The Thingy:91 X is an upgrade to the original Thingy:91 which enables new features like WiFi, additional sensors, upgraded memory partitions, and new connectors to make extensibility a breeze. Best of all, it already works on Golioth!
Golioth already works on the nRF9151 SIP and associated Dev Kit from Nordic Semiconductor. Utilize the Golioth Firmware SDK with nRF Connect SDK to connect your cellular device to an advanced IoT cloud immediately.
