Revised version 2, this version incorporates a batch of new options:

  • Simplified assembly (no welding required).
  • Low Noise Control with Heat Sink
  • Integrated ignition-extinction-reboot management
  • Connector dedicated to a screen connection (Direct Pinout HD44780)
  • Dedicated push-button connector (momentary)
  • Input Jack DC 5.5 / 2.1 on the PCB
  • Optimization of the integration of the converter and the circuit.

Product description:

New version of the TCXO I-Saber, its architecture is designed to allow you to have all the 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 reader as simple as possible.

The V3.0 is now equipped with an advanced power management (ATX type) intended for the proper extinction of the software solution used.
These functions are managed by a PIC and allow different extinction modes depending on the needs (software or hardware).

This converter with unprecedented functions is ideal for transforming a Raspberry Pi 2.0, A + or B + into a high-definition file player.
Equipped with the famous SABER ES9023, a schematic revised, and capacitors OS-CON this DAC will offer you a soundmusical, dynamic and rich in micro details.

Aimed at the many software solutions dedicated to audio playback on this platform, it allows a simpler implementation than ever before for an incomparable result in this price range.

AAluminum housing specially designed to receive the Pi 2 / Pi 3, the converter and display is also available.

Here is a test in English (with French subtitles) of Hans Beekhuyzen


Features:/ Strong>

Supplied with 4 nuts, 4 screws and 4 spacers M2.5 to fix it on the PI B +, A + or 2.0 (HAT format)

The LED display and button are sold separately.

Details on how power management works:

Ignition process:

Push the button
The DAC switches on the PI, the LED flashes while waiting for the "BOOT OK" signal from the PI (GPIO 22)
This signal happens because there is a script that changes the state of the spindle once the pi is started.
Once the signal is received, the led stays on, and the system is in a stable state.

Extinction from the button:

Push the button.
The microcontroller detects the extinguishing order
It sends a "Shutdown" signal on GPIO 17 to launch the extinction script
Once the PI is switched off, the button goes out and waits for a new light.

Extinction from Volumio:

Click on "Power OFF"
The Pi sends a "Shutdown" signal on GPIO 4 to launch the extinction script
Once the PI is switched off, the button goes out and waits for a new light.

Reboot from Volumio:

Click on "Reboot"
The Pi sends a "Reboot" signal to GPIO 4 to start the restart script
Once the PI is restarted, the Boot OK returns and the led of the button is fixed.

Although optimized to work with the script available in the forum, power management works by default in hardware mode without having to modify the audio solution retained.

Here is a schematic diagram of connecting from one terminal to another to "shunter" the microcontroller. It is therefore necessary to remove the AT Tiny85 microcontroller from the circuit as indicated.
In this case it will be necessary to use a switch (permanent contact) to keep the Raspberry Pi on.

Impressionnant !
Testé sur un ampli à tube haut de gamme avec l'album Companion de Patricia Barber. Impressionnat de réalisme et de rapport qualité prix. Je partage le point de vu du client anglophone sur la séparation des instruments. Quand on voit le prix de la carte et du Pi, ça laisse songeur. A atomisé un autre DAC achété aussi chez Audiophonics à 749€. Testé uniquement en liaison Wifi. L'autre DAC utilisait un récepteur WXC50 de Yamaha, ce qui peut jouer.
Même si la puce ES9023 est sensé être moins haut de gamme que la ES9018 ou ES9028, je pense que le fait que ce soit une chip tout en un fait que Esstech a fait un sans faute sur la couplage numérique analogique et au final le son est bluffant. Vu que le Rasptouch est basé sur cette même carte, pour ceux qui sont pas bricoleur, ça fait un DAC exceptionnel à 349€ avec écran tactile en plus. Bluffé...

Amazig product
After having SONOS im my home for years, for pure curiosity, I assembled Pi3 with Hifiberry DAC + Pro and find that SONOS world means that you go around with cotton in your ears. Being curious, I found a apropriate box for my new mediaplayer on Audiophonics home page but then I saw I-Sabre V3 DAC. There is no way to compare I-Sabre with Hifiberry, let alone SONOS. I-Sabre makes my Naim sing, with lots of micro details and broad and wide sound stage. It's possible to point out where musicians stands, allmost as it was live and me looking at. I just purchased another I-Sabre, it's realy difficult to find a DAC for that price and that audio quality. Good work, Audiophonics, for bringing us this little gem.
