Cooperation with Arduino

The device can be programmed through the Arduino environment, however, due to the small size of the board there are some differences:

  • Pins 2 and 7 are not available due to their use for USB communication.
  • The board operates at 3.3V and 12 MHz, so not all sample programs will work properly.
  • The built-in 3.3 V controller has a current capacity of up to 150 mA.
  • There is no FTDI circuit on the board, an external cable or converter must be used to connect the serial interface. The USB connector is only for program upload.
  • Bootloader takes up 4 kB of flash memory, so the user has 28.672 b at his disposal.
