Seeed Studio provides reliable electronic products and services to developers to help them build new products and applications. Now Seeed Studio has released its first Raspberry Pi-powered industrial human-machine interface (HMI) device. Which is named as reTerminal, designed and certified for IoT developers to build industrial applications based around the Raspberry Pi Compute Module 4. It works efficiently with cloud systems to unlock endless scenarios at the edge.
This new Seeed Studio HMI device, reTerminal comes with a 5inch touchscreen and plenty of expansion possibilities. And it features a high-speed expansion interface and rich I/O for more expandability. Comes with security features such as a cryptographic coprocessor that supports secure hardware-based key storage. In addition to this, it has built-in modules like an accelerometer, light sensor, and an RTC (Real Time Clock).
HMI, Human Machine Interface known as the user interface, the dashboard that connects a person to a system in industries. Generally, HMI’s are stand-alone terminals as a part of a machine. With modern tech developments, future HMI’s can offer better tools for developers to apply AI and machine learning algorithms based on the IoT sensors data and the ongoing behavior of the operator.
This Seeed Studio HMI device reTerminal will be available for pre-order in late April. It comes with an enclosed inside a robust case, in a compact form factor with the dimensions of 1409521mm. Also, it comes with a Raspberry Pi Compute Module 4 with 4GB RAM and 32GB eMMC.
Here are the details of the Seeed Studio HMI device, reTerminal
This new Seeed Studio HMI device, reTerminal comes with a Gigabit Ethernet Port for faster network connections. Its 40-pin Raspberry Pi compatible header on the reTerminal enables it for a wide range of IoT applications. And you get a 5-inch LCD touch screen with 1280 x 720 resolution. Which is better than the 800 x 480 resolutions that you generally find on other screens. Also, you get four user buttons that you can program as you need to quickly access common tasks.
On the left side of the device, you get two USB 2.0 ports and Gigabit Ethernet micro HDMI output. Plus you get a USB C power input to charge the device, you require 5V 4A to power the unit. On the other side, you get a breakout board for the Raspberry Pi GPIO. Through which you can add one of the many Raspberry Pi add-on boards with a breakout board.
Coming to the back, the Seeed Studio HMI device features a finned radiator. Which can be used to keep the Compute Module 4’s 1.5 GHz quad-core Cortex-A72 CPU cool to work efficiently. Also, this HMI device comes with a MIPI camera interface, that enables usage of the official Raspberry Pi camera and the HQ camera.
Based on the press release, reTerminal mainly focused on machine learning applications such as Edge Impulse, PyTorch, and TensorFlow. In addition to this, you get an industrial high-speed interface that provides a PCIe 1 lane host. Along with an additional USB 2.0 port and Power over Ethernet.
Wide range of possibilities with the Seeed Studio HMI device
The Seeed Studio HMI device, reTerminal has several application possibilities. Such as it can be placed at the heart of an IoT/Edge system. From there you can connect and access a number of sensors to the reTerminal via different wireless protocols. Such as LoRa, Zigbee, Wi-Fi, Bluetooth, and Sub-1G. Also, you can connect the reTerminal to the cloud via Ethernet, Wi-Fi, 5G/4G, and process the data.
In addition to this, its modular design expands the system by connecting different modules to the reTerminal via the 40 pin GPIO connectors. Which enables even more application accessibility. And you can easily plug modules like mic array and speaker, camera, industrial I/O, and PoE. Also, there is an active community to assist and support you whenever you need help.
Apart from this, the Seeed Studio HMI device brings security features such as a cryptographic coprocessor with secure hardware-based key storage. It can protect storage for up to 16 keys, certificates, or data. Also, you get hardware support for asymmetric signs, verification, and key agreement.
If you observe carefully you will find that a series of M4 screw mounts are made at various points around the device. To secure the reTerminal from other external modular accessories. The industrial GPIO breakout from the supplied images and a unit that lets you connect it to the industrial high-speed breakout connectors. And Seed Studio HMI device has a standard camera mount at the bottom of the unit. This enables reTerminal to keep itself steady using many different camera accessories.
Other details
A series of sensors, placed inside of the reTerminal. It has a mic array used with machine learning for voice recognition projects. An accelerometer used for display rotation, data collection, and gesture input. Also, the onboard real-time clock allows you to keep your Compute Module 4’s clock in time. This is especially useful for projects, where connectivity to the NTP server is problematic.
However, With the new HMI device, reTerminal Seeed Studio expects to provide a solid base for UX and machine learning experts. To enhance the traditional machines with the latest productivity. With the help of growing hardware extensions and software partnerships, the company is expecting to create an open collaborative ecosystem to redefine terminals.
Conclusion
The Seeed Studio has released the new Human Machine Interface device,reTerminal. It is fully featured, designed, and certified for IoT developers to design industrial applications that are based on the Raspberry Pi Compute Module 4. It has a 5inch touch screen and comes with plenty of options for expansion. This new Seed Studio HMI device, reTerminal will be available for $195
