Pololu USB AVR Programmer v2
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 programmer also features a TTL-level serial port, enabling general-purpose serial communication for debugging or programming microcontrollers with a serial bootloader. An ISP cable and a 1?6 double-sided male header are included with the fully-assembled programmer.
The Pololu USB AVR Programmer v2 is a compact, low-cost in-system programmer (ISP) for Atmel’s AVR microcontrollers. 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 Orangutan robot controllers, and it can also be used to update, replace, or remove the bootloader on Arduino boards and our Arduino-compatible A-Star 32U4 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 Arduino, 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.
Features and specifications
Connects to a computer through USB via a USB A to Micro-B cable (not included)
Emulates an STK500 programmer through virtual COM port interface
Works with standard AVR programming software, including Atmel Studio, AVRDUDE, and the Arduino IDE
Configuration software available for Windows, Mac OS X, and Linux
Supports both 3.3 V and 5 V devices; can automatically switch operating voltage based on detected target VCC
Can optionally power the target at 3.3 V or 5 V in low-power systems
USB-to-TTL serial adapter functionality for general-purpose serial communication
Provides a 100 kHz clock output, which can be useful for reviving misconfigured AVRs
All I/O pins are protected with 470 ? resistors
6-pin ISP cable and a 1?6 double-sided male header included
Supported AVR microcontrollers
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 not support the Tiny Programming Interface (TPI), and it does not 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.
Supported operating systems
We support using the Pololu USB AVR Programmer v2 and its configuration software on desktop versions of Windows (Vista, 7, 8, and 10), Linux, and Mac OS X 10.11 or later. Older versions of Windows are not supported.
Bonus feature: TTL-level serial port
This programmer doubles as a USB-to-serial adapter. 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 and use it to upload programs to the board via a serial bootloader.
The Pololu USB AVR Programmer v2 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).
Comparison to the older Pololu USB AVR Programmer
The Pololu USB AVR Programmer v2 is an updated version of our Pololu USB AVR Programmer (product #1300). It features a number of improvements compared to the original:
Support for devices operating at 3.3 V (in addition to 5 V)
VCC pin can be configured to provide 3.3 V or 5 V power to target in low-power systems
Protection resistors on all I/O lines
More accurate emulation of the ISP frequencies provided by the STK500; you can use the user interfaces of Atmel Studio and AVRDUDE to set your ISP frequency more easily
Usability enhancements for serial interface, such as a more standard pin arrangement (similar to FTDI) and a pre-populated female header
This programmer does not include a USB cable, and it does not have the SLO-scope bonus feature.
