The CRMXchip is the world’s smallest wireless lighting control solution. Built on the latest chip technologies, CRMXchip includes everything needed for manufacturers to add a multi functional wireless DMX receiver into high volume products.

Building on years of experience in manufacturing industry leading wireless integration modules, LumenRadio’s CRMXchip is an industry first – a compact, developer friendly chip which can be integrated into products with ease. Interfaces are provided for SPI, TTL and (via external drivers) RS485 signals, including an industry first “DMX Window” functionality, which removes the need to process a full 512 slot to locate start addresses within a product. This innovation enables extremely low cost wireless-only products to be manufactured with almost no DMX processing requirements.
