Sub-GHz radio at 868 MHz via a TI CC1101 (FSK and OOK), coupled to a freely programmable ESP32-C6 – the successor to the CUL family, with USB-C and an RP-SMA antenna socket.
ESP32-C6: Wi-Fi 6 (802.11ax, 2.4 GHz), Bluetooth 5 LE and an IEEE 802.15.4 radio for Thread and Zigbee.
Frequency: the CUL32 is built for 868 MHz only; there is no 433 MHz version.
Free firmware, flashed in the browser at install.busware.de/CUL/: culfw32, FHEM/CUL compatible.
Ethernet extension (option): the W5500 extension connects the stick by cable instead of Wi-Fi; with PoE it takes network and power over that one cable. Both variants are selected as an option above – they need the larger “plastic for Ethernet” enclosure.
Photos: the pictures show the stick with an optional antenna. Antenna, enclosure and extension are selected and priced as options above; the base price covers the stick without them.
Note: We supply OEM hardware without firmware only – not a finished end product. Flashing the firmware and commissioning are the buyer's own responsibility.
