Standard size breadboard that is perfect for prototypes. It does even have power rails on the sides to allow for more than one power level. The one you will get is white and not transparent as in the picture.Breadboard
A simple mechanical structure, very convenient platform to build upon with 4 DC motors that can be controlled separately. Two levels of acrylic plates to allow for bigger electronics. Very simple assembly.
The module is used for charging of single lithium battery or multiple lithium batteries in parallel, and the charging port can take power from the USB port. output USB micro usb input / usb output / and charging lipo
In our application, especially in some outdoor applications, we often need to use the lithium battery, lithium battery charging problem is a need to solve the problem, we designed this mini lithium battery charging board.
Board size is very small , It can u solar
