CANChecked CFE18 – CANBUS I/O Expander

CFE18 stands for “Can Bus Function Extension” or colloquially “Can Switch Board” – why is this module needed?

CAN Bus connections in the vehicle sometimes present our customers with major challenges. Especially in motorsport applications when electronics have to be accommodated in the steering wheel and information from adjustment buttons (trimpots) or push buttons has to be transmitted via CAN Bus. The input data is queried and transmitted every 50ms (100Hz – variable from 1Hz to approx. 300Hz – depending on the smoothing ).

CANchecked now offers a small additional module that has 17 inputs: 8 for switches (low side) and 9 for analog inputs (0-5V signal). A voltage converter to ensure connection to a 12V vehicle electrical system is also already integrated.

In the v2 (board v0.8) 3 switching outputs have also been added (low side max 0.5A)

Tested with:
– MoTeC
– MaxxECU
– Ecumaster (EMUB and PMU)
– LinkECU
– Haltech (emulates an IO Expander A + B or just B)
– Emtron
