SunFounder Launches Fusion HAT+ For Raspberry Pi

SunFounder released the Fusion HAT+ Raspberry Pi expansion board, and a reviewer tested it on a Raspberry Pi 5 in January 2026. The HAT+ provides microphone, speaker, PWM/servo/motor drivers, ADCs, a rechargeable battery, and supports TTS/STT with local and cloud LLMs, but requires its battery connected and proper USB-C charging to avoid I2C communication failures. The review covers assembly, audio setup, and debugging.
