The ISP adapter allows a standard AVR MCU programmer to program the OpenServo 2.0 using the SPI bus on the ATmega8 and ATmega168 MCUs. Normally the servo will be programmed over the TWI/I2C bus using the bootloader. However a hardware programmer is required to bootstrap the MCU on a new OpenServo or recover an OpenServo with corrupted Flash memory.
