PT2314 Sound Quality Adjustment Module Voice Module IIC 6V-10V Audio Processing Module for Arduino
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. PT datasheet MS datasheet A couple of screen captures from the datasheet: From GitHub download library PT I finalized the updates and tried to implement as many of the suggestions as possible without total rerouting.
From electrical point of view: You definitely don’t want that. I bought a pair of 3w 4ohm USB pt22314 that I intend to gut and use.
Otherwise when soldering in the oven, the solder will be sucked by via. This might lead to noisy analog signal and even parasitic oscillations. Thanks for the great feedback VaidasZ!
This might lead to arcing in high voltage circuits, increase EMI radiation in high speed and power circuits. Also it will affect the impedance of transmission lines. As in the pictures you have attached, all capacitors should be close to the pins of IC. I have opted for resistors and ceramic capacitors and a couple of ceramic capacitors. Otherwise you will have a digital noise in your analog circuitry, it can even cause parasitic oscillations.
10 Pcs Pt2314l Sop-28 PT2314 SMD Channel Input Audio Processor
Ppt2314 sure your analog and digital grounds are tp2314 only at one point. Write some sketch with some instructions and send to Arduino volume,channel, etc. 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. Vias must be apart from component pads.
I bought a Pt chip, I have build the board but I can’t write the sketch.
Audio does’nt go throu PT Does someone have some example of sketch? Try to keep track widths and corners consistent – this makes the board look better; Avoid 90 degrees corners on the PCB tracks.
I hope the choices I have made does not degrade the audio quality noticeably and is still “safe” enough. I put PT on it with others elements. Thank you, Best regards. I built PCB using application circuit from datasheet. For every power input pin of the IC especially digital IC’s you must place a bypass capacitor a capacitor from Vcc,Vdd, Keep signal tracks as short as possible. Long tracks can pickup noise a lot easier. This capacitor is needed to filter out py2314 noise coming from and going back to power supply rail.
The schematic is not my proudest moment I focused my attention on the PCB They might lead to EMI problems.
Some homemade uses of the PT Hi, please can you put your code here. For this reason I would suggest placing components in different way. PT audio processor PCB. I have also included a few photos of commercial implementations of the PT for reference: I have made a PCB with Fritzing and I would really appreciate it if you could help me with ppt2314 “sanity check” of my design and component selection.
Luckily these are only minor problems. There must be at least some solder mask between them. 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.
Please share PT example arduino code.
PT audio processor PCB
I have no prior PCB designing experience and my electronics knowledge is basic. I’m currently implementing several of the changes you propose and will post updated pr2314 later. I’m experiencing some strange drawing bugs in Fritzing, some of them can be seen in the schematic file and on the IC labeling.
Some additional guidelines for a good PCB design: Also it acts as additional power supply when p2t314 pulses of current are needed for the IC. Also, make sure that all your digital and analog signal grounds have different paths until they meet the IC. Please let us know your experiences with these ICs.
