Software Specifications

Model Selection

BL118 Node-RED Edge gateway, designed for secondary development, adopts a flexible architecture that allows users to select different SOM boards to configure various ROM and RAM combinations. By integrating different X and Y boards, it supports a wide range of I/O combinations to meet the needs of diverse application scenarios.

Product Naming Convention:

Host Model–SOM Model–X Board Model–Y1 Board Model–Y2 Board Model

For example: BL118-SOM334-X1

BL118 indicates host model with 2 Ethernet ports, 2 USB 2.0 ports, an X board using a 2x5 PIN interface, and no Y boards.

SOM334 specifies an eMMC of 4GB, 512MB DDR4 RAM, and a wide temperature range of -40°C to 85°C.

X1 indicates that the X board provides 4 channels of RS485.

To indicate additional modules:

Add "W" after the host model for Wi-Fi support (e.g., BL118W-SOM334-X1).

Add "L" after the host model for 4G module support (e.g., BL118L-SOM334-X1).
