LinkIt Connect 7681 HDK
The LinkIt Connect 7681 development board, co-designed with Seeed Studio, provides easy access
to the five GPIO pins and one UART port — each with an LED — of the MT7681, to quickly connect
peripheral controllers and electronic circuits. The MT7681 is provided on the LinkIt Connect 7681
module, which was co-designed with AcSiP. This module, which is only 15 x 18mm, will also be
available separately for direct integration into your product’s PCB.
Key features of the LinkIt Connect 7681 development board:
•
access to the five GPIO pins and one UART port provided by MT7681, with attached LEDs
•
access t0 the UART port from the USB port.
•
Wi-Fi antenna integrated on LinkIt Connect 7681 module
•
power over USB (Micro USB port)
•
