 Only
limited stock of this R101is still available. We are sorry that at this moment
we can not guarantee further supply of the R101 controller. The R101 Gazelle Microcontroller is a rugged, compact,
high performance, low-cost embedded controller built around the Cygnal™ 8051
system-on-chip
processor. This C-programmable high-speed controller has digital, analog,
and serial capabilities in a small footprint. The R101
Gazelle's compact design enables ease of use and versatile
integration into any in-house or OEM application.
Available interfaces
include digital, analog, serial, and high current drivers. The standard
Gazelle is packaged in a rugged metal enclosure
with a 4x20 LCD and a 2x5 tactile keypad. The Gazelle also has a serial expansion port for
additional I/O and communications. Modbus support is included.
Sample programs with
the Keil C compiler are supplied. For simple application the low cost
BASCOM basic compiler can also be used but is not as flexible as the
Keil C compiler.
The R101 is
available with LCD, Backlit LCD and PCB only.
