Description
LinkIt Smart 7688 is a co-design product by Seeed Studio and MediaTek. It brings together the parties' knowledge of open hardware and industry leading reference designs for IoT devices to create this powerful development board.
LinkIt Smart 7688 provides USB host capability that enables it to connect to various USB devices such as webcams, USB drives, keyboards, joysticks and more. The connector is a USB micro-AB type.
LinkIt Smart 7688 are two types of antenna supported one is the default antenna built-in Wi-Fi chip antenna, and the other is I-PEX connector for external antenna(To enable the I-PEX connector, you’ll need to remove the resistor R233 located on the top left corner of the I-PEX connector).
The Linklt Smart 7688 development platform offers two developments boards:
-
Linklt Smart 7688: MPU only. Powered by Media Tek MT7688.
-
Linklt Smart 7688 Duo: MPU and MCU. Powered by Media Tek MT7688 and ATmega 32U4.
LinkIt Smart 7688 is fully supported on the MediaTek Labs site: check out the LinkIt section and register here to download the SDK, participate in the Forums, and more.
Application
