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.

They might lead to EMI problems. I have no prior PCB designing experience and my electronics knowledge is basic. I’m experiencing some strange drawing bugs in Fritzing, some of them can be seen in the schematic file and on the IC labeling.
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. There must be at least some solder mask between them.

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 ptt2314 use.
Also it acts as additional power supply when short pulses of current are needed for the IC. 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. Please let us know your experiences with these ICs.
I have also pr2314 a few photos of commercial implementations of the PT for reference: Thanks for the great feedback VaidasZ! Does someone have some example of sketch? I built PCB using application circuit from datasheet.

Otherwise when soldering in the oven, the solder will be sucked by via. From electrical point of view: From GitHub download library PT For every power input pin of the IC especially digital IC’s you must place a bypass capacitor a pg2314 from Vcc,Vdd, PT datasheet MS datasheet A couple of screen captures from the datasheet: I finalized the updates and tried to implement as many of the suggestions as possible without pt314 rerouting.
Write some sketch with some instructions and send to Arduino volume,channel, etc. Also, make sure that all your pt234 and analog signal grounds have different paths until they meet the IC.
Hi, please can you put your code here. Audio does’nt go throu PT Some additional guidelines for a good PCB design: Please share PT example arduino code. Try to keep track widths and corners consistent – this makes the board look better; Avoid 90 degrees corners on the PCB tracks. Luckily these are only ph2314 problems.
This might lead to arcing in high voltage pf2314, increase EMI radiation in high speed and power circuits. As in the pictures you have attached, all capacitors should be close to the pins of IC. This might lead to noisy analog signal and even parasitic oscillations.
Also it will affect the impedance of transmission lines. Keep signal tracks as short as possible.
