Electronic Boards for Coffee

Compact board for managing pod or capsule coffee machines with 2/3 buttons, capable of handling internal consumption counters as well as capacitive or mechanical buttons. This board also features an interface for connecting additional devices such as Wi-Fi+BLE and RFID modules compatible with the DuoLocker system.
Thanks to integration with DuoLocker, it is possible to implement an advanced RFID-based debit system, which lets you associate each user with a personal card to enable dispensing, monitor consumption, and manage credits or subscriptions securely and traceably.

In addition, the board is equipped with PID control for boiler management, ensuring high precision in temperature regulation. Using PID is essential to keep water temperature stable and achieve consistent, high-quality coffee extraction (learn more).

Board dedicated to the professional HoReCa espresso market, capable of managing up to 3 groups and a steamer. The board connects to an external keypad or a TFT display from 2.4" up to 4.3" and allows firmware updates via USB port or Wi-Fi.
This platform can be expanded from 2 to 4 groups on request and is prepared for add-on modules such as Wi-Fi+BLE and RFID, compatible with the DuoLocker system.
Thanks to integration with DuoLocker, the board supports RFID-based debit systems that make it possible to manage users, credits and consumption securely and traceably.

It is also equipped with PID control for managing boilers and groups, ensuring precise and stable temperature regulation — essential for consistent, quality espresso extraction.
Available with either a linear or a switching power supply to suit different professional integration needs.

Kit for an on-demand electronic dosing grinder (basic version) consisting of a 85–265 VAC power board with switching PSU and motor/fan control, paired with a display board from 2.4" up to 4.3" with optional multicolor LEDs and Start/Stop button detection.
The system provides interfacing with the scale connected to the portafilter for real-time espresso dosing, supports OTA (Over-the-Air) updates and Bluetooth connectivity for linking with a smartphone app.

• Dynamic QR code.
• Customizable multilingual display UI.
• Grind time adjustment to hundredths of a second.

The system can be connected to DuoLocker to control coffee in debit mode, ensuring maximum protection for the roaster and enabling simple, secure and low-cost monitoring of customers’ consumption thanks to RFID technology.

The professional scale board developed by Duolabs can weigh up to 50 kg with outstanding 0.1-gram accuracy. Thanks to the UART connection it can be linked to external devices, ensuring stability, reliability and consistent calibration over time.
The board is designed for integration with TFT displays from 2.4" up to 4.3", making it suitable both for embedded applications and as a stand-alone device. Its technical features make it ideal for implementation in a grinder-doser (for precise control of ground-coffee doses), a coffee machine (to manage weighing and real-time control of extractions), or as an independent scale in professional environments where reliability and precision are essential.
