Enable/Change The BT Pair number All of our Bluetooth audio amplifier boards and Bluetooth audio receiver boards use AudioB plus module as the core bluetooth receiver module. The default bluetooth name is “BT SPEAKER”. Maybe you want change it to a special name or add a password to this module. We just updated the AudioB plus design…
USB Boarduino is very much similar to DC boarduino. A USB boarduino board has a USB socket in place of DC barrel, that’s all. This product is no longer sold by Adafruit, so, we cannot get the description. However, if you want to order or redesign it, here are the files: Original product link Assembly…

This is a very interesting project for beginners. We had made similar project several years ago and published on BuildCircuit.COM. Check out this page. In this project, music from an audio source can be transmitted wirelessly via infrared medium. There are two kits included in this package. One is transmitter and the other is a receiver….
We have been using different online Gerber viewers for checking our Gerber files before sending the PCB designs for manufacturing. We have now started using EasyEDA’s Gerber viewer because it helps us to visualize the PCB that would appear after it is manufactured. The application is pretty straightforward and we can check different files to see the changes on…
Few months ago, we had published an article about EasyEDA and described about its features. We see EasyEDA as one stop solution for all the PCB design and manufacturing processes. Check out the previous article about EasyEDA. EasyEDA has been providing most of the services related to PCB/circuit design and manufacturing to its customers. The only thing…
Here is a simple and a low cost Lithium Battery charging breakout board. This article is about the charger breakout board based on TP4056. It uses a Micro USB for connecting the breakout board to any computer or ‘USB wall adapter’. It works with linear charging method. It offers 1000mA charge current by default but…
