Description
Description
A small 2.8" x 1.7" (71 x 43mm) amplifier board based on TEA2025 amplifier chip. Can be used as stand alone amplifier for small projects. Pair of jumpers will switch from stereo to bridge mode
Need for it was to use it as stackable amplifier for our 4 channel mixer
The amp can run on 3 to 15V power source.
