Both variants for Louder Raspberry Hat Plus – 2.0 and 2.1 are now available at Elecrow, my official production and fulfillment partner
This would be especially useful to folks in the US, since delivery from the EU is now really expensive with UPS – not only do they charge $40 for shipping, but also an extra charge for import handling ($12), and they collect the Trump tariff, despite the US Supreme Court ruling out that they reference on their own website. At least they would not go out of business anytime soon, we can be assured.
Anyway, boards are based on TAS5825M DAC with powerful DSP, which can be used with a custom driver developed by me. It allows you to flexibly configure EQ and filters for each channel, and for the 2.1 model, specifically set the cutoff frequency and gain for the subwoofer channel.
Started as a small experiment with Raspberry Pi, it will be a base for upcoming ESP23-based dual DAC boards, starting with Dual DAC Audio Brick and Louder Esparagus Dual DAC.
At the same time, a slightly lower-powered Louder Raspberry Hat is available in a single DAC variant at Elecrow, while the dual DAC should be available in 2-3 weeks.
