BT5.0 and NFC for Bluetooth Sensors, IoT, Edge-devices
Built around NXP’s QN9090 Bluetooth chip set, the CBT250 combines an ARM® Cortex®-M4 microcontroller with a high-performance Bluetooth v5.0 radio to offer OEM developers the ultimate in design flexibility. With 640 kB of executable flash, and 152 kB RAM, the CBT250 can host the end-user application. An optional 1 MB of additional flash allows for OTA firmware support. Offering a wide variety of peripherals, the CBT250 can function as the core of a product design or interface to a host processor via a serial interface. The modules wireless performance was designed to provide long range Bluetooth communication. Additionally, the solution offers very low power consumption in sleep, Rx, and Tx modes. Integrated NFC tag functionality offers the easiest, and most secure, method for pairing Bluetooth devices. The module is well supported with an evaluation board that plugs into the NXP development kit. Numerous BLE GATT and Standard Service examples, custom profile (OTA firmware, wireless UART) examples, and source code is available for rapid development.
