HC-05 to Serial Module HC 05 Serial Module Embedded Serial Communication Module

HC-05 to Serial Module HC 05 Serial Module Embedded Serial Communication Module Kuvaus

The HC-05 is a serial module capable of operating in either master or slave mode; the mode can be switched via commands, and it supports a comprehensive set of commands. Power supply voltage: 3.3V. Current draw is approximately 2-8mA when unpaired and about 20mA when paired. Strictly avoid reverse polarity when connecting power!
Interface logic level: 3.3V. Can connect directly to various microcontrollers (51, AVR, , ARM, MSP430, etc.). Direct connection to 5V microcontrollers is also supported; no MAX232 is required, nor should a MAX232 be used.
The LED pin indicates the connection status: a pulsed output signifies no connection, while a high output indicates that is connected and the port is open.
