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
- CCore: 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)
- Expansion: Supports CFNET I/O Module Slots
- Protection: Reinforced design for EMI / Noise / Surge with I/O Isolation
The following image shows a Modular Pi main unit (Model: CPi-5000BR) with CFNET I/O modules installed.
Internal M.2 Slot: Supports 2280 and 2242 size modules (M-Key). The M.2 SSD shown installed below is for demonstration purposes only and is not included with the product.

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.
