We design a custom electronic board for your need, prepare it for production and write its firmware.
You talk to the engineer directly · reply within 24 hours · 150+ devices in the field
A control board you cannot buy off the shelf, a smaller or cheaper version of an existing board, or just an idea so far. They all start the same way: we talk about what the board has to do.
We draw the schematic, design the printed circuit board (PCB), build the prototype and write the firmware that runs on it. What we hand over is not a pile of files but a board that works on the bench.
We define the power, sensor, communication and control blocks and choose parts that are available and reasonably priced.
We lay the board out for its enclosure and operating conditions and produce production-ready files.
We write the microcontroller firmware: sensor reading, motor and relay control, displays, communication and remote updates.
We build the first boards, test them in the workshop and fix problems before series production.
We redesign the outdated, expensive or troublesome parts of an existing board and update its firmware.
Our own products and things we built for clients.
DS Mini detects the seismic wave; DS Pro builds its own communication network in the field. Board, firmware, LoRa radio and server side are all ours, with more than 150 devices deployed.
See the productA PLC-controlled test device that checks how products withstand rain, splashing water and water jets under standard conditions. Mechanics, control cabinet and software from one team.
Automation serviceA 4-relay GSM controller that switches a field water pump from a phone, with run confirmation, power-outage alerts and schedules. Board, enclosure and app are ours.
See the productShort steps and an early prototype instead of long proposals. At the end of each step we look at what is ready together.
We listen to what you want to build: on the phone, on a video call or at the workshop.
We plan the circuit, board, enclosure and firmware, and pin down the scope.
We build the first device in our workshop, bring it up on the bench and test it.
We try the device in real conditions and fix what the feedback shows.
Production-ready files, installation and firmware updates afterwards.
The person on the phone is the person designing your board. No middlemen, no sales team.
Founder · Electronics and embedded firmware engineer
Electrical and electronics engineer. Previously developed vehicle diagnostic device firmware for a US company; that firmware runs on more than 7,000 production units. At Fung IoT he owns circuit and board design, firmware and communication.
Mechanical and production engineer
Mechanical design, enclosures and assembly, production readiness. He manages the step from prototype to series production and the field installation, so the device works in the factory, not just on the bench.
Yes. Most board projects start with a conversation or a sketch on paper. Tell us what the board should do; we prepare the technical documents.
Yes, but they are tied together. Board design defines the hardware (circuit and PCB); programming defines what the microcontroller on it does. When one team does both, the board and the firmware fit each other.
Typical lead times: a simple single-sensor board reaches its first working prototype in 2–4 weeks, a control board with relay or motor drivers in 4–8 weeks, connected devices (GSM, LoRa, Wi-Fi) in 6–12 weeks. We define the scope on the first call and give you the time and price of each step in writing, so there are no surprise costs.
Once the prototype is approved, we make the board files production-ready and plan assembly with you based on your quantities.
Connected devices that collect data in the field, send it on and bring it to your screen.
We link devices in the field across kilometres, with no SIM card, subscription or internet needed.
PLC-controlled machines, custom test rigs and automation for existing machines.
Message us on WhatsApp or use the form; we reply the same working day and set a time to talk. A rough sketch, a half-finished prototype or a problem on the production line nobody has solved yet: all good starting points.
