Gravity: Bluno Beetle Shield

SKU: DFR0356

The Bluno Beetle Shieldexpands the Beetle's single pin I/Os analog and digital I/O pins to the 3 pin "gravity" interface, giving more power and ground connections and making it easier to attach "gravity" interface modules. It also includes a convenient external power supply and 5-8v switch to power the board on and off. To use the shield, the Bluno Beetle is stacked on to the shield's I/O pins and soldered in place.
