Bluno Bee - Turn Arduino to a Bluetooth 4.0 (BLE) Ready Board

SKU: TEL0073

The Bluno Bee is a versatile Bluetooth module equipped with the TI CC2540 chip, operating at a frequency of 2.4GHz with a maximum transfer rate of ≤1Mbps. Designed for low power consumption, it averages 10.6mA while operating and 8.7mA in ready mode, making it ideal for energy-efficient applications. With its GFSK modulation and Bluetooth low power V4.0 compatibility, the module ensures robust connectivity, boasting a sensitivity of -93dB. It requires an input voltage of +3.3 DC and can function within a wide operating temperature range of -40 ℃ to +85 ℃. The Bluno Bee offers a transmission distance of 15~20m indoors, extending up to 30m in open spaces, and measures a compact 32mm by 22mm, making it suitable for various compact projects. This article provides an in-depth look at the Bluno Bee's specifications and pinout, offering valuable insights for users seeking efficient and reliable Bluetooth solutions.
