Raspberry Pi Carrier module c/w RS485 (RPi 4 NOT included)
A WL-MIO Processor integrates the industry accepted Raspberry Pi 4 Model B (system on a chip technology) to WL-MIO. A Raspberry Pi 4 is mounted to a WL-MIO’s Raspberry PI Carrier module. The full functionality of Raspberry Pi 4 is available for users to select their optimum software application and system management environment. Electrical control of the WL-MIO’s I/O modules is via Raspberry Pi’s GPIO interface. RS-485 and HART communications are available for additional flexibility for controlling I/O devices.
Multiple Processor modules are supported in a WL-MIO system depending on the control architecture desired. Processor modules may be plugged into any WL-MIO position to accommodate existing or structured wiring designs. WL-MIO’s Processor module is hot-swappable when upgrade or replacement is required.
WL-MIO’s Process supports control software applications in these languages or application technologies:
During operation the Raspberry Pi 4’s USB 2, USB 3, and Ethernet ports are accessible. Micro-HDMI ports, micro-SD card slot, MIPI DSI display port, MIPI CSI camera port, stereo audio and composite video port are accessible for custom development purposes only.
The WL-MIO Processor consists of two components, a Raspberry Pi 4 Model B, either WL-MIO Raspberry Pi Carrier Module & RS-485, or WL-MIO Raspberry Pi Carrier Module, RS-485, and HART. Factory assembled kits combining the Raspberry Pi 4 Model B and the WL-MIO Raspberry Pi Carrier module are available.
