A Couple of Interesting H/W Developments

The official Arduino team is introducing new boards. You can read the story here: New Arduino. The small board is called ARDUINO UNO. The larger board is the Arduino UNO MEGA. Click the image for a GIANT resolution image (my own Arduino UNO taken with a micro lens)

  • Same form factor, backward compatible with everything and same $30 price
  • New USB interface chip with
    • Has the Arduino team’s own USB vendor ID (this means the OS will recognize the device as “Arduino”).
    • Minor roadblock to clone vendors according to this analysis
  • 3.3V supply is generated by a LDO low noise regulator, increased from 50 mA to 150 mA according to regulator data sheet
  • Available everywhere (I like NKC Electronics). Sometimes you can get it through Amazon with free shipping

Although the update is not really major, it gives the official Arduino board a small advantage over a clone board. As indicated above, the Arduino team has obtained a USB vendor ID and a lot of work has been invested in the branding and aesthetics of the board.

Analysis of the new board here. Another good one here.
