The benefit of AVRTSB is automatic reset of MCU with DTR or RTS line. The second line is set to HIGH value (+12V) for power RS232<->TTL convertor directly from serial port. All parameters are given only from command line without user interraction. This makes AVRTSB perfect for integration with IDE for automatic upload new firmware after compilation.

1. Small size - only 512 byte
2. Software emulated serial interface a thus configurable for use with all MCU pins.
3. Secure access by password
