An ESP32-S3 board for vending machines with RS485, microSD card slot, optional cellular mPCIe module

LILYGO T Vending

LILYGO T-Vending is an ESP32-S3 WiFi and Bluetooth IoT board designed for vending machines with an RS485 terminal block, a microSD card slot, and support for an optional cellular mPCIe module. As I understand the board is connected to the vending machine through the RS485 terminal block to control vend motors (potentially via an additional board to control multiple motors) and a 10-pin connector for power (12V/24V), signals to/from a coin mechanism and other parts. The board also adds a Grove connector and an unpopulated 12-pin GPIO header for expansion.
