Description
The LilyGO T-Vending is an industrial-grade IoT development board built around the Espressif ESP32-S3-WROOM-1 module. It combines a powerful dual-core Xtensa LX7 processor with integrated 2.4GHz WiFi and Bluetooth 5.0, providing a complete wireless system-on-chip solution. The board’s standout feature is its integrated, galvanically isolated RS485 transceiver (RSM485MT5V), which offers 3000V of isolation to protect the sensitive MCU from high-voltage transients and ground loop noise common in industrial settings.
Designed for expansion, the board includes a PCIe interface socket compatible with LilyGO’s T-PCIE series modules, allowing developers to seamlessly add cellular (4G/LTE), GNSS, or other PCIe-based connectivity. This makes the T-Vending ideal for building gateways that bridge local RS485 sensor networks to cloud platforms via WiFi, Bluetooth, or cellular backhaul. The board supports a wide RS485 baud rate from 1200 to 128000bps and includes an isolated 5V/50mA power output for external sensors.
