At the time of this design, the website of the RDA microelectronics is not accessible from my location. Because of this reason, I download different versions of RDA5807M datasheets from the internet. While going-through those datasheets, I observed that it comes with limited information. Finally, I decided to build this receiver to verify some of those parameters and to review the RDS functionality of the chip.
At the testing stages, this receiver decodes RDS signals from all the FM station including weak stations. “RanOne FM” is the most attractive station name which I captured from this receiver. This station transmits its name in an animated style and its display on the receiver’s LCD without any problems.
The circuit diagram, PCB designs and firmware source code of this receiver are available under MIT and CC-4 licenses at github.com. You can read the full blog post here.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
