The FM receiver module is based on the TEA5767 [1, 2] chip. It is a well-known module that could be controlled via the I2C bus. It covers the FM frequency range from 76MHz to 108MHz. At the output, it ...
In our surface-mount age, it’s easy to be jaded about miniaturization. We pretty much expect every circuit to be dimensionally optimized, something that’s easy to do when SMDs that rival grains of ...
