RDS ESP32-Based Embedded Solutions:
From Tiny Wireless Sensors to Full-Colour Smart HMIs, All Custom-Built in the UK
We have turned the humble ESP32 into one of the most versatile industrial-grade platforms available today.
Instead of treating ESP32 modules as hobbyist parts, we use them as the core of long-lifecycle, rugged, professionally engineered systems that are deployed in factories, hospitals, logistics warehouses, and smart buildings across Europe.
Board Sizes & Form-Factors RDS Regularly Delivers
- Ultra-compact: 25 × 18 mm stamp-style modules (ESP32-S3, ESP32-C6, etc.) – soldered directly onto customer motherboards
- 4.3", 5.0", and 7.0" Smart HMI panels – complete ready-to-mount units with ESP32-S3, 800×480 or 1024×600 IPS display, PCAP touch, and Wi-Fi/BT built in
- 50 × 50 mm to 100 × 80 mm custom carrier boards – designed and manufactured by RDS when more I/O is needed
- DIN-rail and open-frame industrial boxes – ESP32 plus relays, 4–20 mA inputs, RS-485, and PoE in sealed enclosures
Processing Power & Wireless Options Available
- Dual-core LX7 240 MHz (ESP32-S3) – 8–16 MB PSRAM, 8–32 MB Flash, vector extensions for lightweight AI
- Single-core 160 MHz + ULP co-processor (ESP32-C3/C6) – perfect for ultra-low sleep current (<5 µA)
- Integrated 2.4 GHz Wi-Fi 6 + Bluetooth 5 LE + Thread/Zigbee (C6) or 802.15.4 Matter-ready variants
- Up to 520 KB SRAM + octal SPI PSRAM – enough to run full LVGL GUIs with smooth animations on 7" displays
All variants are automotive/industrial grade (−40 °C to +105 °C) with locked BOM and 10-year availability.
