M5Stack CM4Stack – A tiny Raspberry Pi CM4 Linux laptop with an built-in 2-inch show
M5Stack CM4Stack is a tiny Arm Linux mini PC based mostly on Raspberry Pi CM4 that measures 59 x 44 x 46mm and integrates a 2-inch touchscreen show for info and management, in addition to the same old ports you’d anticipate from a mini PC akin to HDMI, USB 3.2 ports, Gigabit Ethernet, and so forth.
We’ve beforehand written about M5Stack Core and Atom controllers based mostly on ESP32 microcontrollers, an non-compulsory 2.0-inch show, and some GPIOs. The corporate has now determined to supply an identical resolution with a bounce in efficiency and interfaces with the CM4Stack growth equipment.
CM4Stack specs:

The equipment comes with a 12V/3A energy adapter, an Allen/Hex key, a base snap, a screw holder, and an instruction guide. The event equipment/mini PC runs Raspberry Pi OS, and the corporate supplies a Qt demo with a clock to point out tips on how to use the built-in show. There’s additionally additional {hardware} element on the documentation web site.
Typical functions embrace industrial automation, Good Residence, Web of Issues (IoT), and schooling and growth. The CM4Stack is obtainable now for $199 with the Raspberry Pi CM4, however shares are restricted as just one piece is in inventory on the time of writing.
Jean-Luc began CNX Software program in 2010 as a part-time endeavor, earlier than quitting his job as a software program engineering supervisor, and beginning to write every day information, and evaluations full time later in 2011.
