NTRODUCTION
The Coyote single-board computer gives OEM designers
extremely low-cost embedded control for high-volume applica-
tions. Two standard models—one with Ethernet, one without—
feature the Rabbit
®
3000 microprocessor running at 29.4 MHz,
with standard 256K flash and 128K SRAM. These compact
boards are rich with the I/O (including one A/D input and two
D/A outputs) designers need for embedded control and monitor-
ing applications, and the Coyote's compact board size of 3.95" ×
3.95" (100 × 100 mm) is easily mountable in standard 100 mm
DIN rail trays.
Customized BL2500 models can be manufactured in volume in
OEM versions to user-specified configurations. Pin-compatible
RabbitCore modules allow multiple configurations of the Coyote
with Ethernet and memory options.
