ArduinoRS485

Communication

Enables sending and receiving data using the RS-485 standard with RS-485 shields, like the MKR 485 Shield.
This library supports the Maxim Integrated MAX3157 and equivalent chipsets.

Compatibility

This library is compatible with the samd, mbed_portenta, mbed_opta, mbed_nano, renesas_uno architectures so you should be able to use it on the following Arduino boards:

• Arduino MKR FOX 1200
• Arduino MKR GSM 1400
• Arduino MKR NB 1500
• Arduino MKR VIDOR 4000
• Arduino MKR WAN 1300 (LoRa connectivity)
• Arduino MKR WAN 1310
• Arduino MKR WiFi 1010
• Arduino MKR ZERO (I2S bus & SD for sound, music & digital audio data)
• Arduino MKR1000 WIFI
• Arduino Nano 33 BLE
• Arduino Nano 33 IoT
• Arduino Zero
• Portenta H7
• Arduino UNO R4 Minima
• Arduino UNO R4 WiFi
• Arduino Nano RP2040 Connect

Compatibility Note

Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.
