Wio Lite W600

Wio Lite W600 is a cost-effective Arduino compatible board with the W600 WiFi module. The Wio Lite W600 features Atmel® | SMART™ SAM D21 ARM Cortex-M0+ based microcontroller and the W600 WiFi core is a 2.4GHz WiFi module features ARM Cortex-M3. Since the Wio Lite W600 uses SAM D21(the same chip used in Arduino Zero) as its Arduino Core, in theory, it is fully compatible with Arduino zero.

It broken out the SAM D21 pins, the I/O level of this board is 3.3V. There are 6 analog pins and 14 digital pins, and also one UART, one I2C, one ICSP port is available. You can power this board with 5V USB Type C and 3.5V~4.2V Lipo battery.

As for the WiFi core, it's our old friend - W600 Module. We've already released the W600 Module and Grove - W600, Wio Lite W600 is a new member of the W600 family. W600 Module features ARM Cortex-M3 with 1MB on-chip flash and freeRTOS kernel. It is CE/FCC certificated and supports 802.11 b/g/n.

On top of that, we've released the Grove Shield for Wio Lite at the same time. With this shield, we bring over 200 Grove sensors, actuators and displays to Wio Lite series and the Feather community.

Hardware Overview

Getting Started


Materials required

  • Wio Lite W600 x1
  • Computer x1
  • USB typc cable x1
Some USB cables can only supply power and cannot transfer data. If you don't have a usb cable or don't know if your usb cable can transmit data, you can check [seeed USB type C support USB 3.1 ](

Connect the Wio Lite W600 to your computer using the USB cable.


Step 1. You need to Install an Arduino Software.

Launch the Arduino application

Double-click the Arduino application (arduino.exe) you have previously downloaded.

If the Arduino Software loads in a different language, you can change it in the preferences dialog. See the [Arduino Software (IDE) page]( for details.

Step 2. Setting your Arduino IDE.

Open your Arudino IDE, click on File > Preferences, and copy below url to Additional Boards Manager URLs

Step 3. Add the Wio Lite W600 Board to Your Arduino IDE

Please follow the Seeed Board Intallation Guide and serch the key word seeeduino_samd_zero to add the Wio Lite W600 into your Arduino IDE.

The key word is **seeeduino_samd_zero**

Step 4. Add the W600 Library into Your Arduino IDE

Download the W600 Library from Seeed Github. Then Refer to How to install library to install library for Arduino.

Step 5. Restart the Arduino IDE. Open the AP-Station example, you can open it in the Arduino IDE by the path: **File --> Examples -->W600_wifi-->log_data.

Step 6. Modify the code with your own AP and Station. In the following picture, Wio Lite W600 work as a station to join the AP marked A and the the Wio Lite W600 will creat the B AP for other devieces. You should change both AP name and password.

Step 7. Select your board and port

You'll need to select the entry in the Tools > Board menu that corresponds to your Arduino. Selecting a Seeeduino Zero.

Choose the right board

Select the serial device of the Arduino board from the Tools | Serial Port menu. This is likely to be COM3 or higher (COM1 and COM2 are usually reserved for hardware serial ports). To find out, you can disconnect your Arduino board and re-open the menu; the entry that disappears should be the Arduino board. Reconnect the board and select that serial port.

Step 8.Upload the code

Now, simply click the "Upload" button in the environment. Wait a few seconds and if the upload is successful, the message "Done uploading." will appear in the status bar.

Upload the code

A few seconds after the upload finishes, then the Wio Lite W600 will access the AP you set and you can use your phone to accees the AP created by Wio Lite W600
