  R105 Gazelle Microcontroller

Low cost embedded controller 16 Inputs + 14 Outputs + Analog I/O + Ethernet


We are sorry that at this moment we can not guarantee further supply of this R105 controller. The R105 Super Gazelle™ Microcontroller is a compact, ultra high performance, low-cost embedded controller built around the new Cygnal™ 8051 50 MIPS system-on-chip processor. This C-programmable high-speed controller has digital, analog, and communications capabilities in a small footprint. The R105 Super Gazelle's compact design enables ease of use and versatile integration into any in-house or OEM application.

Available interfaces include digital, analog, Ethernet, serial, and high-current drivers. The standard Super Gazelle is packaged in a rugged metal enclosure with a large format 4x20 LCD and a 2x6 tactile keypad. The Super Gazelle also has an expansion port for additional I/O. Modbus support is available.
