Hi,
I'm called to design a multi drop network where the nodes communicate using 2 wires. The distance from 2 nodes is maximum 20 meters. The wires will run along the mains (220 V).
I requested a quotation for the following part:
MAX3483ECSA (3 Volt, ESD protetected, transceiver)
and they told me that 4000 parts cost 1.90 Euros each... amazing!
Are there any cheaper pin-to-pin part replacement?
Does, using CAN transceivers instead of RS485 ones, make any sense?
thanks for any help, Enrico
