So far tested just on bench. RE & DE can be connected and be driven by only one signal line, because RE (enable receiver) is active low and DE (enable transmitter) is active high. Note: in such configuration protocol have to be able to ignore possible noise on the bus. All signals are connected to pins and bus is also connected to screw terminals on top side of module. Note: polarity of bus lines is important and needs to be same on all transceiver on bus. Due to IC datasheet (it's MAX485) there can be 32 transceiver on one bus.

They look good. I didn't test them yet but I assume they will work fine.

This should be in a "bus" kit for Arduinos as it is a good education tool for learning all the micro busses, like RS232, RS485, I2C, SPI, CANBUS, etc.

Dotarł na czas pomimo ograniczeń w podróży z powodu Covid-19. Był odpowiednio zapakowany i w dobrym stanie. Ale jeszcze jej nie przetestowałem.

Arrived on time despite the travel restrictions due to Covid-19. It was properly packaged and in good condition. But I haven't tested it yet.
