HARDWARIO Integration
The CM4 is used in HARDWARIO ecosystems for:
- TAPPER NFC Platform: The TAPPER device uses Raspberry Pi Zero 2 W as its computing core for NFC tag reading and MQTT communication.
- Gateway software host: Running HARDWARIO Cloud Connector, Node-RED, or custom integrations on a lightweight compute module.
- Local HMI/dashboard: Hosting a local monitoring interface for HARDWARIO sensor networks.
- LoRaWAN server: Running ChirpStack or The Things Stack alongside CHESTER or EMBER devices.
