LoPy 4

• Before connecting your module to an Expansion Board 3.0, you should update the firmware on the Expansion Board 3.0. Instructions on how to do this can be found here.

• Look for the reset button on the module (located at a corner of the board, next to the LED).

• Locate the USB connector on the expansion board.

• Insert the LoPy4 module on the Expansion Board with the reset button pointing towards the USB connector. It should firmly click into place and the pins should now no longer be visible.

• Before connecting your module to a Pysense/Pytrack/Pyscan board, you should update the firmware on the Pysense/Pytrack/Pyscan. Instructions on how to do this can be found here.

• Look for the reset button on the LoPy4 module (located at a corner of the board, next to the LED).

• Locate the USB connector on the Pysense/Pytrack/Pyscan.

• Insert the module on the Pysense/Pytrack/Pyscan with the reset button pointing towards the USB connector. It should firmly click into place and the pins should now no longer be visible.

• Firstly you will need to connect power to your LoPy4. You will need to supply 3.5v-5.5v to the Vin pin.

• The connect the RX and TX of your USB UART to the TX and RX of the LoPy4 respectively.

• In order to put the LoPy4 into bootloader mode to update the device firmware you will need to connect P2 to GND. We recommend you connect a button between the two to make this simpler.

Note: This method of connection is not recommended for first time users. It is possible to lock yourself out of the device, requiring a USB connection.

• In order to access the LoPy4 via WiFi you only need to provide 3.5v - 5.5v on the Vin pin of the LoPy4:

• By default, when the LoPy4 boots, it will create a WiFi access point with the following credentials:

  • SSID: lopy4-wlan

  • password: www.pycom.io

• Once connected to this network you will be able to access the telnet and FTP servers running on the LoPy4. For both of these the login details are:

  • username: micro

  • password: python
