1. Required Parts

Not only will you need parts for the DIVE COMPUTER but also for easy development. Such items will be marked as an option.

1.1. Micro:bit

Micro:bit is the heart of the platform. You must purchase version 2.x or higher. This is important because there is not enough memory for bluetooth to work properly on earlier versions. For debugging it is more convenient to take a version with a block of replaceable batteries. This one suited us.
