LinkIt 7697 is a co-design product by Seeed Studio and MediaTek. As the latest member of the LinkIt family, it uses the MediaTek MT7697 SoC and aims at providing lightweight IoT solution. It may reminds you of LinkIt Smart 7688/Duo, another development board which released in 2015. Both of them are born for IoT however they are quite different.
The chipset of LinkIt 7697 is MT7697, a highly integrated single chip which features an application processor, a low power 1x1 11n single-band Wi-Fi subsystem, a Bluetooth subsystem, and a Power Management Unit. The application processor subsystem contains ARM Cortex-M4F MCU. It also includes many peripherals, including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC.
For programming, you can program the board with the native LinkIt SDK using GCC, IAR embedded workbench, or KEIL uVision. In order to make it easier to use, LinkIt 7697 also provides a porting layer to the popular Arduino IDE - so that you can use your existing Arduino sketches and peripheral driver libraries.
If comparing with Arduino UNO, you will find that the LinkIt 7697 is more powerful as it can run more complicated and store larger program, IoT application friendly and cost effective, you can even plug it into a breadboard directly and start your IoT project right away.

Hi john, please check the Low Power Mode and Power measurement by MTK. #### https://docs.labs.mediatek.com/resource/mt7687-mt7697/en/tutorials/low-power-mode-and-power-measurement ####
Hi Dear Customer, here is the link for different development environment options https://docs.labs.mediatek.com/resource/mt7687-mt7697/en/get-started-linkit-7697-hdk thanks. Bill
Hi there~ Bluetooth : No. LinkIt 7697 does not support A2DP.
Wi-Fi: Yes. You can pretty much send any thing via Wi-Fi. However, you have be aware the fact that LinkIt 7697 does not have an audio interface such as I2S or TDM.
Hi,jia-Ning,have you installed related library correctely? please install it under directory arduino/libraries,Regards~!
Hi there, I follow the procedure and it works well. please follow https://docs.labs.mediatek.com/resource/mt7687-mt7697/en/get-started-linkit-7697-hdk/gcc-arm-embedded-linkit-7697/download-project-binary-with-flash-tool-linkit-7697 and especially the time slot for releasing button. thanks.
Hi there, please drop a mail to firstname.lastname@example.org or forum.seeedstudio.com. let's see what we can help. thanks.
Hi there~ It do not support Particle now, cause Particle does not provide a device-end SDK as far as I know.Regards
Yes, LinkIt 7697 supports WiFi and BLE connection in the same project without rebooting.
Hi there, We don’t have a specific .svd file for LinkIt 7697. You may want to take a look in the Keil Supporting Package for MT7697: https://docs.labs.mediatek.com/pages/viewpage.action?pageId=12878815
(The .pack file is actually a .zip file that can be unzipped to check the content). thanks.
@bill.yu Hi Bill, it seems you are from the manufacturer of Linkit 7697. I am considering to use WRTNODE(the module part of Linkit 7697) in my product. Please let me know how to contact you.
