• Weekend project – RDA5807 FM Radio

    Putting a bunch of used stuff together to build a FM radio. This build remembers me how complicated was, build a FM Radio in the old days. Lots of coils, transistors, ceramic filters, a CA1310 as stereo decoder. Today we have all in one single chip and surprisingly no coils. To control this module, I chose a 8bit microcontroller (more would be a waste and I had a PIC18F2520). A classical 24C512 eeprom because its a I2C device and I don’t have pins enough for a SPI. To give it a better looking, I used an old and forgotten  LCD. During the design, I put a DS1307 (rtc) but at the end, I did not find one in my stuff. If you want to build one, please take a look on my GitHub repository:
