New version of the I-Sabre TCXO, its architecture is designed to allow you to have all outputs on the same side when the Raspberry Pi is coupled to the DAC. Connectors have been added to make the integration of the various components of a DIY player as simple as possible.

I-Sabre is now equipped with an advanced power management (ATX type) for the clean shutdown of the software solution used. These functions are managed by a PIC and allow different shutdown modes according to the needs (software or hardware).

This converter with new features is ideal for turning a Raspberry Pi 2.0, A+ or B+ into a high-definition file reader. Equipped with the famous Sabre ES9023, a revised schematic, and OS-CON capacitors, this DAC will give you a musical, dynamic sound rich in micro details.

Intended for the many software solutions dedicated to audio playback on this platform, it allows an easier than ever implementation for an incomparable result in this price range.

Key Functions :

• I2C port.
• Simplified assembly (no welding required).
• Low noise control with heatsink.
• Integrated on/off/boot management.
• Dedicated connector for screen connection (direct pinout HD44780).
• Dedicated push button connector (momentary).
• DC 5.5/2.1mm jack input on the PCB.
• Optimization of the integration of the converter and the circuit.
• Advanced power management.
• Low noise regulation of the power supply allowing a maximum power supply of 7.5VDC (2A).
• Feeding the Raspberry Pi via the GPIO, feeding the Pi separately is no longer necessary.
• PCM analog/digital conversion (24bit 192kHz max).
• 2Vrms stereo analog RCA output.
