I am using MAX3362 RS485 serial data transfer IC with ESP32. Marked pins 1, 2 and 3 are connected to GPIOs of ESP32. Do I need to add any additional pull-up resistors or some termination resistors or will this schematic work?
The RO output is disabled when the /RE is high, so it should have a pull-up resistor. (The internal pull-up of the microcontroller should be enough.)
The receiver does not have failsafe inputs, so the A/B bus lines should have failsafe pull-up/-down resistors (not necessarily on this board, but somewhere on the bus).
A RS-485 bus should have termination resistors only at the two ends, so this board can be connected only to the end of the bus.
All devices on the bus should share their ground, but the connector has only two signals.
