Colibri

Colibri is a low-cost automation system, primarily intended for building automation, home automation, energy supervision, agriculture supervision and similar systems. Main features beside costs are;

• Flexible I/O system, via Expansion Cards in M.2 Key E sockets.
• Power supply of 7-36 Volt, either AC or DC (some expansion cards won't work with DC supply)
• Colibri-1 using LoraWAN for communications.
• Colibri-2 is a full-fledged Raspberry Pi, built with Compute Module 4 (CM4)

Form Factor

Colibri expansion boards are 22x42mm and has an edge connector called M.2 Key E. Many of the pins are following the Key E standard, but Colibri boards have additional requirements, which is not available in the official standard.

• • WARNING!!! DO NOT PLUG COLIBRI EXPANSION BOARDS INTO OTHER EQUIPMENT, NOR ANY M.2 BOARDS INTO THE COLIBRI SYSTEM THAT WERE NOT SPECIFICALLY MADE FOR COLIBRI.**
