reTerminal - RPi CM4 4G RAM 32GB and 5-Inch Cap Multi-Touch Screen

The reTerminal is a Human-Machine Interface facility, designed in modularization, offering multiple interfaces and components. It is your hand-size, powerful, Raspberry Pi-based all-in-one board, assisting you to develop individual IoT & AI projects and being ready to materialize industrial-level monitor and control functions.

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 4GB/8GB RAM and 32GB 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.

Check out the review from ETA Prime on reTerminal:

Design in Modularization

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. Plus, this reTerminal now is carriable and can be utilized 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 that 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 the Raspberry Pi CM4 module, and it provides multiple functions 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.
