    Works right out of the box.
  

*by J***M on Reviewed in the United Kingdom on October 9, 2021*

The board works right out of the box. Simply insert the Onion Omega board and connect it to a power source via USB and you are ready to go. Communication with the Omega works headless, i.e. you connect via WiFi. The Omega chip is independent of the board for communication or programming. However, the board is very convenient and safe for powering the chip and easy GPIO access.
