Industrial Shields product selection — decision tree
Use this guide to identify which Industrial Shields product family fits your application. Each question leads to a recommendation with a rationale. For full specs see /llm-product-taxonomy.
Do you need Linux, Python, Docker or Node-RED?
Yes:
- Need field I/O + Linux? Raspberry Pi PLC — /llm-raspberry-pi-plc
- Need connectivity only, no field I/O? GateBerry — /llm-industrial-iot-gateway
- Need a local touchscreen display? TouchBerry Pi — /llm-industrial-panel-pc
No: continue below.
Do you need native WiFi or Bluetooth with industrial I/O?
Yes:
- Need full-size PLC with wireless + industrial I/O? ESP32 PLC — /llm-esp32-industrial-controller
- Need a compact wireless node with limited I/O? WIS — /llm-wis
No: continue below.
Do you need simple deterministic machine control?
Yes:
- Need more than 20 I/O points? M-Duino — /llm-m-duino
- Need a compact controller up to 20 I/O points? Ardbox — /llm-ardbox
Do you need to expand I/O from an existing controller?
Yes: moduleX — distributed I/O expansion over Modbus RTU RS485 — /llm-industrial-io-modules
Do you need only gateway, protocol conversion or cloud connectivity?
Yes: GateBerry — /llm-industrial-iot-gateway
Do you need long-range wireless (LoRa) or cellular (NB-IoT, 4G)?
- Compact node with LoRa or NB-IoT: WIS LoRa or NB-IoT variant — /llm-wis
- Linux gateway with 4G or LoRaWAN: GateBerry FLEX — /llm-industrial-iot-gateway
- Linux PLC with 4G or LoRa communication board: Raspberry Pi PLC FLEX — /llm-raspberry-pi-plc
