: |
CMM-6811 |
E-6811 is a compact trainer that is
based on the 52-pin Motorola MC68HC11 processor, and includes 32K of
battery-backed static RAM, four outputs for DC motors, a connector system that
allows active sensors to be individually plugged into the board, an LCD screen,
and an integrated, rechargeable battery pack.
This design is ideal for experimental
general experiments and also quite suited to robotics projects. The unit can
serve any number of embedded control applications and interfaces with the
Etronix application module.
