The Hologram Dash is a cellular development kit for rapid application development. It can be used for prototyping, as cellular gateways, or as modules embedded within a final product. Because the hardware and firmware are open source, the Hologram Dash can scale with your production, even to the point of embedding the reference design within your own designs.
