The product is compatible withArduino The manufacturer has prepared a user's guidefor Arduino and a library with sample code. |
Most microcontrollers use TTL levels, while a computer serial port typically uses 232 levels. If we want the computer to communicate with MCU, we will need a Grove - 232. Communication between Arduino and the computer will be very convenient thanks to the integrated Groveinterface.
Module Grove is base on MAX3232 and communicates with many data transfer rate, and theoretically supports the connection of up to 230400bps.
