02 / Technology

One stack. Every wireless, every sensor your product needs.

We don't bolt modules onto reference boards. Each platform is a co-designed system — RF front-end, power budget, antenna placement, and firmware all owned by us.

Cellular

  • 4G LTE Cat.1 bis (Quectel EG915Q / EG800Z, Fibocom LE271-GL)
  • Global single-SKU bands incl. Verizon, AT&T, T-Mobile, EU MNOs
  • PSM / eDRX deep-sleep for week-to-month battery life
  • VoLTE, SMS fallback, FOTA over cellular

Location

  • Multi-GNSS: GPS, GLONASS, Galileo, BeiDou
  • A-GNSS for sub-15s cold start
  • Wi-Fi / Cell-tower hybrid positioning for indoors
  • BLE beacon proximity & UWB option on demand

Compute

  • ESP32-S3 / ESP32-C6 for Wi-Fi + BT/BLE workloads
  • Nordic nRF52/nRF53 for ultra-low-power BLE
  • STM32L4/L5 / GD32 low-power MCUs
  • On-device AI on RV1106 / Kendryte for vision tasks

Sensors

  • G-sensor / IMU (ST LIS2DH12, Bosch BMI270)
  • Temperature & humidity (Sensirion SHT4x, SHTC3, HDC3020, HDC2080)
  • CO / CO₂ / VOC / PM (MQ-7, Sensirion SCD4x, SPS30)
  • Pressure, soil moisture, hall, mmWave, PIR

Imaging

  • OmniVision OS04A10 / SmartSens SC4210 CMOS
  • Low-light & IR-cut day-night switching
  • H.265 hardware encode for 720p over LTE
  • Optional edge AI: species / object / fall detection

Cloud / App

  • White-label iOS / Android apps and responsive web portals
  • Device cloud with MQTT / API integration and role-based access
  • Maps, geofences, alerts, reports, and subscription workflows
  • FOTA, fleet monitoring, and regional data hosting options
03 / Process

Six steps. One supplier. One accountable team.

Most of our European customers are tired of stitching together a Shenzhen ODM, an EU compliance lab, and a fulfillment 3PL. We do the first two and integrate with the third.

  1. 01

    Discovery

    Week 1

    We discuss product requirements and functional specifications, clarify expected sales volume and cost targets, and deliver a feasibility memorandum within the first week.

  2. 02

    Architecture

    Week 2–3

    Block diagram, module selection, MCU & sensor shortlists, antenna and power budgets, mechanical concept. Reviewed against a compliance checklist.

  3. 03

    EVT prototype

    Week 4–7

    First PCBA + tooled enclosure. Firmware up to bring-up. Internal field testing and RF pre-scan in our anechoic chamber.

  4. 04

    DVT & certification

    Week 8–12

    Design validation against your spec. CE, FCC, RED 3.3(d/e/f), ETSI EN 303 645, RoHS, REACH submitted in parallel.

  5. 05

    Mass production

    Week 13+

    PVT, then ramp. SMT, assembly, programming, calibration, packaging in our Shenzhen line. ISO 9001 / 14001 audited.

  6. 06

    Sustaining

    Ongoing

    FOTA fleet management, field RMA, BOM watch, EOL tracking, security patches. We stay on the hook for the life of the product.

04 / Compliance

European and North American compliance is the default, not an add-on.

RED 3.3(d)(e)(f) became mandatory in August 2025. We've been designing against ETSI EN 303 645 since 2023. You inherit that work.
