The LinkIt & Trade Connect 7681 module is a low-cost, low-power consumption component for IoT devices. The module integrates the MediaTek MT7681, which supports single stream IEEE 802.11b/g/n, provides GPIO and PWM for intelligent control, and a UART interface for device communication.
The module includes an integrated Wi-Fi antenna and an IPEX socket for an external antenna. 8Mbits flash helps reduce your platform size, along with a power management unit for a single 3.3V power source for cost-effective design.
The 32-bit RISC MCU offers 802.11b/g/n drivers, supplicant, and TCP/IP protocol stack for networking applications, and can operate in station or softAP mode. The module is therefore an ideal solution for embedded devices needing to enable networking services with minimal design effort.
