The RDS Approach: Industrialising the ESP32

The ESP32 has evolved from a simple Wi-Fi chip into a multi-core powerhouse (like the ESP32-S3 and P4) capable of driving high-resolution displays and lightweight Edge AI. RDS supports this evolution by supplying and integrating professional development kits designed for longevity and reliability.

1. Power over Ethernet (PoE) Solutions

In an industrial setting, Wi-Fi can be unreliable and running separate power cables is costly. RDS specialises in PoE-enabled ESP32 platforms that provide:

• Single-Cable Connectivity: Delivering both high-speed data and DC power over a standard Cat6 cable.
• Galvanic Isolation: We prioritise isolated PoE designs (such as those based on the ESP32-POE-ISO standard). This protects your internal electronics from voltage surges and ground loops common in factory environments.
• High Power Delivery: Our solutions can manage the power requirements of the ESP32 plus attached peripherals like OLED Displays or sensor arrays, all drawn directly from your network switch.

2. Smart HMI Development Kits

RDS supplies integrated "Smart Display" kits where the ESP32 is already bonded to a high-quality panel. These kits act as the perfect "ready-to-code" starting point:

• Display Range: 1.4" AMOLED circular displays to 7.0" industrial IPS panels.
• Integrated Touch: PCAP (Projected Capacitive) touch controllers pre-integrated and calibrated.
• Edge AI Ready: Utilising the ESP32-S3’s vector instructions for voice recognition or simple gesture control.

How RDS Helps Developers Build Systems

We bridge the gap between a "working prototype" and a "deployable product." Our engineering team provides the technical scaffolding that developers need to cross the finish line:

Custom Carrier Board Design

Dev kits are great for desks, but rarely fit into a final enclosure. RDS designs bespoke carrier boards that host the ESP32 module while adding industrial-grade IO (RS-485, 4-20mA inputs) and ruggedised connectors (M12 or screw terminals).

Thermal & Mechanical Optimisation

PoE components and high-brightness displays generate heat. We provide thermal simulation and mechanical design to ensure your ESP32 doesn't throttle its performance when sealed inside an IP65-rated enclosure.

Vertical Integration via Volex

As part of the Volex Group, we provide the ultimate "Box Build" service. While you focus on the ESP-IDF or Arduino code, RDS and Volex handle:

• The Interconnects: High-quality, industrial-grade PoE cabling and internal harnesses.
• The Housing: Custom-moulded or machined enclosures.
• Compliance: Managing the EMC and safety testing (UKCA/CE) required for commercial deployment.

Software Support & Longevity

We don't just ship hardware. RDS provides Board Support Packages (BSPs) and driver libraries for our display ranges, ensuring your firmware team can get the GUI running in days, not months. Most importantly, we guarantee long-term availability (typically 10+ years), so your design isn't rendered obsolete by a chip revision.
