Industrial ESP32-S3 board with RS485 and CAN and external SMA antenna - Wi-Fi, Bluetooth, DIN Rail
Industrial controller based on the ESP32-S3 chip, equipped with isolated RS485 and CAN interfaces as well as Wi-Fi and Bluetooth 5 (LE) connectivity. Version ESP32-S3-RS485-CAN-U features a factory-active external antenna with an SMA connector, ensuring better wireless communication range.
Key features:
- ESP32-S3 Xtensa 32-bit LX7 Dual-Core processor clocked at up to 240 MHz.
- Wi-Fi 2.4GHz and Bluetooth 5 LE connectivity.
- External Wi-Fi/Bluetooth antenna with SMA connector.
- Factory-active external antenna.
- Isolated RS485 interface with automatic transmission direction control.
- Isolated CAN interface with TVS and ESD protection.
- Power supply 7-36V DC via screw terminal.
- Built-in PCF85063 RTC real-time clock.
- Digital signal isolation and power isolation.
- Surge, ESD, and TVS protection.
- Housing for mounting on a standard DIN rail.
- LEDs indicating power and RS485/CAN activity.
Multi-level isolation and circuit protection
The controller is designed to operate in demanding industrial environments. The galvanic isolation used separates control circuits from interference, while TVS and ESD protections shield communication interfaces from surges and electrostatic discharges.
Description of interfaces and terminals
The controller is equipped with screw terminals for RS485, CAN, and power supply buses. Programming and diagnostics are performed via a USB Type-C port, while wireless communication is provided by a factory-active external antenna with an SMA connector.
