The 453-00039R is a high-performance Bluetooth Low Energy (BLE) module from the BL653 series by Laird Connectivity (Ezurio). Built on the Nordic nRF52833 chipset, it provides ultra-low power consumption and long-range connectivity using Bluetooth 5.1 features like Coded PHY and Direction Finding (AoA/AoD). The module also supports 802.15.4 (Thread/Zigbee) and NFC tag functionality. It features an integrated chip antenna and is designed for industrial applications requiring an extended temperature range. Programming options include smartBASIC, AT commands, Nordic SDK, and Zephyr RTOS.
