Custom Hardware Design
We design the device, write the firmware, and get it manufactured. Direct factory relationships in Shenzhen — built over years, not through a broker. From a napkin sketch to mass production, or from your existing prototype to a factory-ready product. We handle the full path.
Two Ways In
Whether you start with a problem or a prototype, we meet you where you are.
You Have a Problem
Concept → Prototype → Production
You describe what needs to be measured, monitored, or controlled. We design the hardware specification, select components, prototype the device, write the firmware, test in your environment, iterate, and take it to production. You get a working product — not a schematic you need to figure out yourself.
You Have a Prototype
Prototype → Production-Ready → Manufacturing
We take your working prototype through PCB and enclosure design, firmware refinement, field trials and manufacturing handover. Deliverables and ownership of design files, firmware, BOMs and test fixtures are agreed before work starts, including any third-party component restrictions.
In-House Firmware
We write every line of firmware ourselves. No outsourcing, no handoffs between hardware and software teams.
ESP32 & ESP8266
- ESP-IDF for production-grade firmware
- FreeRTOS for real-time multitasking
- WiFi, Bluetooth, and ESP-NOW communication
- Deep sleep and power management for battery devices
- OTA updates for field-deployed devices
MicroPython
- Rapid prototyping and proof-of-concept
- Sensor integration and data collection scripts
- Quick iteration during design phase
- Transition to ESP-IDF/C++ for production when performance demands it
What Our Firmware Does
- Sensor reading, calibration, and filtering
- Local data buffering when connectivity drops
- MQTT, REST, and WebSocket data transmission
- Modbus for industrial sensor networks
- Alert logic and threshold monitoring on-device
Manufacturing & Supply Chain
Direct factory relationships in Shenzhen — years of working together, not a directory listing.
PCB & PCBA
We work directly with Shenzhen factories for PCB fabrication and assembly. From single-board prototypes to production runs. Component sourcing, BOM optimization, and quality inspection handled as part of the engagement — not passed off to a third party.
Enclosures
Direct relationship with Szomk for plastic enclosures — standard catalog housings for fast turnaround, or custom-molded designs for specific form factors. IP-rated enclosures for outdoor and industrial deployments. We match the enclosure to the environment.
Prototyping to Mass Production
- Rapid prototyping with fast-turn PCB services
- Small batch runs for field testing (10-100 units)
- Production runs with factory QC
- Component sourcing and BOM cost optimization
- Packaging and logistics coordination
Quality & Compliance
- Agreed inspection and acceptance criteria for production batches
- Compliance scope and external test/certification responsibilities defined upfront
- Environmental and firmware testing against the operating requirements
- Manufacturing handover with BOM, design files and test documentation
- Field-update, calibration and support arrangements agreed for the device
What We've Built
Hardware projects from our own product line and client engagements.
LoggerDaisy Sensors
5+ Years — Environmental Monitoring Hardware
Custom sensor devices for temperature, humidity, air pressure, CO2, ethylene, and VOC monitoring. The proprietary VOCA sensor detects CO2 and volatile organic compounds across broad temperature ranges. Deployed in warehouses, cold storage, greenhouses, and transportation fleets. Medical integration with Jumper Medical oximeters.
Zeento.Cloud Devices
Incubated — Cold Chain Sensor Hardware
Hardware design work for the incubated Zeento.Cloud initiative. Connectivity, enclosure protection and temperature range are specified and tested for the intended facility. A design target is distinguished from a completed environmental qualification or production deployment.
Sensobot
WebIt 2014 IoT Hackathon Winner
Sensor-enabled gear for drones — real-time environmental data collection from aerial platforms. Custom hardware integration with ESP microcontrollers and specialized environmental sensors. Won the IoT hackathon for innovative sensor integration.
