Pololu USB AVR Programmer v21

This in-system programmer can be used to program AVR microcontrollers and AVR-based controller boards, such as our A-Star 328PB Micro, 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 3.3V or 5V. 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 16 double-sided male header are included with this fully-assembled programmer. 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 AVRs non-volatile memory, allowing it to run the program. It is a good solution for programming AVR-based controllers like ourA-Star 328PB MicroandOrangutan robot controllers. It can also be used to update, replace, or remove the bootloader on someArduino boardsincluding the Uno, Leonardo, and Mega, and also on our Arduino-compatibleA-Star controllers. This programmer is designed to work well with both 3.3V and 5V devices, and it can even be configured to provide power to the target device in low-power systems. The programmer connects to your computers USB port via a standardUSB A to Micro-B cable(not included) and communicates with your programming software, such as Microchip Studio, AVRDUDE, or the Arduino IDE, through a virtual COM port using the STK500 protocol. The programmer connects to your target device via an included6-pin ISP programming cable(the older, 10-pin ISP connections are not directly supported, but its 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. The Pololu USB AVR Programmer v2.1 is a drop-in replacement for the olderPololu USB AVR Programmer v2with several hardware improvements that are described in the Comparison to previous AVR programmers section below. This product requires aUSB A to Micro-B cableto connect to a computer. Features Connects to a computer through USB via aUSB A to Micro-B cable(not included) Emulates an STK500 programmer through virtual COM port interface Works with standard AVR programming software, including Microchip Studio, AVRDUDE, and the Arduino IDE Configuration software available for Windows, Mac OS X, and Linux Supports both 3.3V and 5V devices; can automatically switch operating voltage based on detected target VCC Can optionally power the target at 3.3V or 5V in low-power systems USB-to-TTL serial adapter functionality for general-purpose serial communication Provides a 100kHz clock output, which can be useful for reviving misconfigured AVRs All I/O pins are protected with 470 resistors 6-pin ISP cableand a 16double-sided male headerincluded Comprehensiveusers guide 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 doesnotsupport the Tiny Programming Interface (TPI), and it doesnotwork 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 3.3V or 5V. 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 v2.1 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. Bonus feature: TTL-level serial port This programmer doubles as a USB-to-serial adapter. The programmer installs astwovirtual 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 useAandBas 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 ourA-Star 328PB Micro) and use it to upload programs to the board via a serial bootloader. Included accessories 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. The6-pin ISP cablecan be used to program AVRs. The 16double-sided male headercan be plugged into the serial header to effectively reverse its gender (making it possible to connect that header to abreadboardor femalejumper wires).
