Duvall Espresso Revolutionizing Coffee Brewing: Embedded Expertise Brings Patented Technology to Life

Duvall Espresso is an American coffee machine manufacturer founded on the principle that controlling flow rate is key to unlocking the flavor potential of coffee. Their FC-1 machine provides baristas a high level of control to extract the best from any coffee.

Duvall Espresso worked on the FC-1 project with Professional Software Associates, Inc. (PSA), a long-standing Toradex partner, that provides end-to-end services for IoT product development, including hardware design, firmware development, and connectivity.

Highlights

Cutting-edge Coffee Brewing Technology with Toradex at the Core

PSA's embedded systems expertise, including proficiency with Toradex System on Modules (SoMs), proved crucial for Duvall Espresso. Since late 2023, PSA has been working with the startup, whose patented technology delivers consistent flavor profiles independent of grind size, tamp, and dose, to move their product from prototype to market.

High Performance with Power Efficiency

The Colibri iMX7D is a high-performance and affordable System on Module featuring two power-efficient Arm® Cortex-A7 cores and an M4F microcontroller.

HMI Flexibility

PSA implemented improved human machine interface (HMI) screens for better user experience built in Electron with HTML5.

Peripheral Interface Management

The module’s onboard Toradex BSP manages all peripheral interfaces and communication protocols, including RS-232, Ethernet, Flash, UART and Modbus.


At Duvall, Toradex’s SoM was key to accelerating development, reducing risks, and bringing our product to market faster and more affordably. Their recommendation of PSA, Inc. as a trusted development partner provided invaluable support in achieving production readiness.

Duvall Espresso and PSA’s Journey with Toradex


  • The Challenge: Implement Patented Coffee Brewing Technology

    The customer needed to find a trusted engineering partner to certify and successfully launch to market a brand new coffee machine, ensuring its high competitive advantage. Previous experience with engineering companies outside the Toradex partner ecosystem had resulted in performance issues.


  • The Objective: Create a Market-ready Product

    The goal of the customer was to refine the firmware of the commercial coffee machine prototype in order to produce a market-ready product and provide the highest performance and UX with cutting-edge technology. Toradex recommended working with PSA, as a proven Toradex partner with extensive experience in product engineering.


  • The Solution: Toradex Colibri iMX7D System on Module

    Having a firmware MVP with limited functionality, PSA provided significant enhancements to ensure failure-free operation and consistent control for the machine powered by a robust and feature-rich Toradex Colibri iMX7D SoM.

    PSA thoroughly examined the firmware source code and recreated the development environment to empower the system with the following features:
    • Optimized business logic for correct system operation
    • Functional stability regardless of external factors
    • Possibility of firmware updates
    • Synchronization between devices comprising a coffee machine
    • Improved HMI screens for better UX

  • The Outcome: High Performance, Easy-to-use and Extensive Customization

    As a result, the performance issues were eliminated and the client got an easy-to-use coffee machine with extensive customization options for coffee extraction without compromising performance. While the product is undergoing certification, PSA continues to support its further upgrades before the market launch.

At PSA, we believe that exceptional solutions are crafted by exceptional minds, powered by innovative products like Toradex System-on-Modules (SoMs).

Thanks to the extensive feature set of Toradex Colibri iMX7D, we’ve managed rapid and trouble-free firmware redesign promoting superior performance of the final product. Leverage of Colibri became a cornerstone for us to help the client implement their cutting-edge technology for coffee extraction while shortening the brewing cycles.
