Flipper-Zero

Today I used prototype boards I purchased with my Flipper Zero pre-order for the first time. I think I didn’t use them before (and I have Flipper for over 6 months) because the single purpose for them that was repeated over and over again was to expand a device with Wi-Fi or general-purpose 2.4GHz radio, which never appealed to me. However, recently, I found a category of FlipperOS applications that’s quite obvious - I2C interfaces, for example for light or temperature sensors. This quickly rendered my previous attempts at creating such a self-contained portable I2C client from scratch obsolete and demanded the soldering iron to be turned on.
