Description
MediaTek LinkIt™ 7697 HDK is an IoT development platform
for RTOS based on MediaTek MT7697, a highly integrated SOC
that features an ARM® Cortex®-M4 with floating point unit
microprocessor that operates at up to 192MHz with low-
power 1x1 802.11 b/g/n 2.4GHz Wi-Fi and Bluetooth Low
Energy support. This HDK is compact in size but includes all
the necessary pin-breakouts to integrate a variety of
peripherals and enable development of highly connected
applications.
