CoMatrix Architecture and Testbed Overview

CoMatrix Architecture & Testbed

CoMatrix Gateway:
- Raspberry Pi 3B(+)
  - https://www.raspberrypi.org/products/raspberry-pi-3-model-b-plus/
- OpenLabs Raspberry Pi 802.15.4 radio module
  - https://openlabs.co/store/Raspberry-Pi-802.15.4-radio
  - CAUTION: In our tests the module was not able to successfully communicate when used with a Raspberry Pi 4 and current Raspbian/Raspberry Pi OS (i.e. Linux raspberrypi 5.10.17-v7+)! We recommend to use a Raspberry Pi 3B(+).
CoMatrix Client:
- Atmel SAM R21 Xplained Pro Evaluation Kit (SAMR21-xpro) microcontroller
  - https://www.microchip.com/developmenttools/ProductDetails/ATSAMR21-XPRO
- Temperature sensor “DS18S20+”

Matrix Synapse homeserver:
- Raspberry Pi 4
A laptop or mobile phone (running Matrix Element client)
- OPTIONAL: Nordic nRF52840 Dongle for monitoring/sniffing of 802.15.4 network traffic
