闪存
[*]USB、GPIO、I2C、UART
[*]MT7986B 系列砍掉部分高速外设，相比 MT7986A无 PCIe，USB 数量更少
常见搭载设备很多新款 AX6000 级别路由器使用 MT7986BC SIP 方案，相比 MT7986A 发热量略低，整机物料成本更低，适合量产消费级路由。
软件生态
[*]Linux 内核 mt76 驱动支持，OpenWrt 原生支持
[*]支持硬件转发、Wi‑Fi offload，适合做软路由、Mesh AP
