Want to control your devices via Bluetooth from your phone, or maybe from an Arduino, Iskra or Raspberry Pi? Why not try the Troyka Bluetooth HC-05 module? It supports both slave and master modes, available to both control and be controlled.

Create a network of Bluetooth-connected devices and control them with the HC-05 module. Manage sensor data, send commands, or even control robots without any additional software. Any Bluetooth module, such as HC-06, can act as a slave device.

The operating voltage of the HC-05 is 3.3 V. However, we have added a voltage regulator such that it works at 5V as well.

Connectivity

For an Arduino, the module works just like a serial interface:

  • RX pin connects to the target device's TX pin
  • TX pin connects to the RX pin of the target device
  • V connects to the power supply pin (3.3 — 5 V)
  • G connects to ground
  • Use contact K forces AT Command Setup Mode

Connect the module via 3-pin jumper cable. The 3-pin jumper cables needed for the connection are included in the kit.

There are several different ways to wire this module:

Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.

Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.

Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC.
