Data logging on Trinket Pro 5V

Post by BlazingAngel665 »

I am working on a rocketry project, at the heart of which is the wonderfully compact, delightfully low budget Trinket Pro. I am using a barometric altimeter (BMP085 GY-65) and GPS board (V3) to track the progress of the flight. The problem I am running into is, how do I store the data. There is a shield for the Uno, but it is too large for this project. The GPS chip has onboard data logging every 15s, which is hardly the resolution I need for the launch, which might be over in 15s. Is there a way to accelerate onboard data logging? Is there a way to write the barometer data to the same location as well? Or baring that best case option, what else can I do to store data off the trinket?
Thanks for your help!

There is EEPROM, but that is just 1K, so you can't log much data.

The Micro-SD breakout board might be your best option:

Also check out https://www.adafruit.com/products/1895 not sure how much data you can get in 15 sec's but you can add few more for just in case..
