Description

KAmodBT-HC05 is a configurable (by using AT commands) Bluetooth module. Module has integrated LEDs, which signal work mode and connection state with device. Thanks to the small sizes and embedded translator of levels on TxD / RxD lines, module can be used in a lot of development projects.

MODE and PAR LEDs

KAmodBT-HC05 module was equipped with LEDs to signalling work mode and connection state with device. By default module settings, green MODE led signals visibility mode (blinking 5 times per second), configuration mode (blinking every 2s) and active mode (double blink every 2s). PAR LED (red) is ON, when communication with device is active.

Work mode button

KAmodBT-HC05 module was equipped with button for changing work mode - short holding in power supply enabled moment (or by reset) allow to run configuration mode of module (with using AT commands). Parallel with button is connected also KEY line - setting on this line HIGH signal (maximum 3.6V) allow to control work mode from e.g. microcontroller level. This line is pulled down with resistor 10kΩ.
