Raspberry Pi 40-pin audio HAT

The LORDWORLD DA7212 is an I2S audio HAT that connects to the Raspberry Pi 40-pin GPIO header and provides stereo input and output for voice capture, audio experiments and interactive prototypes. It is aimed at makers and developers who need a compact add-on with integrated microphones and multiple analogue interfaces.

Installation notes and common issues

The board mounts directly on the 40-pin header and the onboard EEPROM enables automatic driver loading in Raspberry Pi OS, so no manual device-tree editing is required for basic operation. A programmable button and status indicators are available for custom functions. Misaligned header pins or an incomplete GPIO connection are the most frequent causes of the codec not being detected.

Pre-order checklist

Confirm that your Raspberry Pi model exposes the standard 40-pin GPIO header and that you are running a Raspberry Pi OS release with I2S support. You will need either a 3.5 mm headphone plug, an AUX source, or speakers wired to the screw terminal or PH2.0 header to use the analogue outputs. No separate microphone hardware is required because dual microphones are already on the board.

Questions about this item

How do I verify the DA7212 HAT is working after connecting it to the 40-pin GPIO header?

Check Raspberry Pi OS sound settings for the DA7212 device, play a test tone through the 3.5mm jack or speaker terminals, and record using the dual microphones to confirm 24-bit 96kHz capture and playback.

What comes in the box and what must I buy separately for the DA7212 audio board?

The board includes dual microphones, 3.5mm headphone jack, AUX input, speaker screw terminal, PH2.0 speaker header, EEPROM, button and indicators; you supply a Raspberry Pi with 40-pin GPIO and speakers or headphones.

Which version of the LORDWORLD DA7212 I2S Audio HAT should I choose for my project?

This single model supports up to 24-bit 96kHz stereo via I2S and I2C control, with dual microphones, headphone, AUX and speaker outputs — select it when you need all those interfaces on one HAT.
