Ubo Pro 4/5 - Founder's limited edition

This is a carefully crafted piece of hardware with attention to details and premium materials. I personally stain and varnish the top walnut wood with unnecessary obsession. This is a fully assembled with Raspberry Pi 4 or 5 4GB and tested. It includes 128GB MicroSD card (pre-programmed with Ubo App), power adaptor

The price is high because these are handmade units right now and there's a lot of logistics overhead.

I prefer to focus on the foundation code architecture instead of dealing with cumbersome logistics of shipping small number of units at his moment.

I would hope that these units would have premium collector value since it comes with a certificate of authenticity and unique touches.

If you want not in a big rush and would appreciate a good discount (20~40%+), make a $1 reservation to be notified when there is general availability. I will ship out the reserved items based on the reservation number.
