Q17 is an amplifier based on the QUAD 405 current dumping principle.
Please refer to Q17 Project description from Tiberiu Vicol’s original design.
Q17-Turbo project (200W @ 8 Ohms):
The natural evolution of the Q17-Mini, this time with two pairs of power transistors, better thermal management with the same technical characteristics and the same sound signature.

With the squeezelite-esp32 software, you can

- Stream from LMS and send audio to the build-in amplifier, the line-out jack, the spdif connector or another Bluetooth speaker. You can also use an external I2S DAC if you connect it to the general purpose 5/8 pins connector and tweak the software. Synchronization works.
- Stream from a Bluetooth device and send audio to the same outputs, except of course for sending to another Bluetooth speaker … There is no guarantee of audio/video synchronization at this point
- Stream from an AirPlay1 device (iPhone, iTunes …) to the same outputs, including to a Bluetooth speaker. Synchronization works.
- Add your own buttons, rotary encoder and map/combine them to various functions (play, pause, volume, next …
- Use IR control by adding a simple receiver compatible with 38kHz device (no pullup resistor or capacitor needed)
- Add a display like this one which can be directly connected to the 6-pins header. Currently SH1106, SSD1306, SSD1322, SSD1326/7, SSD1351, ST7735 and ST7789 displays are supported.
