Modular Pi (Industrial Modular Raspberry Pi)
Modular Pi is a modular controller that combines the powerful computing performance of the Raspberry Pi with industrial-grade reliability. It removes the physical limitations of standard GPIO and provides optimal stability for uninterrupted and precise control even in harsh industrial environments.
- Industrial CFNET Interface: Ensures reliability by adopting CFNET instead of the vulnerable conventional GPIO
- Flexible Modular Design: Customizable configuration by freely combining required functions (DI/DO, ADC/DAC, etc.)
- Strong Hardware Compatibility: Fully preserves Raspberry Pi native features such as USB, HDMI ports, and wireless communication (Wi-Fi, Bluetooth)
- Smart Monitoring: Real-time data logging and convenient remote control using wireless connectivity
- DI / DO: Reliable digital signal input and control output
- ADC / DAC: High-precision analog data acquisition and voltage/current output control
Specifications
- Core: Raspberry Pi 5 (2GB RAM) Included or Not Included
- Power Input: Industrial 24V DC (Internal Protection Circuit)
- Internal M.2 Slot: Supports 2280 and 2242 size modules (M-Key)

KIT DIY product
Available in two versions: Fully Assembled or DIY Kit.
The fully assembled model comes with a Raspberry Pi 5 (2GB RAM). Alternatively, choose the DIY Kit to use your own Raspberry Pi 5, giving you the flexibility to select any RAM capacity (4GB, 8GB, etc.) to suit your needs.
Development Environment
Development Method 1: CFNET-FS
CFNET-FS is an interface that allows you to use CFNET I/O as if it were a “File System.” In your program, you can control input and output by reading from or writing to specific files. This method can be used consistently across various languages, including C/C++, C#, Python, and Java.
Development Method 2: Python
You can control CFNET I/O using Python. We provide a dedicated Python module (Library) called CFRASP.py for this purpose.
