Low-power connected hardware for ESP32, nRF52, LoRa, USB-C and LiPo-based products.
I design connected hardware around the product’s radio, power and interface requirements. The scope can include ESP32 or nRF52 systems, LoRa connectivity, USB-C charging, LiPo power paths and RF-aware PCB implementation. Power budgeting and the mechanical envelope are defined early, alongside the selected module’s layout requirements.
Teams developing portable connected devices, battery-powered sensor products, wireless control hardware or custom ESP32 and nRF52 boards.
Laboratory RF tuning, firmware, compliance testing and guaranteed range or battery life are not included.
Yes, subject to the agreed requirements and scope. The portfolio includes an ESP32-S3 Smart GST Calculator and an nRF52840 navigation board. Share the interfaces, radio requirements, dimensions and power source for your product.
Yes. Charging, power-path decisions and the supply rails can be included in the hardware scope. Battery selection and current budgeting depend on your loads, operating modes and mechanical constraints.
No. Real range and battery life depend on the enclosure, environment, antenna, operating modes and firmware. Hardware architecture and layout support those goals, but measured performance requires appropriate testing.
Laboratory RF tuning, certification testing and compliance management are separate activities. This service focuses on the schematic, PCB implementation and manufacturing documentation described in the agreed brief.
