This board is an embedded board for In Sytem Programming (ISP) on MicroController Unit (MCU). There is a basic digital I/O embedded on this board such as LED-logic monitor. Dip switch on this board helps a user debug programs easily. The programs can be downloaded directly to MCU. This board also supports MCU number AT89S51/AT89S52/AT89S53/AT89S8252/AT89S8253 from ATMEL and P89V51RD2 from PHILIPS.
Key Features:
- Support Microcontrollers MCS-51 series as following:
- AT89S51, 4 KB Flash Memory
