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 3.3 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 this fully-assembled programmer.

Features and specifications
