Field notes
The product description specifies UART receive and transmit pins, a 300–3,000,000 bps capture range, and a fixed device identifier. For interrupted connectivity, it describes optional TF-card retention; the cloud path uses QoS 1 acknowledgments and sequence numbers to identify missing ranges. The company also lists manufacturing test fixtures and source-code delivery among its project handoffs.
