MT7681
Overview
MediaTek MT7681 is a compact Wi-Fi System-on-Chip (SoC) for IoT devices with embedded TCP/IP stack. By adding the MT7681 to an IoT device, it can connect to other smart devices or to cloud applications and services. Connectivity on the MT7681 is achieved using Wi-Fi in either Wi-Fi station or access point (AP) mode. Visit the overview page to compare different smart home chipsets.
Key features
-
Wi-Fi Station mode: 802.11b/g/n
-
Wi-Fi Access Point mode: 802.11b/g
-
Smart connection APIs to easily create Android or iOS apps to provision a device with wireless AP settings
-
TCP/IP stack
-
Firmware upgrade over UART, APIs for FOTA (firmware over the air) implementation
-
Software PWM emulation for LED dimming
In Wi-Fi station mode, MT7681 connects to a wireless AP and can then communicate with web services or cloud servers. A typical use of this option would be to enable a user to control the heating in their home from a home automation website.
