5x MDB ESP32 Tiny Vending Machine

Description

5x ESP32 – Tiny Vending Machine with MDB and EVA-DTS/DEX Implementation

This project is a compact vending machine controller based on the ESP32 microcontroller. It supports the MDB (Multi-Drop Bus) protocol for communication with standard vending peripherals such as coin changers, bill validators, and cashless payment systems. The implementation also includes EVA-DTS/DEX, enabling data exchange, auditing, and telemetry for IoT-enabled vending applications.
