Features

Standard 87C52 CPU clocked at 22.1184 MHz

50 I/O lines!! All I/O lines are clearly labeled and available at the edge of the prototype construction area

32k SRAM, program variables and code (24k usable for code download)

30k Flash ROM, non-volatile program storage and data logging

High speed baud rates: 115200, 75600, 38400, etc. All standard baud rates are supported (except 300 baud)

Display port, works with standard character-based LCD A 16×2 display will be available from PJRC (see photo below)

Eight LEDs, controlled by 8 dedicated I/O lines (not shared with the 50 I/O lines)

Bus expansion with 4 chip select signals, for adding UARTs, A/D converters and other bus-based peripheral chips.

Unregulated, polarity-protected DC voltage input with 2 position terminal block.

PAULMON2 monitor for easy code development without additional equipment.
