Yes!Unless I'm mistaken, he has the skinniest deployment altimeter you can buy. Good products. Also if you really want to make your own from scratch he has documented boards, components, code, and everything else on github.

I believe that those offerings with "Duo" in the model designation are dual-deploy...Are they a dual deploy?
Are they a dual deploy?
Is that a yes or no?All the features of their products are detailed on the website shown in post 1.
The Uno is single deploy and Duo is dual deploy.Is that a yes or no?
Ken, What battery are you using for the Duo?Heres the board for the Eggtimer Quark on the left compared to the Micro Alti Duo on the right. Quark is just shy of 18mm wide, the Duo board is 15mm wide screw terminals bring it to 17 but it still easily fits in an 18mm body tube!
I'll have to check, it came with a 1s cell, long and skinny. I'll post details tonightKen, What battery are you using for the Duo?
Thank you all for the nice comments I am having fun developing those and would like to thanks people that have bought boards because it has allow me to invest and continuously improve them. I got the Kalman filter from Cris (@Cerving eggtimer rocketry who also does some affordable and reliable Arduino based altimeters) . The idea is and has always be to be able to have affordable altimeters especially for people living in Europe because it is expensive to import US altimeters.I have an altiduo mini. Bought it as a kit over 7 or 8 years ago. Harder to put together than an eggtimer. It’s so small, to program it, you have to remove the chip, there is no usb, or manual programming on the mini at all. Loved the fact the software is on GitHub, I learned a lot from his code, it is very, very well documented and structured. I think it was the first time I had seen a working Kalman filter outside of a textbook.
