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.

The people at Seeedstudio are developing a new portable Digital Osciloscope: New DSO. Preliminary specification:
- 2 Analog channel
- 20mV to 10V/div
- 30Mhz bandwidth
- Analog signal generator output 10hz~20kHz
- Digital signal generator output 10hz~8MHz square wave
- Target price >$150
