This device is a programmer for AVR-based controllers, such as our Orangutan robot controllers and the 3pi robot. The programmer emulates an AVRISP v2 on a virtual serial port, making it compatible with standard AVR programming software. Two additional features help with building and debugging projects: a TTL-level serial port for general-purpose communication and a SLO-scope for monitoring signals and voltage levels.
General AVR ISP Programmer
The Pololu USB AVR Programmer is an extremely compact, low-cost in-system programmer (ISP) for Atmel's AVR mirocontrollers, which makes this device an attractive programming solution for AVR-based controllers like Pololu Orangutan robot controllers. The USB AVR programmer connects to your computer's USB port via an included USB A to mini-B cable and communicates with your programming software, such as AVR Studio or AVRDUDE, through a virtual COM port using the AVRISPV2/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 should work with all AVRs that can be programmed by an AVR ISP, but it has not been tested on all devices (it has been tested with all Orangutan robot controllers and the 3pi Robot). The programmer features upgradable firmware, allowing updates for future devices. It does not currently work with Atmel's XMega line of microcontrollers.
The programmer is powered by the 5V USB power bus, and it is intended for programming AVRs that are running at close to 5 V (note that the programmer does not deliver power to the target device). You can use it to program AVRs running at lower voltages if you use voltage dividers to decrease the voltage of the programmer's output pins to a level that is safe for your microcontroller.
The Pololu USB AVR Programmer ships with a 12" (30 cm) 6-pin ISP programming cable and a 6' (1.8 m) USB A to mini-B cable. It does not ship with software or documentation, but software (including drivers) and documentation can be found under the resources tab.
