Stop cobbling together gateways, radios, and CAN adapters. The CRATUS INTERCAL8 Wireless Dual CANBUS Bridge “ICL8-WC182” does it all, wired and wireless, as one highly integrated subsystem. It is ready for integration into larger systems or standalone applications as one ruggedized package, ready for the field. It features dual wireless links, WiFi or Proprietary wireless mode.
Engineers building CAN FD networks today are forced to piece together multiple components — each with its own power requirements, firmware stack, and integration risk.
See why engineers who've tried the fragmented approach keep switching to a single, purpose-built platform.
| Capability | Cratus DW-DCAN Board | Multi-Board Approach | Generic CAN Gateway |
|---|---|---|---|
| Dual CAN FD channels | ✓ Both channels, simultaneous | Possible — extra board | Usually 1 channel |
| Wireless (Wi-Fi + P2P radio) | ✓ Dual Wireless Onboard | Add-on module required | x Not included |
| Power conditioning (9–36 V) | ✓ Onboard SMPS + LDO + isolation | x Separate PSU needed | x External supply only |
| OTA firmware updates | ✓ Dual-bank, over Wi-Fi | Per-device, manual | x Not supported |
| Hardware node addressing | ✓ 64 addresses via DIP switch | x Firmware only | x Firmware only |
| RJ45 daisy-chain (power + CAN) | ✓ Single cable per node | x Separate power + signal runs | x CAN only, no power |
| ESD protection (±8 kV HBM) | ✓ On both CAN buses | Varies by component | Usually ±2 kV |
| Industrial temp range (–40 to +85 °C) | ✓ Full range, all components | Depends on selection | Often 0 to +70 °C |
| Time to first packet | ✓ <5 minutes, no firmware config | Hours to days of integration | 30–60 minutes |
Purpose-built for demanding field deployments — so you spend less time on integration headaches and more time shipping product.
All parameters unless otherwise noted apply over –40 °C to +85 °C after thermal stabilization.

Engineered for the most demanding real-world deployment environments across industries.
Every subsystem engineered to work together — from the power rail to the wireless antenna.
Imagine a fleet of machines on a factory floor. Each machine hosts one Cratus board. The boards communicate over CAN FD with local sensors and actuators. Each board relays live telemetry wirelessly to a central gateway. The system also pushes data to your cloud dashboard over Wi-Fi — and handles OTA firmware updates automatically.
No complex configuration. Hardware does the heavy lifting so your team hits the ground running.
Plug in 9–36 VDC via screw terminal or the RJ45 daisy-chain. The board's ideal-diode controller protects against reverse polarity and surges — the moment power is applied, the system begins bringing up rails automatically.
Flip the 6-position DIP switch to your desired node ID (0–63). No firmware changes, no tool required. Every board in your network gets a unique address in seconds.
Daisy-chain boards with Cat5e/6 patch cables. The MCU auto-initializes both CAN FD channels and the wireless modules come online within 300 ms. Your entire network is live.
CAN FD data flows between nodes. Telemetry is relayed via ESP-NOW to a gateway, and Wi-Fi pushes live data to your cloud dashboard or MQTT broker. Everything just works.
New firmware? Push an OTA update over Wi-Fi to every board in the field simultaneously. Dual-bank boot ensures a safe rollback if anything goes wrong. Zero downtime.
“We replaced three boards — a CAN gateway, a wireless module, and an external PSU — with a single Cratus board. Integration time dropped from three weeks to two days. It just works.”
