Play high quality, LOUD audio from your Pimoroni Yukon project, with this mono 25W Class-D amplifier.

You can use this amp to drive 4Ω (or greater) speakers with up to 25W of power (depending on the input voltage provided to the Yukon host). We've tried it with some disturbingly large ones and it can really pack a punch!

Speakers are sold separately.

Features:

TAS2780 DAC / amplifier chip (datasheet)
Mono 25W audio out via 5mm pitch screw terminal
For 4 ohm or greater speakers
Temperature sensor
Fully-assembled (no soldering required)
Compatible with Pimoroni Yukon

Software

We've added some examples that show you how to play a wav file or play tones using MicroPython's I2S functionality (so you can teach your robot to scream with a machine or human voice).

Notes

Measurements: 24mm x 20mm x 15.3mm (L x W x H).
This module makes use of MicroPython's I2S system to drive the amplifier. Currently this system only supports two instances at any one time, meaning only two modules can be used simultaneously.

About Yukon

Yukon is a high-power modular robotics and engineering platform, built around Raspberry Pi's formidable RP2040 chip. It has slots for attaching interchangeable hardware modules for driving combinations of devices such as motors, servos, steppers, and LED strips, all from one board!

Featuring an XT30 connector, Yukon can be directly powered off 2 to 4 cell LiPo batteries (or any other 5 to 17V source), to deliver up to 15A continuous for your high-power projects. An e-Fuse with switchable output protects the board, along with voltage, current, and temperature sensors that can be monitored by your programs.
