Build More with Pololu USB AVR Programmer v2.1
The Pololu USB AVR Programmer v2.1 is a practical support part for wiring, level shifting, programming, or mounting in embedded builds.
It helps make integration easier and cleaner in prototypes as well as finished systems.
Why you'll love it
- Simple PC connection: uses a standard USB A to Micro-B cable (not included)
- Wide software support: compatible with Microchip Studio, AVRDUDE, and Arduino IDE via STK500 protocol
- 3.3V/5V friendly: supports both and can auto-switch based on detected target VCC
- Optional target power: can be configured to power the target at 3.3V or 5V in low-power systems
- USB-to-serial built in: TTL-level serial port (installs as two COM ports: one for programming, one for serial)
- Recovery helper: includes a 100 kHz clock output useful for reviving misconfigured AVRs
What you can build
A useful add-on for prototype wiring, level shifting, board mounting, connector work, or programming tasks in embedded systems.
