Description
The reTerminal is a Raspberry Pi all-in-one board, powered by Raspberry Pi Compute Module 4(CM4) module, integrated with one IPS panel type multi-touch screen, carried with dual-band 2.4GHz/5GHz Wi-Fi & Bluetooth 5.0, pre-installed Raspberry Pi-based Linux system, provided storage 4 GB RAM and 32 GB eMMC. By designing in modularization, the board is equipped with multiple accessible components and high-speed connectors. It can be neatly inputted home assistance and individual AI development applications, also performing industrial-level functions suitable for being an industrial facility.
Design in Modularization
Being an IoT hardware partner since 2008, Seeed improves its ability of hardware integration and designs the reTerminal to be modular. Hence, the reTerminal includes one industrial high-speed expansion PCIe interface on the back, along with a Raspberry Pi compatible 40-Pin GPIO connector beside, extremely expanding its application fields. Since the official expansion board reTerminal E10-1 has been published, reTerminal now is carriable and can be utilised in more advanced scenarios.
Rich Interfaces & Components
This all-in-one board still comes with 2 USB 2.0 Type-A ports, one MIPI camera interface, 4 programmable buttons, one RJ45 Gigabit Ethernet connector, one micro-SD card slot and an additional micro-HDMI interface which supports 4K resolution with a frame rate of 60 fps. These can be programmed for your further usage.
Meanwhile, there are several components mounted on the board, including a light & proximity sensor, LIS3DHTR accelerometer, buzzer, and Real-Time Clock(RTC). The power indicator light as well as other system user lights on the board can be used by your definition.
Wild Application Areas
The reTerminal can be your personal useful development board since it is built around Raspberry Pi CM4 module, and it provides multiple function thanks to its unique modular design and rich interfaces. You will find it more interesting when you discover there are plenty of skillful IoT & AI projects published by Seeed and the community.

And yet what about Industrial Internet of Things(IIoT) applications? It can be even amazed that reTerminal has equipped a cryptographic co-processor. That is to say, the reTerminal assembles a stable Linux operating system, high-speed expansion connector, multiple types of universal I/O, and hardware security, all of which make it hardware-ready for industrial equipment monitor and control.
