Notecard’s JSON-over-serial API (UART, I2C, SPI) allows any host microcontroller to send data to Blues’ Notehub cloud with a single JSON command, abstracting cellular complexity entirely. The included global SIM roams across 130+ countries on LTE-M, NB-IoT, and 2G fallback, providing connectivity without carrier negotiations for product builders. 500 MB of data included at purchase means a Notecard deployed for asset tracking or environmental monitoring can operate for years without incremental data fees. GPS enables location-stamped asset tracking without additional hardware. Notehub.io routes data to AWS, Azure, Google Cloud, ThingSpeak, and custom webhooks with no coding on the cloud side.
