Add Bluetooth 4.0 to your PC, Mac directly with this USB BLE-Link. It uses the USB package which is compact and compatible with v2.1 and earlier, and also supports the latest v4.0/Bluetooth Low Energy. Now you could use this adapter to receive/transmit data. With two USB-BLE Link users can do point-to-point wireless transparent transmission, master-slave machine setting, and wireless programming. It can also work as a PC BLE wireless programming adapter. Compatible all DFRobot BLE series modules: i.e. Bluno - An Arduino Bluetooth 4.0 (BLE) Board, Romeo BLE (Arduino Robot Control Board with Bluetooth 4.0), etc Bluetooth 2.0 Module V3 For Arduino Bluetooth 2.0 Bee Module For Arduino Bluno Link - A USB Bluetooth 4.0 (BLE) Dongle Bluetooth Adapter Mini SKU TEL0073 TEL0026 TEL0023 TEL0087 TEL0002 BLE Chip TI CC2540 CSR BC417143 CSR BC417143 TI CC2540 — Frequency 2.4GHz 2.4 ~ 2.48GHz unlicensed ISM band 2.4 ~ 2.48GHz unlicensed ISM band 2.4GHz 2.4 ~ 2.48GHz FHSS Transfer rate 1Mbps GFSK Asynchronous: 2.1Mbps (Max) / 160 kbps; Synchronous: 1Mbps/1Mbps Asynchronous: 2.1Mbps (Max) / 160 kbps; Synchronous: 1Mbps/1Mbps 1Mbps GFSK 3Mbps BLE protocol V4.0 V2.0 + EDR V2.0 + EDR V4.0 V2.0 Modulation GFSK GFSK GFSK GFSK FHSS Power consumption 10.6mA average, ready mode: 8.7mA — — 10.6mA average, ready mode: 8.7mA — Sensitivity -93dBm ≤-84dBm ≤-84dBm -93dBm ≤-84dBm Working Voltage 3.3V +3.5 V ~ +8 V DC and 3.3V DC/50mA 3.3V 3.3V — Operating temperature -40 ℃ ~ +85 ℃ -20 ℃ ~ +55 ℃ -20 ℃ ~ +55 ℃ -10 ℃ ~ +85 ℃ -20℃ ~ +55℃ Transmission distance 30m 20 ~ 30m 20 ~ 30m 10 ~ 20m <10m Dimension 32*22mm 40*20*13mm 32*24*9mm 32mm * 16mm 20*16*8mm Weight (g) 10 10 12 10 10 AT command to debug the BLE √ √ √ √ — master-salve machine switch √ √ √ √ — Transparent transmission √ √ √ √ — Wireless programming √ (Available for Bluno series) — — √ — iBeacons √ — — — — BLE HID √ √ √ √ √ Mobile App Control √ √ √ — — Key Features support Android and IOS applications,open source code,suitable for secondary development by the user Compatible with APC220 communication interface, can be directly used in I/O Expansion Shield, Romeo, XBoard and etc,.
