I think my mcu or other boards are broken. I see you give away the 3 boards as a gift if a person buys a brewie from you. Can you add the boards to your store so we can buy them separately?
also, if you are not selling the brewie units, consider lowering the price because the brewie + units are available on amazon for almost the same price making it a tough sell for the older model.
lastly, it would be cool if you had an entire rebuild kit that had all the parts for a brewie, possibly at a slight discount. Burners, valves, pumps, tubing, weight sensors, control boards, etc.
