SQC485Iv2
Convert industrial RS485 / Modbus data into long-range LoRa — with protection rugged enough for real installations.
±70 V bus-fault protection, ±12 kV HBM ESD, true fail-safe receiver and thermal shutdown.
Multi-stage protection validated to survive up to 30 V accidentally applied across A / B.
Semtech SX1262, AS923-1 for the Taiwan 920–925 MHz band; point-to-point, point-to-many or mesh.
8–30 V DC industrial supply or 5 V USB-C, with automatic source selection.
USB-C for programming and console; internal-antenna BLE 5 for wireless provisioning.
Industrial operating temperature range for harsh environments.
