FEATURES
The BOT40 and BOT40-II Controller Boards are virtually identical,
except that the original BOT40 has H-bridges
and high-current drivers, plus room for interfacing 8 R/C style servos,
while the new BOT40-II board forgoes the h-bridges and drivers in favor of
directly interfacing up to 29 R/C style servos.
The new board is specifically designed to support our
Bot-Cop Multi-Servo Controller and
Walking Machine chips.
The BOT40 Controller Boards are distinquished by having:
large prototyping areas
high configurability
significant amounts of cpu protection built onto the pcbs.
Typical applications include:
small robot controllers
general embedded controllers
servo controllers
motor controllers
closed-loop control systems
robot walkers
motion control and animatronics
mini-sumos
Both boards are made to meet mini-sumo size limits.
