Introduction

Overview

MediaTek LinkIt™ 7697 hardware development kit (HDK) is part of LinkIt development platform for RTOS and is
based on a highly integrated MediaTek MT7697 SOC with an application processor, a low power 1x1 11n single-
band Wi-Fi subsystem, a Bluetooth Low Energy subsystem and a Power Management Unit. The application
processor subsystem contains ARM Cortex-M4 with floating point unit microprocessor.
The HDK supports peripherals, including UART, I2C, SPI, I2S, PWM, IrDA and auxiliary ADC. It also includes an
embedded SRAM/ROM. The Wi-Fi subsystem contains 802.11b/g/n radio, baseband and MAC that are designed to
meet both the low power and high throughput application requirements. It runs on a 32-bit RISC CPU that could
fully offload the application processor. The Bluetooth Low Energy subsystem contains the Bluetooth radio,
baseband and link controller and uses the same 32-bit RISC CPU for the Bluetooth protocols. The LinkIt 7697 HDK is
shown in Figure 1.
The main features of this HDK are:
•
Breadboard compatible form factor. Developers can use breadboards to connect peripherals with this
HDK conveniently to build their applications.
•
Auxiliary LED and buttons to reset the board and to program a user-defined functionality.
•
An on-board USB-to-UART conversion chip to access logs and conveniently update the firmware.
•
Serial Wire Debug (SWD) interface.
•
mt76x7-uploader tool, enables the HDK to switch between flash normal mode and recovery mode
automatically without user intervention.
•
Developers can program the board with the native LinkIt SDK using GCC, IAR embedded workbench, or
Keil µVision IDE. Development with Arduino IDE is also supported.
