Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

LILYGO T-Connect Pro is a DIN rail-mountable, ESP32-S3-based industrial IoT controller with Ethernet, WiFi 4, Bluetooth 5.0 LE, and LoRa connectivity, as well as CAN Bus, RS232, and RS485 interfaces.

Electronica: Arduino makes single-pair Ethernet accessible, and RS485 too Arduino announced a single-pair Ethernet adapter board for its Uno R4 single-board microcontroller at Electronica this morning ...

“By incorporating RS485 connectivity, the Arduino Uno SPE Shield becomes a tool for upgrading RS485 legacy systems or integrating modern technologies with current infrastructures, creating a bridge ...

In this protocol, there are 3 different modes are available. Modbus RTU (Remote Terminal Unit): This is a binary format used over serial connections like RS232 or, more commonly, RS485 Modbus ASCII: A ...

Baudrate and other settings can be configured the same way as the standard Arduino Serial library. For a list of all configuration options click here. PORT1_RS485_BEGIN () PORT1_RS232_BEGIN () ...

The company says the ESP32-C3 board is programmable with the ESP-IDF framework or the Arduino IDE, and provides Arduino code samples for WiFi, RS232 (simple and Modbus), and RS485 (simple and Modbus) ...

The 4 jumper caps (5V/RX/TX/GND) simply link the USB interface to the RS-485 interface. If the jumper caps are removed, the FT232RL circuitry may be used as a standalone USB-TTL interface, and/or the ...

The main advantage of RS-485 over RS-232 is the multiple slave with single Master while RS-232 supports only single slave. Can have a maximum of 32 devices connected to RS-485 protocol. Another ...
