Thanks for expressing interest in early access! The Reef-Pi Pico is an all-in-one board designed for use with a Raspberry Pi and the Reef-Pi software for a truly open source aquarium controller solution.
The Reef-Pi Pico is a board designed for a Raspberry Pi Zero or Raspberry Pi Zero W Linux single board computers. The beta units do not come with a Raspberry Pi Zero, in conjunction with the Reef-Pi software and Raspbian Linux distribution. It offers a number of ports and built-in hardware to simplify building an aquarium controller using Reef-Pi.
The following products are recommended to make the most out of your Reef-Pi Pico
The following settings for the Raspberry Pi Zero should be used in /boot/config.txt: https://github.com/blueacro/reefpi-pico/blob/master/config.txt

Even though this is a BETA product and not all functions are guaranteed to work excactly as specified, we will happily accept returns for a full refund within a year. If your board fails or suffers a fault, and no more early access boards are available, we will upgrade you to whatever the current product revision is for no charge.
