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 Arduino boards and 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 adaptor). The programmer also acts as a USB-to-TTL serial adaptor, 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.
The Pololu USB AVR Programmer v2.1 is a drop-in replacement for the older Pololu USB AVR Programmer v2 with several hardware improvements that are described in the “Comparison to previous AVR programmers” section below.
This product requires a USB A to Micro-B cable to connect to a computer.
The programmer should work with all AVRs that can be programmed with the AVR ISP (in-system programming) interface, which is also known as in-circuit serial programming (ICSP), serial programming, or serial downloading, but it has not been tested with all devices. We expect it to work with most AVRs in the megaAVR (ATmega) family, and it works with some members of the tinyAVR (ATtiny) family, but it does support the Tiny Programming Interface (TPI), and it does work with the XMEGA family or with 32-bit AVRs. The programmer features upgradable firmware, allowing updates for future devices.
The programmer is designed for use with AVR microcontrollers running at either 3.3 V or 5 V. By default, the programmer expects the target to be self-powered, but it can be configured to deliver power to the target device in low-power systems.
We support using the Pololu USB AVR Programmer v2.1 and its configuration software on desktop versions of Windows (7, 8, and 10), Linux, and Mac OS X 10.11 or later. Older versions of Windows are not supported.
This programmer doubles as a USB-to-serial adaptor. The programmer installs as two virtual COM ports: one for communicating with programming software and one for general-purpose serial communications. This means that you can seamlessly switch between programming an AVR and debugging it through the TTL serial port without having to open and close your terminal program. In addition to the serial transmit (TX) and receive (RX) lines, the programmer lets you use A and B as serial handshaking lines that can be configured using our software.
The six pins on the serial header (GND, A, VCC, TX, RX, and B) are arranged to be similar to the pinout of commonly-available FTDI USB-to-serial cables and breakout boards. In the default configuration, pin B is used as the DTR output (and pin A is an unused input), which allows you to plug the programmer directly into a variety of Arduino-compatible boards (including our A-Star 328PB Micro) and use it to upload programs to the board via a serial bootloader.
The Pololu USB AVR Programmer v2.1 ships fully assembled with ISP and serial connectors soldered in, and it includes the accessories shown in the picture below. The 6-pin ISP cable can be used to program AVRs. The 1×6 double-sided male header can be plugged into the serial header to effectively reverse its gender (making it possible to connect that header to a breadboard or female jumper wires).
The Pololu USB AVR Programmer v2.1 (product #1372) is a drop-in replacement for our older Pololu USB AVR Programmer v2 (product #3170) with three hardware improvements:
Compared to the original Pololu USB AVR Programmer (product #1300), the Pololu USB AVR Programmer v2.1 features a number of improvements:
This v2.1 programmer does not include a USB cable, and it does not have the SLO-scope bonus feature. In addition to these changes, many other details are different between the v2.1 programmer and the original; please be sure to refer to the user’s guide for the v2.x programmers to familiarise yourself with this programmer.

User’s manual for the Pololu USB AVR Programmer v2.
This guide explains how to get started programming your Orangutan or 3pi Robot in Windows, Linux or Mac OS X. It covers setting up an AVR development environment (Atmel Studio for Windows users), installing the Pololu AVR C/C++ Library, and setting up the Pololu USB AVR Programmer.
