Introduction
PES-2405
PES-2405, stepper motor controller Ⅱ, is a smart expansion board for PHPoC boards. With this
board, you can accurately control various stepper motors.
Highlights of PES-2405
bi-polar stepper motor controller
driving modes: micro step(maximum division rate: 1/32)
motor voltage: DC 4 ~ 18[V]
maximum current on each coil: 1[A]
current comsumption: approximately 30[mA]
※ Caution: PES-2405 requires a PHPoC board which has a firmware 1.3.0 or higher version.
What is the Smart Expansion Board?
A smart expansion board has own devices and firmware unlike the other
expansion boards. This board communicate in a master-slave protocol through
the designated port. Two or more smart expansion boards can be connected to
one PHPoC board and each of them required to be setting a slave id.
