Parts List

Host Controller & Radio

• A Raspberry PI is the intended target for the broker logic, and can optionally run front end logic like the rendered TUI and database. Tested on a few including rpi4 and rpi5

  • rpi4,
  • rpi5.

• Currently using the rpi5 with 8Gb RAM which works great. The pi must be set up to run the openthread stack & otbr-agent follow instructions here and configured as a host for running openthread in RCP mode.

• Pis dont have built-in support (yet?) so you will need an 802.15.4-capable radio (external dongle) configured to run as an RCP (radio co-processor) on the pi. Tested with the following RCP dongles

  • nRF (nRF52840)
  • silabs EFR32 (MG21)

• Others exist (for example the esp32h2 adn esp32c6 can both run RCP mode) anything that is 1.3 ceritifed should work. See the openthread list of supported platforms here.

ESP32 sensor nodes

• esp32-c6 with 4MB flash

• esp32-c6 with 8MB flash

• esp32-h2 with 4MB flash

• Other dev board options exist with these chips, for example if you want something with QWIIC (however the code in pmindp-esp32-thread is not compatible):

  • sparkfun thing plus with esp32c6 and
  • adafruit feather with esp32c6

Note: As of this writing I have only tested h2s with 4MB and c6s with 8MB flash

Sensors

Soil Sensors

• Seesaw Capacitive moisture sensor

Also will be testing / developing code for additional sensors eventually:

• Sunfounder capacitive moister sensor
• SparkFun soil moisture sensor

Other sensors

• Adafruit TSL2591 light sensor
• Adafruit BME680 humidity/gas/pressure sensor
