Pololu 3170 USB AVR Programmer v2
The Pololu 3170 USB AVR Programmer v2 is a compact, high-performance in-system programmer designed for AVR microcontrollers using the STK500 protocol over USB connectivity. Embedded systems engineers, firmware developers, and hobbyists rely on this programmer for reliable code flashing and debugging of Atmel AVR-based projects without requiring external power supplies. This device solves the critical challenge of rapid prototyping and production programming by offering plug-and-play USB connectivity with cross-platform software compatibility on Windows, macOS, and Linux environments.
Product Overview
The Pololu 3170 USB AVR Programmer v2 operates as a USB-to-serial bridge that implements the STK500 programming protocol, enabling seamless communication between your development computer and AVR microcontroller target boards. The programmer features a standard 6-pin ISP (In-System Programming) connector that connects directly to the target device's programming header. Unlike traditional parallel port programmers, this USB-based solution provides true plug-and-play functionality with automatic driver installation on most systems, eliminating compatibility issues associated with legacy parallel port interfaces. The device draws power directly from the USB port, making it ideal for field programming and portable development setups.
What distinguishes the v2 revision is its improved firmware stability, enhanced compatibility with modern AVR microcontroller variants including the ATmega328P, ATtiny85, and ATmega2560 series, and optimized signal integrity for reliable programming at standard clock speeds. The programmer supports both slow and fast programming modes, allowing developers to optimize for either programming speed or compatibility with target boards featuring marginal power supplies or lengthy ISP cable runs. The compact form factor and integrated USB cable make this an essential tool for electronics labs, educational institutions, and professional embedded systems development environments.

How to Use
Begin by connecting the Pololu 3170 USB AVR Programmer v2 to your development computer via the integrated USB cable. On Windows systems, the device typically installs automatically or may require the libusb driver installation. On macOS and Linux, ensure AVRdude is installed through your package manager. Locate the 6-pin ISP header on your target AVR board and connect the programmer's ISP cable, ensuring proper pin alignment with Pin 1 marked on both the programmer and target board. The standard pinout includes MISO, VCC, SCK, MOSI, RESET, and GND connections.
In your development environment, configure the programmer settings to use STK500 protocol with the appropriate serial port or USB device identifier. If using AVRdude from the command line, specify the programmer type as stk500v2 and select the correct AVR device model matching your target microcontroller. For slow programming mode on boards with marginal power supplies, reduce the clock frequency setting in your programming software. After programming completes successfully, disconnect the ISP cable and verify program execution on your target board. For production environments, document your programmer settings and create batch scripts to automate the programming process across multiple units.
Frequently Asked Questions
What is the difference between Pololu 3170 v1 and v2?
The v2 revision includes improved firmware stability, better signal integrity for modern AVR microcontroller variants, and enhanced compatibility with contemporary development tools. The v2 offers more reliable programming performance, especially with longer ISP cable runs and target boards featuring marginal power supplies. If you are working with newer ATmega or ATtiny variants, the v2 is the recommended choice.
Can this programmer work with Arduino boards?
Yes, the Pololu 3170 is fully compatible with Arduino boards and Arduino-compatible AVR platforms. You can use it to program Arduino bootloaders or upload sketches directly via ISP, bypassing the serial bootloader. This is particularly useful for boards without USB connectivity or when you need to reprogram the bootloader itself. Simply connect the 6-pin ISP header to your Arduino board's ISP pins and configure AVRdude or the Arduino IDE to use this programmer.
Does this programmer require external power supply?
No, the Pololu 3170 is completely USB bus-powered and draws all operating current from the USB port. This eliminates the need for external power supplies, making it ideal for portable development, field programming, and educational settings. The programmer can supply limited power to target boards during programming, though boards with high power consumption should have their own power supply connected.
Which software tools are compatible with this programmer?
The Pololu 3170 implements the standard STK500 protocol, making it compatible with AVRdude, Atmel Studio, CodeVisionAVR, BASCOM-AVR, and most other AVR development tools. On Windows, it works with the Arduino IDE for ISP programming. On Linux and macOS, AVRdude is the primary tool. The open-source nature of the STK500 protocol ensures broad software compatibility across platforms.
What microcontroller families does this programmer support?
The Pololu 3170 supports all Atmel AVR microcontroller families including ATmega series (ATmega328P, ATmega2560, ATmega168, etc.), ATtiny series (ATtiny85, ATtiny84, ATtiny2313, etc.), and AT90 series devices. It is compatible with virtually any AVR microcontroller that implements the STK500 ISP protocol. Verify your specific microcontroller is listed in your programming software's device database before attempting to program.
