Deep Expertise Across Four Industrial Domains
Each solution is built on our proven STM32 gateway platform, customized to solve your industry-specific pain points with production-ready hardware and firmware
Industrial Automation
Our STM32 edge gateways realize Modbus RTU/TCP multi-slave polling, isolated RS485 signal conditioning, and real-time SCADA data upload via Ethernet / cellular / Wi-Fi. We solve long-distance bus anti-interference optimization with galvanic isolation, deterministic FreeRTOS real-time scheduling, and local edge data caching during network outages — ensuring zero data loss even when cloud connectivity drops.
Smart Energy
Custom embedded monitoring gateways for power distribution, solar storage and smart meters. Collect 4-20mA analog voltage/current data with 16-bit ADC precision, support wide-temperature outdoor deployment (-40~85℃), secure TLS MQTT energy data upload, and local fault alarming without cloud dependency. Our gateways run unattended for years in remote substations and solar farms with watchdog-supervised self-recovery.
IoT Devices CORE
Full-stack industrial IoT gateway & sensor node solutions based on STM32 F4/H7/L4. Realize multi-protocol conversion (Modbus, CAN ↔ MQTT), triple-network redundancy (Ethernet / Wi-Fi / BG95 cellular) with automatic failover, hardware AES-256 encryption via STM32 crypto peripheral, secure signed OTA with rollback protection, and X.509 device identity authentication for mass production. Every gateway ships with factory-provisioned certificates and hardware unique ID binding.
Custom Electronics
Bespoke industrial hardware from schematic & multilayer PCB layout (4/6-layer) to mass-production BOM optimization, DFM review and surge protection design. Matched with self-developed FreeRTOS firmware, full testing report (EMC, thermal, burn-in) and factory burning tool delivery. We bridge the gap between prototype and mass production with production-ready designs that pass certification on first submission.
