SparkFun MicroView - USB Programmer Arduino, Other, Sparkfun Originals Power Plant & Driveline Systems Using these power over EthernetThe MicroView is the first chip sized Arduino compatible module that lets you see what your Arduino is thinking using a built in OLED display. This USB programmer connects directly to the MicroView and lets you not only program the module, but use it to interface with your computer, Rapsberry Pi, or other USB device. The programmer has both male and female headers which allow it to be plugged into a MicroView module and a breadboard at the same time,
