The M-508/M-508T is a mini-mighty Linux-ready ARM9-based single board computer. Users can operate the M-508/M-508T the same way as they do on a normal Linux desktop. The M-508/M-508T comes equipped with one Ethernet, four RS-232/485 ports, two USB 2.0 host ports, plus one SD memory card slot and 32x GPIOs in an incredible small package measuring only 105x 75mm.

Operates in -20 to 80C Environment (M-508T)
The M-508T is especially designed to withstand environmental extremes. All the major components used by the M-508 are of industrial grade, to ensure continuous operation in -20 to 80C temperature range.

512KB Non-volatile SRAM (M-508T)
For critical applications, working data needs to be safely kept while system power goes down incidentally. The M-508T provides 512KB non-volatile SRAM for fast and safe data retention, eliminating the need of an trouble-making external battery.

Four 921.6Kbps RS-232/485 TTY Ports
The M-508 provides four 921.6Kbps RS-232/485 TTY ports. Port 1, 2, 3 support standard RS-232/485. Port 4 supports RS-232/422/485. Port 2 also features full RS-232 supporting for modem connection.

Thirty-two CMOS-level GPIOs
The M-508 comes with 32x CMOS-level digital I/Os. Each I/O pin can be individually programmed as input or output.
