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.
