MA12070P + ESP32 Raspberry Pi Power Amplifier Board – I2S / IIS Input

Take your Raspberry Pi audio setup to the next level with this high-performance MA12070P + ESP32 Power Amplifier Board. Designed to attach directly to your Raspberry Pi Zero, 3, or 4B via the standard 40-pin 2.54mm header, it delivers a powerful 2 × 80W audio output with crisp, high-quality sound — all in a compact form factor that matches the width of the Raspberry Pi 4B.

Key Features

Broad Raspberry Pi Compatibility: Supports Raspberry Pi Zero, 3, 4B, and other models with a standard 40-pin 2.54mm straight-needle insertion header.
2 × 80W High-Quality Audio: Configure your Raspberry Pi to output an IIS/I2S audio signal to drive the Infineon MA12070P amplifier chip for powerful, clear stereo sound.
Flexible Power Input: Compatible with a USB PD adapter or a 24V DC power supply. When using a PD adapter via a Type-C connection, the module automatically negotiates 20V PD output, then uses an onboard DC-DC converter to also power your Raspberry Pi — no separate power supply needed.
ESP32 Backplane Option: Available in two variants — Raspberry Pi port or ESP32 backplane — for flexible integration into your project.
Simplified Wiring: Single-cable power solution reduces clutter and simplifies your setup significantly.
Open-Source Driver Support: Driver support for the Infineon MA12070P is available on GitHub. (Note: Additional detailed software support beyond the driver profile is not included.)

Frequently Asked Questions

Q: Which Raspberry Pi models are compatible with this MA12070P ESP32 Power Amplifier Board?

A: This amplifier board is compatible with Raspberry Pi Zero, 3, 4B, and other models that feature the standard 40-pin 2.54mm GPIO header. The board's mounting holes and physical dimensions are aligned to match the Raspberry Pi 4B for a clean, secure fit.

Q: Does the MA12070P amplifier board require a separate power supply for the Raspberry Pi?

A: No — when using a USB PD adapter via the Type-C port, the onboard DC-DC converter automatically powers the Raspberry Pi as well. This eliminates the need for a separate power cable for your Pi, simplifying your wiring considerably. Alternatively, a 24V DC power supply can also be used.

Q: Where can I find drivers for the Infineon MA12070P chip used on this board?

A: The driver for the Infineon MA12070P is publicly available on GitHub under the Infineon MA12070P driver profile. Please note that additional detailed software support beyond the publicly available driver is not included with this module.

Q: What is the difference between the Raspberry Pi Port and ESP32 Backplane variants?

A: The Raspberry Pi Port variant is designed to plug directly into a Raspberry Pi's 40-pin header, while the ESP32 Backplane variant is intended for use with an ESP32 microcontroller. Choose the version that matches your development platform and project requirements.
