Firmware
Battery ESP32 sensor with telemetry
Battery power, I2C/SPI sensors, Wi-Fi transport and OTA updates.
The prototype runs standalone for a week and updates over the air.
About
An R&D studio for early-stage hardware
We take a device idea to a working prototype: firmware, board, app and handover docs another team can pick up.
Mission
We remove technical uncertainty at the start: instead of a sales call you get a scoped estimate with risks, timelines and a clear go / no-go.
Principles
- Fixed scope: work ends at the prototype, not in an open-ended contract.
- Handover-ready: sources, builds and notes another engineer can continue.
- Honest gates: nothing moves forward until the previous deliverable is documented.
