When a miniature control system is a must, along with
a variety of I/O options, customers choose Micromint's RTC
stacking-board product line as a proven performer. With our
complete line of development system tools, using them is as
simple as R-T-C.
RTC controllers can be used stand alone or in a stacked architecture
consisting of a base processor with a variety of I/O expansion
boards. Together, they can provide a collective control solution
in as small as a 3.5" x 3.5" footprint.
Users choose among six different processor types for their
favorite programming environment. Then, if the processor board's
considerable onboard I/O isn't enough, they choose from more
than a dozen different I/O expansion boards to add on top
of the processor boards. Whatever the application, whatever
the voltage and I/O constraints, a Micromint RTC stack results
in an unbeatable price-performance package every time.

Before there were RTC and module-based controllers,
there was Micromint BCC. Simply translated as Basic Computer
Control, BCC offers a basic, rugged, low-cost, yet very expandable
edge-card and motherboard-style system. Like the RTC, a user
chooses among the processor boards and then selects among
an assortment of expansion cards to create custom-tailored
control solutions. Because of their ruggedness and versatility,
it is no wonder that thousands of BCC systems are in use all
over the world today.
BCC card cage systems can be constructed as 4-slot, 8-slot,
or dual 8-slot 19" rack units. Various power supply options
allow the BCC system to go virtually anywhere.
