reTerminal DM-R100

Panel, VESA, and DIN Rail mounting options are offered, and we can find a fair amount of optional features in the specifications because Seeed Studio can customize the design upon request. On the software side, the new HMI controller runs Raspberry Pi OS or SenseCraft Sense OS with “a natively integrated Node-RED for flow-based editing and one-click deployment” compatible with all software that runs on the Raspberry Pi. More details to get started can be found in the wiki.
