PT datasheet MS datasheet A couple of screen captures from the datasheet: Audio does’nt go throu PT I’m currently implementing several of the changes you propose and will post updated files later.

PT Datasheet, PDF – Alldatasheet

Long tracks can pickup noise a lot easier. Since this is a simple design, the board you have designed should work, but I would like to point out things that vatasheet save you from having troubles in more complicated designs. Keep signal tracks as short as possible. They might lead to EMI problems. I bought a Pt chip, I have build the board but I can’t write the sketch.

PT audio processor PCB

I hope the choices I have made does not degrade the audio quality noticeably and is still “safe” enough. Otherwise when soldering in the oven, the solder will be sucked by via.

There must be at least some solder mask between them.

Some additional guidelines for a good PCB design: Also it will affect datazheet impedance of transmission lines. I finalized the updates and tried to implement as many of the suggestions as possible without total rerouting.

Write some sketch with some instructions and send to Arduino volume,channel, etc. Also it acts as additional power supply when short pulses of current are needed for the IC.

Thanks for the great feedback VaidasZ! Does someone have some datsaheet of sketch? This is mainly to be able to create an even more compact module but it means that I have left out the input surge protection resistors in the PT example.

I have made a PCB with Fritzing and I would really appreciate it if you could help me with a “sanity check” of my design and component selection.

The schematic is not my proudest moment I focused my attention on the PCB PT audio processor PCB. For every dtaasheet input pin of the IC especially digital IC’s you must place a bypass capacitor a capacitor from Vcc,Vdd, Luckily these are only minor problems.

You definitely don’t want that. Some homemade uses of the PT This capacitor is needed to filter out the noise coming from and going back to power supply rail.

Hi, please can you put your code here. Thank you, Best regards. Try to keep track widths and corners consistent – this makes the board look better; Avoid 90 degrees corners on the PCB tracks. I have also included a few photos of commercial implementations of the PT for reference: Vias must be apart from component pads.


For this reason I would suggest placing components in different way. I’m experiencing some strange drawing bugs in Fritzing, some of them can be seen in the schematic file and on the IC labeling. I put PT on it with others elements.

Otherwise you will have a digital noise in your analog circuitry, it can even cause parasitic oscillations. This might lead to arcing in high voltage circuits, increase EMI radiation in high dagasheet and power circuits.

As in the pictures you have attached, all capacitors should be close to the pins of IC. Most of the audio paths are short, exept for the two audio channels that needs to cross the IC due to the IC’s pinout. I bought a pair of 3w 4ohm USB speakers that I intend to gut and use. Please let daatsheet know your experiences with these ICs. From GitHub download library PT This might lead to noisy analog signal and even parasitic oscillations. Please share PT example arduino code.
