The PIC-PG2C is a low-cost serial port programmer that programs PIC microcontrollers without needing an external power supply. It connects to a computer via RS-232 and uses ICPROG software to program supported PIC devices via the ICSP interface. Key features include programming 8, 18, 28 and 40-pin PICs, taking power from the serial port, and supporting various common PIC models for programming and serial EEPROM memory devices.
