The BentoIO CMX1 is a compact, low-profile Raspberry Pi CM5 carrier board, developed by Terioto in Germany. With an 85 x 85 mm footprint and a height of just 11 mm, it’s designed for space-constrained applications like embedded systems, industrial control, and compact edge devices.
After the official launch of the Raspberry Pi CM5 module and its carrier board, we’ve seen boards like Waveshare CM5-NANO-B and Orange Pi CM5 “Tablet” Base Board get released. There is no doubt that they are compact, but they are not as slim as this board. While it’s slim, that doesn’t mean it lacks I/Os; it includes a 40-pin Raspberry Pi-compatible GPIO header, two USB 3.0 ports, two internal USB 2.0 headers, a MIPI DSI connector and an optional HDMI port for video output, optional gigabit Ethernet, a PCIe M.2 M-Key for expansion, and it uses a USB-C for power. Other features include an RTC battery connector, 4-pin fan header, power button, flash mode switch, and a microSD slot for CM5 Lite (non-eMMC) modules. The board follows standard Raspberry Pi mounting dimensions for easy integration and setup.

While going through the specifications, it’s clear that there are many features that this low-profile Raspberry Pi CM5 carrier board is missing. There’s no dedicated interface for a camera module, and no separate M.2 slot for Wi-Fi, though you can always use a USB Wi-Fi dongle if needed. Additionally, there is no 3.5mm audio jack for analog audio output. Additionally, you have to purchase the BentoIO CMX1 Expansion Board for LAN / HDMI separately if you need those features.
There is no specific information about software support, but it should support 64-bit Raspberry Pi OS (Bookworm) with Linux kernel 6.x, and other compatible operating systems. Peripherals such as M.2, USB, and SD card should get recognized natively, but others may require additional drivers. More information, including a user manual, can be found on the documentation.
The BentoIO CMX1 carrier board is priced at $119.00 on Tindie, or alternatively, the board and accessories like the HDMI/LAN expansion board and the low-profile heatsink can be purchased on Terioto’s website.
