Companies optimize SD Cards for price or performance which leads to different grades of SD Cards. We will discuss why different SD Card grades exist, what grades can be distinguished and why they are important. This post is the final part of a three…

Hence to understand why SD Card quality is not always the same we need to know how flash memory is manufactured and how it works. This post is part of a three part mini series about SD Cards with some in depth information. Content…

The RP2040 has two I2C controllers – good for example, when you want to run two I2C devices with the same I2C address. In my test setup, I have an Adafruit Feather RP2040 microcontroller board,…
