Works with/without Bootloader for target MCUĪrduino as ISP runs serial communication at 19200 baud rate, that's why it is necessary to change the baud rate of HC-05 Programmer Chip serial link.Can be used to flash Arduino Bootloader in AVRs.Rechargeable LiPo can power programmer and target AVR chip.
