• Previously, we wrote about theLouder Raspberry Pi,an open-source media center that integrates the Louder Raspberry Hat based on a 25W TAS5805M Class-D amplifier. • Now, the developer has introduced theLouder Raspberry Hat Plus, upgrading from the TAS5805M amplifier to the more powerful TAS5825M, capable of driving up to 53W in mono (PBTL) mode while offering improved efficiency and thermal performance. • The Louder Raspberry Hat Plus is compatible with all Raspberry Pi models and comes in 1X and 2X variants. • The 1X version delivers up to 2×32W at 8Ω or 2×45W at 4Ω, the 2X version, on the other hand, supports 2×32W plus a dedicated 53W subwoofer channel, with bridge mode available for higher mono output. • The board also integrates a DSP with 15-band parametric EQ per channel, 128-tap FIR filtering, 3-band DRC, selectable LF/HF crossovers, digital volume and gain control (32-step analog gain), selectable modulation schemes, adjustable switching frequencies up to 768kHz, and hardware fault monitoring for overcurrent, thermal, and power supply conditions. • The board can be powered from a 7V-26V external power input (up to 28V max) and includes an onboard step-down regulator to supply 5V to the Raspberry Pi.
