Arduino tutorials are a great resource for building your own microcontroller projects. A cheap arduino Nano clone with a 10DOF sensor should give you almost everything you need in terms of hardware, for around $20 total. (Note: I do not endorse these specific products, nor have I verified they work together. This is just an example). Alternatively you can get a full starter kit that contains a wider assortment of useful sensors and actuators to really learn the broader arduino framework. Buying a starter kit like this and following a full set of associated tutorials is probably the better route for a beginner like you to follow, rather than diving straight into the end-goal project you are describing here. The Arudino community is huge and has countless great learning resources, including the guides on the official Aruino site.

The multirotor community also has a lot of great options like ardupilot if you'd rather start from an established codebase instead of building everything from scratch. Flight controllers often contain a fairly comprehensive suite of sensors and features like data logging that are perfect for a rocket flight controller, even if they usually don't expect to be crammed into and flown as a rocket. There are also plenty of flight controllers outside of the arduino environment, though many of these are intended to be more of an out-of-the-box solution for mutirotor or RC aircraft hobbyists, so their adaptability for use in rocketry may be more limited.

the EEPROM was extremely hot. the Arduino was smelling a lot, is not turning at all! that sucks, I already ordered one from Amazon. I got this one: https://www.amazon.com/gp/product/B00NLAMS9C/
