iWave Systems iW-RainboW-G54S is a credit card-sized SBC fitted with an OSM Size-S (30x30mm) system-on-module based on STM32MP133 or STM32MP135 Cortex-A7 SoC with up to 1GB RAM, and up to 128GB flash. Interfaces include a Gigabit Ethernet port, a USB Type-A port, an 18-bit RGB LCD display interface, and three 100-pin high-density connectors for additional I/Os. The iW-RainboW-G54S SBC is designed for industrial applications with a temperature range of -40 to +85Β°C. While itβs fitted with an OSM Size-S module, weβll also notice the carrier board has a footprint for OSM Size-M (45x30mm) and OSM Size-L (45x45mm) modules indicating it will be used with other OSM modules in the future. iWave Systems iW-RainboW-G54S specifications: System-on-Module β iW-RainboW-G54M SoC (one or the other) STMicro STM32MP133 single-core Cortex-A7 with or without Secure boot + Cryptography; for headless applications STMicro STM32MP135 single-core Cortex-A7 with or without Secure boot + Cryptography; supports LCD-TFT parallel [...]
