Our team is testing the TinyDuino, which is a new, small, stackable microcontroller with low power consumption. It can be used to collect data or control systems as a tiny computer, and could be ideal for small satellites. We are testing it through logging data from a magnetometer, temperature sensor, and accelerometer to a micro SD card. This microcontroller could reduce the cost of launching small satellites by allowing them to be smaller. It could also allow standard sized craft to do more.
