Extremely powerful ISP-Programmer for all ATMEL-AVR-Controllers programmable via SPI-Interface. Remarkable is the own fast 32-bit ARM-Cortex-M0 onboard processor with specially developed firmware, which allows very fast programming cycles. NEW! The adaptive bit rate adjustment automatically detects a SPI bit rate that is set too high and adjusts it independently. Via two DIL switches even a target voltage supply is possible. This can be set to 5V or 3.3V and can be switched on and off. Laser-cut plexiglass housing. Two built-in status LEDs indicate the current state of the programmer.
