Autonomo¶
Overview¶
We built a next generation, Arduino-compatible board that can record data and trigger actions in any environment. We believe you can save yourself a lot of time by being notified of important information. The information you want and need should come to you, magically. Having to go to your favorite surf spot to see how strong the wind is, or physically measuring how much water there still is in the well nearby your village, is a thing of the past.
The Autonomo is a matchbox-sized powerhouse which uses the new Atmel Cortex M0+ 32bit microcontroller. We designed it to be autonomous (self-sufficient) by enabling it to be powered by a smartphone-sized solar panel. It will allow you to create devices that will notify you of anything. The new M0+ processor packs computing power which is comparable to the first Mac. It will make you wonder why you ever used anything else! Our goal was to create a device which would be able to run indefinitely using solar generated power. Leveraging our years of experience in creating low-powered devices, the Autonomo has been designed to run efficiently and with extremely low power consumption.
Intended use The ExpLoRer is a development/evaluation tool intended for the evaluation of Microchip wireless modules in a Research and Development laboratory environment. It is not a Finished Appliance. Manufacturers who integrate ExpLoRer in a Finished Appliance product must take responsibility to follow regulatory guidelines, for example for CE marking.
