Pololu USB AVR Programmer v2.1

Product Code:
£7.68 £6.40

This in-system programmer can be used to program AVR microcontrollers and AVR-based controller boards, such as our Orangutan robot controllers and the 3pi robot.

The programmer emulates an STK500 on a virtual serial port, making it compatible with standard AVR programming software, and it supports devices running at either 3.3 V or 5 V.

The Pololu USB AVR Programmer v2.1 is a compact, low-cost in-system programmer (ISP) for AVR microcontrollers from Atmel (now a part of Microchip).

The programmer provides an interface for transferring a compiled AVR program from your computer to the target AVR’s non-volatile memory, allowing it to run the program.

It is a good solution for programming AVR-based controllers like our A-Star 328PB Micro and Orangutan robot controllers. It can also be used to update, replace, or remove the bootloader on some Arduino boards including the Uno, Leonardo, and Mega, and also on our Arduino-compatible A-Star controllers.

This programmer is designed to work well with both 3.3 V and 5 V devices, and it can even be configured to provide power to the target device in low-power systems.

The programmer connects to your computer’s USB port via a standard USB A to Micro-B cable (not included) and communicates with your programming software, such as Atmel Studio, AVRDUDE, or the Arduino IDE, through a virtual COM port using the STK500 protocol.

The programmer connects to your target device via an included 6-pin ISP programming cable (the older, 10-pin ISP connections are not directly supported, but it’s easy to create or purchase a 6-pin-to-10-pin ISP adapter).

The programmer also acts as a USB-to-TTL serial adapter, providing a TTL-level serial port that can be used to communicate with other serial devices from your computer. It ships fully assembled with connectors soldered in as shown.
