Arduino Compatible for GBRL

Having had lost of experience with Arduino, I selected the “BUONO UNO” Arduino compatible board.

GREAT DEAL

For US$10, it is a heck of a deal.

INNOVATION and IMPROVEMENTS

Features implemented in the BUONO:

  • Selectable voltage operation: 3.3V or 5V
  • Better location for LEDs and reset switch, especially if you use a shield
  • Higher power. Maximum of 1.8A for peripheral devices
  • Cleaner AVCC. LC Low pass filter for the AVCC allows the ADC to be more accurate
  • Easy access ground terminal to facilitate measurement and trouble shooting

Power is provided by the FP6182 DC-DC converter [link]. It can provide up to 2A of current

Silicon Labs C8051F321 USB bridge chip [link]. (Make sure you have the latest firmware [link]) for full compatibility with Arduino UNO R3,

I am not sure why use a Silicon Labs parts, except it may be less costly and does not require an external oscillator.
