ZK-502H Bluetooth 5.0 Stereo Amplifier Board – Up to 2 × 50W
Add wireless audio to your DIY stereo speaker project with the ZK-502H amplifier board. Connect through Bluetooth 5.0 or AUX to build a compact two-channel audio setup around the TPA3116D2 amplifier chip.
This is an amplifier board for a DIY build, not a complete speaker system. Actual output depends on power supply capacity, speaker load and audio input; the listed maximum is not a guaranteed continuous output rating. Confirm the required supply current, supported speaker impedance and wiring using the model-specific manufacturer documentation before connection. Use a compatible DC supply within the stated voltage range.
