Introduction
PES-2403
PES-2403, stepper motor controller, is a smart expansion board for PHPoC boards. With this board,
you can easily control various stepper motors.
Highlights of PES-2403
bi-polar stepper motor controller
input voltage: 4 ~ 18V [DC]
drive: full-step(two phases on), half-stepping
※ Caution: PES-2403 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.

1. Stepper motor & Power port
Stepper motor & Power port is 1-by-6 terminal block with 5mm pitch.

M1+, M1-, M2+, M2- connect to stepper motor
VM, GND connect to power
Connecting to a bipolar stepper motor
PES-2403 is a controller for bipolar stepper motors. An example of connection with a bipolar stepper
motor is as follows:

Connecting to a unipolar stepper motor
If you want to connect a unipolar stepper motor to PES-2403 refer to two examples below.
Supplying power
GND and VM are input port of supplying power(DC 4 ~ 18V) to run motors. Supplying power
through this port is positively necessary. Check the DC polarity when you input the power.

2. Digital input port
This port is used to connect limit switches and cannot be used for other purposes.
An example of connection with limit switches is as follows:
G means ground and all ground pins are connected each other
0, 1, 2 and 3 are the index number of input ports and all of them are pulled up
3. SLAVE ID Switch
A slave ID is used when PHPoC board identifies each smart expansion board. So, each smart
expansion board, which is connected to a PHPoC board, should have a unique slave ID. The slave ID
can be set one of the numbers from 1 to 14 by 4 DIP switches as follows:

4. LED
PES-2403 has 2 status LEDs. The one, on the top of the board, is connected to 3.3V and the other
one, on the bottom of the board is connected to 5V. The operations of both LEDs are the same and
they are as follows:
about ID setting
state operation
normal repeat On/Off in every second
abnormal blinks very quickly
about running motor
state operation
ready repeat On/Off in every second
running shortly turned on 4 times in every second
locked shortly turned off 4 times in every second
out of control off

How to Use
The steps for using PES-2403 are as follows.
1. Connect to a PHPoC board
PES-2403 cannot be used alone. Be sure to connect to PHPoC board.
2. Install Software (IDE)
PHPoC Debugger is a software which is used for configuring PHPoC products and developing
PHPoC script. It is required to install this software on your PC because PES-2403 must be controlled
by PHPoC.

3. Use SPC Library and Sample Codes
The SPC library is for smart expansion boards such as PES-2403. This library makes it easy for you to
use smart expansion boards. Refer to the manual page of SPC library for more information.

Commands
You can use spc_request_dev or spc_request_sys function when setting or using a smart expansion
board.
spc_request_dev($sid, $cmd)
spc_request_sys($sid, $cmd)
$sid: slave ID
$cmd: a command string for setting and controlling stepper motors
Common Commands of Smart Expansion Boards
Common commands can be used with spc_request_sys function and a list of the commands is as
follows:
Command Option Description
get did get a device ID
get uid get a unique ID
