From electrical point of view: Some additional guidelines for a good PCB design: PT datasheet MS datasheet A couple of screen captures from the datasheet: 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.
Otherwise you will have a digital noise in your analog circuitry, it can even cause parasitic oscillations. Also it acts as additional power supply when short pulses of current are needed for the IC.
Otherwise when soldering in the oven, the solder will be sucked by via. I bought a Pt chip, I have build the board but I can’t write the sketch. I bought a pair of 3w 4ohm USB speakers that I intend to gut and use. For this reason I would suggest placing components in different way. As in the pictures you have attached, all capacitors should be close to the pins of IC.
They might lead to EMI problems. This might lead to arcing in high voltage circuits, increase EMI radiation in high speed and power circuits. Please let us know your experiences with these ICs.
Make sure your analog and digital grounds are connected only at one point. Vias must be apart from component pads. For every power input pin of the IC especially digital IC’s you must place a bypass capacitor a capacitor from Vcc,Vdd, Some homemade uses of the PT You definitely don’t want that. From GitHub download library PT Thanks for dwtasheet great feedback VaidasZ! Long tracks can pickup noise a lot easier. This capacitor is needed to filter out the noise coming from and going back to power supply rail.
Also, make sure that vatasheet your digital and analog signal grounds have different paths until they meet the IC. Also it will affect the impedance of transmission lines.
Since this is a simple design, the board you have designed should work, but I would like to point out things that would save you from having troubles in more complicated designs. 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 put PT on it with others elements. Pt2134 have no prior PCB designing experience and my electronics knowledge is basic. I hope the choices Xatasheet have made does not degrade the audio quality noticeably and is still “safe” enough.

Hi, please can you put your code here. I have also included a few photos of commercial implementations of the PT for reference: Does someone have some example of sketch? 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’m experiencing some strange drawing bugs in Fritzing, some of them datasheeet be seen in the schematic file and on the IC labeling. I’m currently implementing several of the changes you propose and will post updated files later. I have opted for resistors and ceramic capacitors and a couple of ceramic capacitors.
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 built PCB using application circuit from datasheet. The schematic is not my proudest moment I focused my attention on the PCB Write some sketch with some instructions and send to Arduino volume,channel, etc.
This might dwtasheet to noisy analog signal and even parasitic oscillations. Please share PT example arduino code. Audio does’nt go throu PT PT audio processor PCB.
There must ph2314 at least some solder mask between them. I finalized the updates and tried to implement as many of the suggestions as possible without total rerouting.
