Interface Modules for Arduino, ESP32 & Microcontroller Projects

Communication and interface modules allow microcontrollers to connect to other boards, sensors, displays, storage devices, computers and control systems. AuscomTech stocks modules commonly used with Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, STM32, STM8 and ATtiny / AVR projects.

These modules are commonly used for serial communication, data logging, signal conversion, I/O expansion, bus communication, wireless projects, sensor networks and troubleshooting. Always check the voltage, pinout, communication protocol, driver requirements, library support and wiring before connecting a module to your project.

USB Serial, RS485, CAN, Logic Level & Signal Converter Modules

Many electronics projects need to translate between different communication types or electrical signal levels. USB to serial modules are useful for programming and debugging, RS485 modules are commonly used for longer wired communication, CAN modules are used for bus-based projects, and logic level converters help connect 3.3V and 5V devices safely.

For raw PCB-style signal conversion modules used with microcontrollers, use this category. For finished industrial signal isolators, 4-20mA converters, 0-10V converters, DIN rail converters or process signal products, browse our industrial signal isolators and converters category.

Frequently Asked Questions

Do you sell communication modules for Arduino and ESP32?

Yes. AuscomTech stocks communication and interface modules suitable for Arduino compatible boards, ESP32, ESP8266, Raspberry Pi compatible boards, STM32 and other electronics projects.

What is a USB to serial module used for?

A USB to serial module is commonly used for programming, debugging and communicating with microcontrollers or serial devices using TTL UART signals.

What is the difference between RS485, RS232 and CAN modules?

RS485, RS232 and CAN are different wired communication standards. RS485 is commonly used for longer-distance serial communication, RS232 is an older serial interface standard, and CAN is a bus system often used in automotive, machinery and embedded control applications.

When do I need a logic level converter?

A logic level converter is useful when connecting devices that use different signal voltages, such as a 3.3V microcontroller connected to a 5V module.

Can you help me choose the right interface module?

Yes. If you are unsure which module suits your project, contact AuscomTech with your controller board, the device you need to connect, voltage levels, communication protocol and any wiring details.
