Two years ago Microchip introduced serial EEPROMs with UNI/O. The speciality is the single pin data interface, so the memory chip needs only 3 pins including power. This can be great help for the smallest 6-pin microcontrollers like PIC10F or ATtiny10 series which doesn’t have any non-volatile memory writable from application itself. Memory densities range […]

Seeed’s DSO Quad available for preorders
After the successful DSO Nano Seeed is finishing development of new pocket scope called DSO Quad. Engineering samples started shipping in late December 2010, now the beta testing run is available for preorders at $159. Be aware that the actual shipping is scheduled for March. DSO Quad has two analog inputs up to 36 Msps, […]
Arduino shield database
Shieldlist.org is searchable database containing information about more than 200 Arduino shields. Every shield has its own page with short description, link to its homepage, licensing and source information as well as very useful diagram of used pins. more features are planned in the future. If you submit new shield you can get a Freetronics […]
Minimalistic LED dice
This dice by Rickard Gunee is interesting because it uses one of the smallest microcontrollers, a 6-pin PIC10F200. With 4 GPIO it’s just one pin more than the voltage regulator. Using multiplexing it controls 4 strings of LEDs and even one input button. The whole project is open source and also available as kit.
