I ordered a Marsa 33 w/LCD a couple of weeks ago and was curious if anyone had experience with them recently. Not stressing over it, just trying to set expectations. Thanks!
Marsa33's orders are shipping now.
Marsa33 new production was held up a bit due to a quality issue from the PCB supplier. Marsa33's orders are shipping now.
Are the MarsaNet Pyro boards available?
Ken, I will set a goal to update the pathetic website this weekend.
Got my 33 today:

Now I gotta find the instructions. Nice procedure to cut the size down, put the LCD on a plug-in unit. Kurt Savegnago
Yup, Gotta got to see if there's a manual out for it yet. I just got done rooting a phone. Kurt

Operation same as Marsa54L. Manual online. Plug LCD with 6pin on the PCB, 2pins on LCD off the board to the right....
John, out of curiosity, what are the two pins for?
John, looking a using the Marsa for a 100K’+ flight. Does the Kalman mode use both the Baro and Accelerometer to do that? We want to rely on the acceleratometer only to sense apogee, since baros don’t work well at those altitudes. Will the Marsa33 work for this application? Thanks!
For a 100K flight the "Accel" only mode is best, at those altitudes the Kalman filter is disregarding the baro only so just cut out the "middleman" and use the accelerometer integrator (its pretty good).
However if you have some time before the flight (BALLS?) contact me and I can do some custom firmware for you that uses Kalman until the baro poops out then switches to acceleration integration. So instead of accumulating integration error from the ground we start the integration from ~50K feet for a better result. I am doing something similar for another customer that has a very extreme flight coming up.
