I’m fairly new to the home assistant community but I am active in the general (mostly german) smart home community for a long time.
Just wanted to let you know, that I’ve built a CC2538 Module for the GPIO of the Raspberry Pi (CC-BY-SA) which should be usable with home assistant as it’s “simply” a CC2538 without the USB-Part and available on
I liked the idea of having an external Antenna for (e.g.) electric cabinet mounted Pi’s and having it attached directly to the “inside” of the case.
It can be flashed via the serial interface directly on the Pi as the Z-Stack 3.0.x MODKAM UART Firmware with SBL (Serial Bootloader) is used. There’s also a Cortex-M0-JTAG present on the 2x5 header.
If you are interestend in the development of the module, have a look over to the GitHub issues from zigbee2mqtt:
Beside the common CC2538 module not much is needed so one can built it for themselfes - intermediate to good soldering skills required. We also sell these ready built and preflashed at our webshop in Europe: https://shop.codm.de/automation/zigbee/29/zigbee-cc2538-raspberry-pi-modul
(Please let me know if the link is ok, as I’m affiliated with cod.m)
Would be nice to hear your feedback.
