Tempo Semiconductor TSCS42xx Audio HAT Board for Raspberry Pi®
Tempo Semiconductor TSCS42xx Audio HAT Board for Raspberry Pi®
Tempo Semiconductor TSCS42xx Audio HAT Board transforms the Raspberry Pi into a customizable audio solution for a variety of applications. The TSCS42xx has an integrated DSP that is easily adjustable using the TSCS42xx ALSA GUI and flash savable. Optional support for OLED display panel enables a completely "plug-and-play" stand-alone operation without a need to connect a monitor, mouse, keyboard, USB flash disk, Bluetooth, Wi-Fi or Ethernet cable.
A few of the possible use-cases for the TSCS42xx Audio Codec HAT when combined with a Raspberry Pi:
● Wired or Wireless multi-room streaming audio player / “Smart Speaker” / Voice Activated Assitant
● Mini Soundbar for placement above or below computer monitors
● Arcade table project with high quality, immersive audio
● Internet radio player with high quality stereo audio
● Gaming Headphone Amplifier
