Design & Manufacturing.

Electronics for Communication Systems.

Design and manufacture of circuit boards that talk to each other.

Whether it’s a kitchen monitor sending status updates to your phone or industrial equipment streaming performance data to the cloud, connected electronics are the norm, not the future.

At Winter and Smith, our clients come to us because they want their electronics to do more: to be monitored, managed, and maintained from anywhere.

We have experience with the following

  • Mobile 2G
  • Mobile 3G
  • Mobile 4G
  • RS485 & Modbus
  • RS232
  • Bluetooth and Bluetooth Low Energy
  • Zigbee
  • Xbee 868 & 2.GHz Mesh
  • Radiocrafts 868Mhz
  • Infra Red Data (IrDa)
  • Ethernet
  • Wireless Ethernet

Bluetooth

Local wireless control without the complexity

Bluetooth is our go-to for products that need quick, direct control via smartphone or tablet. We use it in systems where users want real-time interaction without needing a full Wi-Fi connection. It’s ideal for configuration, local diagnostics, or toggling settings when physical access is limited.

Wi-Fi

High-speed data and cloud Integration

Wi-Fi (wireless Ethernet) enables always-on internet access for products that push data to cloud platforms, receive over-the-air updates, or need to be monitored in real time. We design Wi-Fi into appliances, dashboards, and sensors where bandwidth and reach matter,  using proven chipsets and secure network stacks.

Mesh Networks

Reliable coverage in complex or large environments

For projects spanning large physical areas, like building automation or sensor grids, we implement Zigbee or Xbee mesh networks. Each node in the mesh acts as a repeater, creating a robust, scalable system that doesn’t depend on a single hub. These networks adapt to signal interference and reroute automatically if one link fails.

Modbus

Industrial-grade communication

Modbus remains a rock-solid option in industrial environments. Whether it’s RTU over RS485 or TCP over Ethernet, we’ve integrated Modbus into embedded systems to ensure compatibility with SCADA platforms, PLCs, and legacy equipment. It’s simple, fast, and widely supported across automation hardware.

In-house development for PCBs that talk

Unlike other companies that outsource their PCB manufacturing, Winter & Smith designs and builds PCBs in-house.

  • Tailored to you – We can create custom PCBs specifically for your needs, ensuring that all components and connections are optimised for integration and long-term performance.

  • Higher quality – By controlling the entire production process, we ensure that every board meets high-quality standards

  • Faster problem solving – If an issue arises, we can quickly modify and produce updated PCBs without waiting for external suppliers, getting your systems back up and running
