Bluetooth Module Adapter
Bluetooth adapter module is a hardware tool suitable for configuring Bluetooth modules via PC using a HyperTerminal or any other configuration software. The Adapter is a dedicated USB‑to‑TTL interface for HC‑05/HC‑06 configuration. It accepts 5 V DC via a USB Type B socket and provides six female headers (ST, RX, TX, GND, VCC, KEY) plus an AT‑Mode switch for entering command mode. A green LED indicates power status, and an onboard 12 MHz crystal oscillator supplies the module clock. Designed on a compact 40 mm × 25 mm PCB, it streamlines AT‑command programming with any serial terminal.
Features
- USB Type B female input for 5 V DC power.
- Six TTL‑level female headers: ST, RX, TX, GND, VCC, KEY.
- AT‑Mode switch to toggle between data and command modes.
- Integrated green LED for clear power indication.
- Onboard 12 MHz crystal oscillator for module clock.
- Breadboard‑friendly 40 mm × 25 mm PCB layout.
