Alongside our standard range of products, Cambridge Microprocessor Systems Ltd is pleased to provide customers with a bespoke design and manufacturing service. We can tailor existing designs to meet customer requirements or can start from scratch to provide a complete package. Our design and manufacturing processes under the one roof can save time and production costs.

We supply a good selection of peripheral boards, designed to be used with our FlashModule range, as well as cards compatible with our CCLIX boards.  The PROton PR-60 Memory & I/O is a 1 M-byte non-volatile memory SD card, ideal for use with the PROton PR-60.    The 8 channel PROton solid state relay is used with PROton PR-60, PR-40 and PR-25.  Also in the PROton range is an 8 channel opto-isolated input, also designed for use with the PROton PR-60, PR-40 and PR-25.   Additionally, we have available the K-090, an I2C interface board with 8 channels of opto-isolated inputs.  The K-091 4 channel relay outlet can be used with any controller with an I2C interface.  Another product in the range is the K-092 I2C interface board, which has 4 channels of calibrated analogue input.  Please visit our website for more information on peripherals.

Data Loggers

We have a range of dedicated products for logging events and environmental conditions, including the iMind and iTell ranges, from as low as £95.

iMind Temperature Loggers are low-cost, stand-alone loggers that allow monitoring and storing of temperature changes between -40 and 85 degrees C. This can assure that goods are being stored at the right temperature and that temperature controlled equipment is working properly, in applications such as chillers, fridges, cold stores, transport, chemical stores and medical fridges or freezers.

The iTell Connected Data Loggers use Ethernet or mobile communications to collect data from multiple sources and log it on a web server. The web server can then be logged into and the data can be reviewed.


Cambridge Microprocessor Systems are an authorised UK distributor of DrayTek's state-of-the-art networking solutions, providing world-leading products from £35.
