Software
Arduino IDE / MPINO Studio 2
Arduino IDE compatible
Works with the Arduino toolchain you already use
MPINO STUDIO2 included
Arduino code and ladder logic in one tool
Arduino + ladder logic
Build control logic faster with familiar ladder rungs
Setting up the toolchain
Using the Arduino IDE requires the ARDUINO SDK (the ILOGICS board package) to be installed. It is not required when you work in MPINO STUDIO2.
Download CableMP DOWNLOAD CABLE
Programming this board needs the dedicated download cable
The upload port on this board is a mini 5P USB socket, but the USB-to-serial conversion lives in the CABLE, not on the board. Plug in an off-the-shelf mini 5P USB cable and the PC never enumerates a port, so nothing uploads. The MP download cable is one we build ourselves — buy one and keep using it.
USB-TTL converter inside
The conversion IC sits in the connector housing
Generic mini 5P cannot be used
An ordinary cable enumerates no port and cannot upload
USB-A to mini 5P
Connects the PC's USB port to the board's upload port.
Made by ILOGICS
A dedicated cable for use with ILOGICS products.
What the cable is
* Having the conversion IC inside the housing is what sets this apart from an ordinary cable. Board end is mini 5P, PC end is USB-A, and the cable is 1 m long.
Sold separately — add it alongside the board in the purchase panel below.
Cable specification
| Item | Detail |
|---|---|
| PC end | USB-A plug |
| Conversion | USB-TTL converter inside the cable |
| Board end | USB mini 5P plug |
| Length | 1 m |
| Driver | FTDI |
Anything not listed here is available on request. We do not publish values we have not confirmed.
Installing the driver
- Connect the MP download cable between the PC's USB port and the board's upload port.
- Open Device Manager and check whether USB Serial Port (COMx) appears under Ports (COM & LPT).
- If it does not appear, install the FTDI driver from the resources section and reconnect the cable.
- In your development tool, select the same COM number Device Manager shows, then upload.
Digital input
16 isolated digital input channels
Sixteen digital input channels read external switches and sensors reliably, straight from the terminal block.
D0–D15 inputs
Sixteen digital input points in total
COM0 / COM1 commons
Two independent input groups
Optocoupler isolation
Control circuit protected from field noise
NPN / PNP sensors
Works with either sensor wiring convention
Input channel layout
* Example wiring for external switches or sensors (NPN/PNP shared)
Optocoupler isolation
The digital inputs use a bidirectional optocoupler stage (anti-parallel LEDs), so either NPN or PNP signals are read reliably, with all 16 channels referenced to COM0 / COM1.
Relay output
16 relay output channels (1a1c)
16 relay output channels switch and control external loads reliably.
D32–D47 outputs
16 relay contact output points
16 × 1a1c relays
Each output is an independent relay contact
4 outputs per COM
Each COM terminal is shared by 4 outputs
Electrical isolation
Control and output sides separated by the relay
Output channel layout
* Example wiring for external loads (relay contact output)
