Furthermore, there is a [[Colibri Forth]] program located in the eeprom that contains the functionality of the module, executed in the MCU module. This allows for future expansion modules without requiring the upgrade of the MCU module.

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. Many types already developed.
  • Power supply of 9-36 Volt, either AC or DC (some expansion cards won't work with DC supply)
  • Each I/O slot can be powered-up/down individually from the MCU.
  • Each I/O slot is addressable individually.
  • Each expansion module has an EEPROM with program and calibration parameters for the MCU module to use.
  • Some expansion modules have on-board secondary processors for time-critical or other reasons, for instance pulse counting and PID regulator.


Carrier Boards

  • Colibri-3 using LoraWAN for communications and 2 I/O expansion slots.
  • Planned; Colibri-8 is like the Colibri-3, but with 7 I/O expansion slots.
  • Planned; Colibri-7pi is a full-fledged Raspberry Pi, built with Compute Module 4 (CM4) and 7 I/O expansion slots.

MCU Modules

There is a choice, and more will follow;

  • Colibri MCU1 - RAK3172 which has a STM32WLE5, 256kB Flash, 64kB RAM, on-chip LoRa and LoraWAN protocol available from GitHUb.
  • Colibri MCU2 - ESP32-S3-Mini-1-N4R2 which is intended for ESPhome applications. On-board PCB WiFi antenna.
  • Colibri MCU3 - ESP32-S3-Mini-1-N8 which is intended for ESPhome applications. IPEX/U.FL antenna connector.

Expansion Modules

The Colibri system is based around the M.2 connector and a non-standard bus for I2C and SPI communications. Each expansion board has a EEPROM memory available to identify which module is present in each expansion slot. Furthermore, there is a Colibri Forth program located in the eeprom that contains the functionality of the module, executed in the MCU module. This allows for future expansion modules without requiring the upgrade of the MCU module.

NOTE; Colibri Forth is only available/supported for the Colibri MCU1 at the moment. Porting to other MCUs might or might not happen in the future.

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. Do NOT plug any M.2 card into a Colibri system, unless that card/board is specifically made for Colibri.

License

All Schematics and PCB layout are licensed with the GPLv3, meaning that you are free to make your own designs or manufacture devices using these. We expect that if you derive new design, that you publish these, preferably on this website.

The software will also be published with GPLv3, when something is workable.
