MT7688 Duo getting started

Now days I am putting together a basic kit for an IoT course that I am designing.
The kit consists of items purchased from Visha World.
This is what it looks like at the moment.

All of the above components - except MT7688 Duo - can be purchased online from Visha World. For MT7688 Duo, you can visit seeed studio and order it from them. Once I am done designing the course, the details will be available on our training website over at and the kit as a whole will be made available at

As of now, the kit consists of the following:

  1. MT7688 Duo [Buy]
  2. 4GB MicroSD Card
  3. 8 Channel Relay board controllable over USB [Buy]
  4. CH340G Based USB UART
  5. Breadboard [Buy]
  6. Breadboard patch cables 40 way Male to Female 200mm long [Buy]
  7. Breadboard patch cables 40 way Female to Female 200mm long [Buy]
  8. Breadboard patch cables 40 way Male to Male 200mm long [Buy]
  9. USB OTG Cable
  10. DHT11 Temperature Humidity Sensor [Buy]
  11. 0.96" OLED Display [Buy]
  12. microUSB cable for MT7688 Duo's Microprocessor
  13. miniUSB Cable for Relay Board

Step 1: Gaining access to the serial console.
The first thing I did when I got my MT7688 Duo was to get access to its console over UART. For that I used CH340G based USB-TTL convertor with its voltage set to 3.3V. Here is a photo and screenshot:

For wiring details, have a look at Seeed Studio's Wiki Page for MT7688 here.

Step 2: Connecting the MT7688 Duo as a client to your home's WiFi Connection
To know how to connect your MT7688 Duo to your home/office WiFi network, have a look at Seeed Studio's Wiki Page for MT7688 here.

Step 3: Mounting the microSD card
Insert the microSD card and then via the serial console, issue the commands:

cd /dev
mount -t vfat mmcblk0p1 /mnt/

Then issue the command:
df -h
and you will note the microSD card showing up in the list.
