Audio Sampling Rate Display Module I2S LRCK Interface
 

 

 

 



Product Name:Universal sampling rateIPSDisplay module\Motherboard size:76.8*38mm\Auxiliary plate(screen)size:38*19.8mm\Line length:150mm\\power supply:5V DC\Sample rate signal input:LRCK\Support sample rate input:PCM44.1~384KHZ\ DSD64~DSD512\IPSScreen size:1.14Inch full viewIPSscreen\Screen resolution:135*240dots\\It is easy to use，Just power the module5VDC voltage，The sample rate display only needs to input oneLRCKSignal and groundGNDJust two wires。\\Another buyer who doesn't understand will ask，What is?LRCKsignal，LRCKSignal is the audio frame rate signal，It is the frame rate signal of left and right channel data of sound，Different formats of the file output frame rate is not the same，So this module can use this feature to collect frequency and display it intuitively through the display screen，For your convenienceDIY。\\Someone must ask again，There areLRCKsignal？\Good question，I know I'm a novice at a glance，So I'll give a few simple examples here:For example, the Italian interface card，XMOSInterface card，Bluetooth module，And beltIISDigital broadcasting board with output interface，CDMachine and so on，Some of them can writeLRCK This is clear at a glance，But some can writeFSCK，It's also writtenSCKOf，It doesn't matter if you don't understand，FirstGNDConnect，LRCKThis thread can be touched one by one, and the display is normal。

 



 


 



Wiring instructions for circuit board and shock head (ceramic plate transducer) :



 


1. Shock head two wiring, two ceramic pieces of the middle of the wiring piece for the positive pole, by the upper and lower metal column for the negative pole, remember not to connect the reverse;



 


2. The silver-coated side of the ceramic plate of the transducer is a negative electrode, while the larger side of the other two silver layers is a positive electrode, and the smaller side is a negative plate. When welding the power cord, it must be welded on the side with two silver layers, and the other side is a vibrating surface, which can be pasted under the washing basin (this is the component description of the ceramic plate transducer purchased). The silver layer on the ceramic plate is not resistant to high temperature. When welding the power line, the temperature of the soldering iron shall not exceed 280 degrees. It is better to use the constant temperature soldering iron and set the soldering iron temperature as 250 degrees.



 


3. The larger side of the shock head (with a screw hole) is the shock surface that can be glued to the bottom of the cleaning basin. The cleaning basin should be grounded reliably.



 


4. Shock head or transducer ceramic plate application shock head glue firm paste on the bottom of the cleaning basin, can also be used AB adhesive paste, but the effect is slightly poor, such as using epoxy resin ratio of 10:4 can be;
