Ymiko BT Serial Port Module RS232 Data Transmission Module Serial Port Module BC‑04 Wireless 5V Mini USB RS232 Serial Port Communication For /DOS/ Data Transmission

Feature: 1. Built‑in BT communication protocol no need to install additional drivers can be used in systems and non‑graphical operating systems such as DOS and . 2. Adopts CSR BT chip that supports BT 2.1 standard. Enhanced BER error rate performance and automatic frequency hopping technology can ensure efficient safe stable and interference‑free communication. 3. Can connect and communicate with BT‑enabled laptops desktop computers equipped with BT adapters handheld BT PDAs BT 4. Transmitting power complies with BT Class2 standard built‑in high‑sensitivity printed circuit board antenna stable communication distance up to 15 meters and wireless data transmission through wall. 5. Need to supply power to the adapter through the Mini USB interface on the adapter equipped with a RESET button can delete the stored paired device information and re‑pair with the new device.
