Bringing audio to your projects
The Pimoroni Speaker pHAT is an add-on board for Raspberry Pi, which features an on-board DAC and 3W mono amplifier, and a tiny but effective 8Ω 2W Myler speaker. The amplifier sums both audio channels out to the single speaker, and the board has routed holes to channel the sound. This makes sure the pHAT delivers the best sound output from its 2W system.

Code a custom sound level
The Speaker pHAT features a bar graph of 10 bright white LEDs which uses the SN3218 LED driver chip. These LEDs are codable to suit whatever project you are working on, but the supplied installer has a custom plugin which displays sound level on the LEDs bar graph. You may decide to configure the bar graph for sound-to-light shows as a feature on your Raspberry Pi or have the LEDs triggered by sound notifications. The LED bar graph is an excellent feature which adds a little light to any Raspberry Pi audio venture.

Compatible with all 40-pin GPIO Raspberry Pi boards
Although the Pimoroni Speaker pHAT was created with the format of the Raspberry Pi Zero in mind, this add-on board is compatible with any Raspberry Pi variant that has 40-pin GPIO. The Pimoroni Speaker pHAT comes as a kit, so board assembly and soldering of the Myler speaker and the female header onto the pHAT is required. Entire assembly of this add-on board will take approximately 30 minutes. Setup and function of the Speaker pHAT uses only five of the GPIO pins, leaving plenty of room to connect different components and expand your projects.
