This is an open source project dedicated to implementing the MDB (Multi-Drop Bus) protocol for cashless vending machines, using ESP32-S3 as the main platform and KiCad for PCB design. The MDB protocol is widely used in vending machines for communication between devices, enabling integration with cashless payment systems.

Implementation of the MDB protocol for communication with vending machines; Support for integrating cashless payment systems into vending machines; Utilization of ESP32 as the hardware platform, offering flexibility and advanced IoT features; PCB design done in KiCad, facilitating production and customization of the hardware; Support for EVA DTS (Electronic Vending Audit), allowing remote monitoring and control of machines.
