Design Notes
Place 0.1 Β΅F bypass capacitors close to the VCC and VIO pins to filter high-frequency noise. Use a 10 Β΅F bulk capacitor on VCC if the supply is shared with other components. Ensure the ground plane is continuous under the device to minimize EMI.
Keep the RS-485 bus traces (A, B, Y, Z) as short as possible and route them as a differential pair with controlled impedance (typically 120 Ξ©). Avoid stubs and use termination resistors at both ends of the bus to prevent reflections. Place the termination resistor close to the connector.
Do not forget to connect the VIO pin to the logic supply voltage. If VIO is left floating, the device may not operate correctly. Also, ensure the DE and RE pins are properly controlled to avoid bus contention. Use pull-up or pull-down resistors as needed.
