USB Serial Converter

When you do not own an expansion board, it is possible to connect to your device using a USB to Serial adapter.

Note: We do not recommend this setup for beginners.

To connect to your device using a USB to Serial adapter, connect the following pins:

Note: Please ensure the signal and voltage level of your UART adapter does not exceed 3.3V. When possible, change the settings on your adapter.

  • Connect the RX and TX of your USB converter to the TX and RX of the device respectively.
  • To put the device into bootloader mode to update the firmware, you will need to connect P2 to GND. We recommend to connect a button for this.
