 >the MCU does not have to deal with the FAT file system, it only sends instructions to the chip on the communication bus you like (SPI, UART (HW serial, SW serial)), and the magic happens in the chip.
 >The chip can do more, e.g to handle HID devices(usb keyboard, mouse, joystick ...) but this feature is not yet used in the library, maybe in the future.

 ## Getting Started
-Jan 05, 2020 The chip is able to handle SD card also, test version of the lib and the modification steps are available [here](https://github.com/djuseeq/Ch376msc/tree/SDcard).

  ### PCB modding for SD card
  > If you planning to use the chip for SD card also and you have a pcb like on the photo above, then some soldering skill is required.
  > First of all with a DMM check the pins of the chip(26,25,23 and 7) are theye floating or connected to GND/VCC.
