Small interface-board for noisy environments
A small interface-board for noisy environments has been developed. It has an RS485 interface where you can control termination and bias resistors. It also has a mode for BPS (Bits-Per-Second) signalling for a very low signalling rate of critical messages in a noisy environment.
The RS485 wires may be used for for supplying power to external devices, and the board can vary the voltage and sense the power used. Thanks to these options the board can also interface a wide range of (analogue) sensors.
