Aiming at bringing the next generation of HMI, reTerminal is offered as being fully-featured, designed, and certified for IoT developers to build industrial applications based around the Raspberry Pi Compute Module 4 (CM4).

“With the great open-source ecosystem dedicated to the Raspberry Pi,” says Albert Miao, CTO at Seeed, “we are launching reTerminal to enable IoT developers to transform their Raspberry Pi-based projects and solutions into real-world industrial use.”

Traditionally, HMIs are stand-alone, isolated user interface terminals as a part of a machine that are deployed by Original Equipment Manufacturers (OEMs). As IoT is influencing the way all the connected devices operate with a dramatic increase in the amount of data and vertical connectivity, says the company, future HMIs must offer intuitive extensibility for developers to apply AI and machine learning algorithms at the edge that can learn from all the data generated from IoT sensors and adapt to the ongoing behavior of the operator.

reTerminal is offered as a future-ready HMI device in a compact form factor measuring 140 x 95 x 21 mm. With an industrial integrated design, reTerminal is durable and resistant to environmental contaminants in real-world scenarios.

As an HMI device, it features a 5-inch, 1280 x 720 capacitive touchscreen with a five-point multi-touch. It also comes with a Raspberry Pi Compute Module 4 with 4 GB RAM and 32 GB eMMC mounted on a true industrial-grade carrier board. It supports an embedded Linux Debian operating system with all the drivers installed on board, which ensures that every hardware feature is readily available for any standard development tool.

The device also offers extensibility designed for further development in vertical industrial scenarios. It has wireless connectivity with dual-band 2.4/5-GHz Wi-Fi and Bluetooth 5.0 BLE and security features such as a cryptographic co-processor with secure hardware-based key storage. Built-in modules include an accelerometer, light sensor, and a Real-Time Clock (RTC).

Other features include a Gigabit Ethernet Port, dual USB 2.0 Type-A ports, a high-speed expansion interface, and rich I/O for greater expandability. The 40-pin Raspberry Pi-compatible header on the reTerminal opens it for a wide range of IoT applications. Furthermore, various extensions can be added to the product, by choosing it in the optional modules section including mic array/speaker, camera, LoRaWAN, 5G/4G, PoE. All components and ports are surface-mounted on two sides, making the resulting assembly slim and good for surface-mount applications.

reTerminal is expected to be available for pre-order in late April.
