NuoTo Teensy 2.0++ AT90USB1286 AVR Development Board

SKU CH-GBKG-Z353N

AVR development board with AT90USB1286 microcontroller running at 16 MHz, USB interface, and pre-installed bootloader for direct code loading

  • AT90USB1286 AVR microcontroller with 16 MHz clock for real-time USB projects
  • Single pushbutton programming plus Teensy Loader app for instant code uploads
  • Pre-installed bootloader enables direct USB firmware downloads without external hardware
  • Works on Windows, macOS and Linux with free open-source toolchains
  • Includes USB cable and breadboard-ready pins for solderless prototyping

Compact AVR Development Board

The NuoTo Teensy 2.0++ is a barebone module built around the AT90USB1286 microcontroller running at 16 MHz. It targets hobbyists, students and engineers who need a tiny platform for USB device experiments, keyboard or mouse emulation and general AVR firmware learning. The board arrives with a pre-installed bootloader so code can be uploaded directly over the common USB interface without extra programming hardware.

Breadboard Ready With USB Cable

A row of pins makes the board compatible with solderless breadboards for quick prototyping and temporary circuits. The PC and metal construction keeps the small form factor rigid enough for bench handling while the supplied USB cable provides both power and data connectivity. Free software tools and the Teensy Loader application run on Windows, Linux and macOS, giving a consistent workflow across operating systems.

Upgrades From Basic Breakout Boards

Makers moving up from bare ATmega breakouts gain native USB peripheral support and 128 KB of flash in the same footprint. The single pushbutton programming mode removes the need for an external ISP programmer during development. Projects that do not require USB device classes or the larger flash capacity will not benefit from the step up.

Questions about this item

What USB standard does the Teensy 2.0++ use for programming and communication?

The board connects through a standard USB 2.0 interface, which handles both power and code uploads without an external programmer.

What physical space does the board need for breadboard or enclosure mounting?

Its compact PCB fits a standard solderless breadboard, and the pre-installed header pins leave enough clearance for adjacent components.

How do I load my first sketch onto the AT90USB1286 chip?

Press the onboard pushbutton to enter bootloader mode, then use the Teensy Loader application on Windows, macOS or Linux to send the hex file over USB.
