Snowflake : E-paper smart tags

A product prototype for Electronic Shelf Labelling Systems (ESL) designed and developed for a client in 2012. Ultra low power performance was achieved through the use of efficient power system design and low-power micro-controllers. Custom graphics drivers were developed to enable low power graphics processing on board the devices. A novel driving mechanism to increase the refresh rate of the usually slow e-paper displays was also implemented.The product was licensed and sold to the client (undisclosed).
