Industries
The connected-product categories we build for.
D3 Engineering, part of D3 Innovation in Penang, Malaysia, builds the firmware and embedded software behind connected hardware across the categories below — often alongside D3 Innovation's manufacturing capability, from board bring-up through production firmware.
Communication
Wireless and connectivity modules — Bluetooth, Wi-Fi, LoRaWAN, and cellular — with firmware tuned for real-world range, power budget, and regulatory certification.

Questions about industries we serve
What industries does D3 Engineering specialize in?
Communication, Lighting, Energy/Industrial/Building, Smart Home, Networking, and Agriculture & AgTech — see the categories above for what we typically build in each.
Do you only work with large manufacturers, or also early-stage hardware startups?
Both. We work with established manufacturers modernizing existing product lines and with early-stage teams taking a first hardware product from concept to shipped device.
What if our product doesn't fit neatly into one of these categories?
Most projects still fit even if they don't map neatly onto the categories above. Tell us about your product and connectivity requirements and we'll tell you honestly whether we're a good match.
Do dedicated industry pages affect which projects you can help with?
No — the six categories reflect where most of our engagements land, not a hard boundary. If your product spans more than one, or none exactly, get in touch and we can talk it through.
