USB UART Adapters for Arduino, ESP32 & ESP8266 Projects

USB to serial modules are commonly used when a board or device does not include onboard USB programming. They are useful for uploading code, flashing firmware, reading serial monitor output, debugging boot messages, configuring modules and communicating with UART devices.

These modules are often used with ESP-01, ESP-07, ESP-12E, ESP-12F, ATtiny, STM32, Arduino compatible boards, serial sensors, GPS modules, Bluetooth modules and other electronics hardware. Always check the logic level, voltage, pinout, driver chip, USB connector type and operating system driver requirements before ordering.

CH340, FTDI, CP2102 & USB TTL Serial Adapters

Different USB to serial modules use different interface chips and may require different drivers. CH340 and CH341 modules are common low-cost adapters, CP2102 modules are widely used in development boards, and FTDI-style adapters are popular for programming and serial communication projects.

Frequently Asked Questions

What is a USB to serial module used for?

A USB to serial module is used to connect a computer USB port to a TTL-level serial UART device. It is commonly used for programming, debugging, firmware flashing and serial communication.

Can I use a USB to serial adapter to program ESP modules?

Yes, many bare ESP modules such as ESP-01, ESP-07 and ESP-12 can be programmed using a suitable USB to TTL serial adapter, correct wiring and the correct boot mode setup.

What voltage USB to serial module do I need?

It depends on the device you are connecting. Many ESP32 and ESP8266 modules use 3.3V logic, while some other boards may use 5V logic. Always check the target device before connecting.

Do USB to serial modules need drivers?

Some modules may require drivers depending on the chip used, such as CH340, CH341, CP2102 or FTDI-style adapters, and depending on your operating system.

Can you help me choose the right USB to serial module?

Yes. If you are unsure which adapter suits your project, contact AuscomTech with your target board or module, required logic level, USB connector type and what you are trying to program or communicate with.
