The HalloWing M4 board should arrive ready-to-scare. Connect a battery or USB cable, move the power switch to the “on” position, and after a few seconds you should get a blinking eye.

The next couple of pages cover…

• How to install or update the eye firmware for the latest features and bug fixes.
• Loading different eye designs.

These pages reference the MONSTER M4SK board repeatedly…but the principle is exactly the same, just on a smaller board with a single eye.
