There are limitless possibilities with the reTerminal. It can be placed at the heart of an IoT/Edge system where you could connect a number of sensors to the reTerminal via different wireless protocols such as LoRa, Zigbee, Wi-Fi, Bluetooth, Sub-1G, and the reTerminal connected to the cloud via Ethernet, Wi-Fi, 5G/ 4G or connected to an edge server to store and process the data. 

Modular Design for Expanded Function

As you can see, reTerminal has a modular design where you can expand this system by connecting different modules. You can connect it via industrial high-speed connector on the back or the 40-Pin GPIO connectors on the side, to ebale enable even more applications. Meanwhile, you can easily plug modules such as mic array & speaker, camera, industrial I/O, LoRaWAN, 5G/4G, and PoE to realize your ideas! It will be supported by an active community as well!

reTerminal has a high-speed expansion interface with a PCIe 1-lane Host, Gen 2 (5Gbps), USB 2.0 port, 28 GPIOs, and PoE. You can use this interface for industrial and more advanced scenarios! The official industrial high-speed expansion board, reTerminal E10-1 is coming out, which is fully compatible with the reTerminal where they can be simply connected through the industrial high-speed signal connector, you can refer to here for further information.

reTerminal is packed with rich interfaces on the side of the device while keeping the design to a minimum. It has a USB Type-C port for power input, a Gigabit Ethernet port for faster and reliable network access, a micro-HDMI interface that supports video output at 4K resolution with a frame rate of 60fps, and also has 2 USB Type-A ports.

reTerminal also features a 5-Inch IPS capacitive multi-touch screen with a resolution of 1280 x 720 and a pixel density of 293 PPI, providing high definition and rich colors. This resolution is 1.6 times higher than the most common resolution for 5-inch displays, which is 800 x 480. Also, comparing to TN displays, the IPS display on the reTerminal offers better viewing angles as well!

reTerminal has security features such as a cryptographic co-processor with secure hardware-based key storage. It also has protected storage for up to 16 keys, certificates, or data. It provides hardware support for symmetric sign, verify, key agreement – ECDSA. It has hardware support for symmetric algorithms, networking key management and secure boot.

  1. Product Quality
    from order view
    Good documentation and quality, hardware is very well built and well presented
  2. Product Quality
    from order view
    Seeedstudio manufactured-As expected from the documentation & advertisement of course. Good for practical use with CM4.
  3. Product Quality
    from product detail summary
    Product arrived flawlessly, well packaged, but without any documentation for a quick start or other features. I think that a booklet for a quick start (by default) would have facilitated the first grip, and would have given a 5 star to the documentation (you have to go necessarily on the internet). But considering the quality of the product....!
