Versatile PCB Translator for Payment Devices
Budget: $750 – $1,500 USD
Universal Translation PCB for Coin and Bill Acceptors
Project Overview
This project aims to develop a universal PCB that acts as a translation module between vending machines, bill acceptors, coin acceptors, and additional payment devices. The PCB must support various industry-standard input and output communication protocols, ensuring compatibility with vending machines, hoppers, and payment terminals.
This PCB will be installed between the vending machine and the payment peripherals, allowing multiple devices to operate simultaneously (e.g., a bill acceptor on ccTalk and a credit card terminal on Pulse/Mars).
Key Features
1. Universal Input Support
The PCB must support multiple bill and coin acceptors, regardless of their communication protocols:
Bill Acceptors: GBA-ST1+, GBA-ST2, NV9, NV10, NV200, MD100 (including bill recyclers).
Coin Acceptors: NRI G13, Comestero RM5, RM5HD, and similar models.
Additional Simple Inputs:
Pulse/Mars input for extra payment devices (e.g., credit card terminals).
GND, VCC, and configurable signal inputs for expanded compatibility.
2. Universal Output Support
The PCB must be able to send translated payment signals to vending machines, hoppers, and other peripherals:
Supported Devices:
MK4 hoppers
Soda vending machines
Other standard vending machine interfaces
Configurable Output Protocols:
ccTalk (all variations)
MDB (Multi-Drop Bus)
Pulse/Mars
Parallel
SSP
3. Power Handling & Distribution
Powered by the vending machine or bill acceptor power source (12V/24V).
Pass-through power design: The PCB must distribute power to connected peripherals.
Voltage regulation: Integrated regulators for 5V and 3.3V for logic circuits and microcontroller operation.
4. Intelligent Protocol Translation & Multiplexing
Seamless communication conversion between ccTalk, MDB, Pulse/Mars, SSP and Parallel.
Support for multiple devices at once, allowing:
A bill acceptor on ccTalk while a credit card terminal is connected on Pulse/Mars.
Multiple coin acceptors running different protocols simultaneously.
5. Microcontroller & Firmware Requirements
High-performance MCU (STM32, ESP32, or similar) with multiple UARTs and GPIOs.
Auto-detection & configuration of connected devices.
Configuration via USB, Bluetooth, or WiFi for easy setup.
6. Connectivity & Debugging
USB or Serial Port for debugging and device configuration.
LED Indicators for power, communication status, and errors.
Technical Specifications
Feature Specification
Power Input 12V/24V from vending machine or bill acceptor
Power Output Pass-through to connected devices
Microcontroller STM32, ESP32, or similar with multiple UARTs and GPIOs
Supported Protocols ccTalk, MDB, Pulse/Mars, Parallel
Interfaces UART, SPI, I2C, GPIO, USB
Configuration USB, Bluetooth, or WiFi
Status Indicators LED indicators for power, communication, and error states
Project Deliverables
PCB Design (Schematic & Layout)
Bill of Materials (BOM) with sourcing recommendations
Firmware Development to handle protocol translation and auto-configuration
Testing & Debugging Plan to ensure compatibility with real-world peripherals
User Manual & Documentation for installation, setup, and troubleshooting
In short the board must be able to be a main board for e.g an exchange machine and handle the different inputs, and have outputs for minimum 3 hoppers or other devices.
Aswell as it must be able to act as a slave and do payments in on e.g vending and soda machines..
Read the describtion, DONT BID unless you expect FULL PAYMENT OVER FREELANCER.
And DONT BID LOW TO GET IN TO TALKs with me, what you bid is what you get.
