Attention! Before connecting, readthe installation guide. |
Programming
Creating and downloading software, is allowed by thefree environment of the Arduino IDE.Implemented bootloader allows you to send the program directly viathe microUSB cable. A detailed description can be found inthe instructionssupplied by Pololu.
Pulse stabilizer
The board was equipped with pulse 5 V voltage regulator with high efficiency: 80 to 90%.
The efficiency of the system depending on the consumed current for different values of input voltage.
