Our Process

  • Define Power Budget — requirements, environment, duty cycle targets.
  • Architecture & Selection — MCU, radios, sensors, battery/harvesting choice.
  • Firmware & Profiling — optimize drivers, sleep modes, event scheduling.
  • Validation — current profiling, temperature/battery stress testing, field pilots.
  • Production — golden firmware, factory test scripts, docs & handover.
