Overview
The LILYGO T-Vending is an ESP32-S3-based development board purpose-built for vending machine control and industrial RS-485 communication. At its core is an ESP32-S3-WROOM-1 running dual-core Xtensa LX7 at 240MHz. The onboard MAX13487E provides half-duplex RS-485 communication at up to 500 kbps with ±15kV (1500V) ESD protection, enabling reliable deployment in noisy industrial environments. A T-PCIE SIM expansion slot enables cellular connectivity modules (sold separately), and a Grove connector facilitates quick sensor integration. Reset and boot buttons support development workflows. The board targets vending machine operators, industrial automation developers, and IoT integrators needing ruggedized serial communication with wireless control capability.
