LORDWORLD WM8960 Audio HAT development board

SKU CH-N2N3-MNG8B

Adds stereo audio with dual MEMS microphones, a 3.5 mm headphone jack and speaker outputs to Raspberry Pi boards via the 40-pin header

  • Hi-Fi stereo playback with WM8960 low-power CODEC
  • Dual MEMS microphones enable left and right channel recording
  • I2S interface connects cleanly to Raspberry Pi 40-pin GPIO
  • 5 mm headphone jack plus dual speaker terminals for flexible audio output
  • Python demo code and manual included for rapid development

Target use

The LORDWORLD WM8960 Audio HAT is a development board that adds high-fidelity audio input and output to Raspberry Pi single-board computers. It is intended for makers, students and engineers building voice-controlled devices, portable recorders or custom media players.

Connectors and build

The board mounts directly onto the 40-pin GPIO header and exposes a 3.5 mm headphone jack plus a dual-channel speaker terminal block. Dual onboard MEMS microphones capture stereo audio while the WM8960 codec handles playback and recording through the I2S bus.

Thermals and power

The low-power stereo codec draws minimal current from the Pi supply, so the host board’s existing cooling is sufficient. No active cooling or external power adapter is required and the module adds no audible noise during normal operation.

Perguntas sobre este artigo

Does the I2S interface on the WM8960 HAT cap the sample rate or bit depth in practice?

The WM8960 codec handles stereo playback and recording through the I2S link; the practical limits are those defined by the codec itself rather than the bus.

What physical clearance does the 40PIN GPIO header and the 3.5 mm jack need on the Raspberry Pi?

The board sits on the standard 40PIN GPIO extension header and adds a 3.5 mm earphone jack plus dual speaker terminals, so allow height for the jack and side space for speaker wires.

Which step in the Python demo do users most often miss when setting up playback or recording?

Many forget to enable the I2S overlay in config.txt before running the supplied Python scripts for play and record.
