Attempt at understanding how CITAQ H10-3 works and is an exploration log of how the SDK and device work because in the future I may want to give a shot at writing an app for it. This doesn't quite fit into the above repository as it is more general notes and timeline of discoveries I found while exploring it and is a bit more disorganized (but is eventually cleaned up and entered into the repository). Still there are other useful notes that cannot be easily transferred and so may be of use to anyone still exploring this device as well so enjoy!

Creating an FM display to show a log of the Radio Data System (RDS) signal included in broadcast FM stations using the RDA5807M chip, which has RDS decoding capability baked into the device. Despite the lack of documentation for the cheap radio module (PCB model RRD-102 V2.0), the pinout has been traced out using the datasheet. The resulting pinout is provided, along with a note about the device being a 3.0V device and requiring appropriate VCC input. Future plans involve communicating with the module.
