Hw-133-v1.0 Datasheet Upd Here

Always measure the output with a multimeter before connecting sensitive electronics (like an Arduino or ESP32) to ensure the voltage isn't set too high from the factory.

The Hw-133-v1.0 was a compact, low-power communications module designed for edge devices — the datasheet boasted a blend of efficiency and ruggedness. Nominal supply was modest: 3.3V, the kind of single-rail pragmatism gardeners of embedded systems favored. The RF front end could handle a surprising range of frequencies, the chart bragged, and the integrated antenna port was engineered to cut losses in tight enclosures. Leo traced the antenna footprint with his finger as if mapping a route. Hw-133-v1.0 Datasheet

: Despite being rated for 3A, users report significant heat generation when pushing past 1.5A. For high-current scenarios, adding a small heatsink or ensuring active airflow is essential to avoid thermal shutdown. Voltage Sensitivity The RF front end could handle a surprising
