Function USB to TTL serial adapter for programming microcontrollers over serial bootloaders. Key benefits Enables firmware flashing for a range of boards that use serial programming Supports boards such as Boarduino, Bareduino, ESP8266, Mini minimOSD, Xmega Xplained, mini pro, and other serial programmable devices After driver installation, provides a serial port on your computer for flashing and communication Simple, reliable way to connect your computer to target boards for development and testing Compatibility highlights Works with devices that can be programmed over serial using standard bootloaders and serial interfaces Suitable for common microcontroller development and debugging workflows Setup and use Install the driver to enable a serial port on your computer Connect the adapter to your target board using the appropriate TTL level signals Use your preferred development tools to flash firmware or access serial output Performance and reliability Designed for stable serial communication and firmware flashing between PC and target boards Provides a straightforward bridge between USB and TTL serial protocols Use scenarios 1) Flash firmware to Arduino style boards such as Boarduino, Bareduino, or Mini Pro / Pro Mini via serial bootloader 2) Program ESP8266 modules for firmware updates and initial configuration 3) Develop and debug on Xmega Xplained and other boards that support serial programming and console access Practical considerations Driver installation is required; once completed, the adapter exposes a serial port on the computer for ongoing use What you get (conceptual) A USB to TTL serial adapter designed for programming and serial communication with microcontroller boards that accept serial bootloaders
