6 Pin HC-05 Wireless Module Transceiver Module Serial RS232 Wifi Module
Specifications:
| Material | PC |
| Color | with the chassis HC-05 master and slave integrated |
| PCB size | 37.3mm (length) * 15.5mm (width) |
| Weight | 3.5g |
| Input voltage | 3.6V - 6V, prohibit more than 7V |
Description:
Power supply anti-reverse, then the module does not work
6 feet: EN / VCC / GND / RXD / TXD / STATE (Wireless status pin,
not connected to the output low, connected to the output high)
With the connection status indicator, LED flash means no Wireless
connection; LED slow flash to enter the AT command mode
On-board 3.3V regulator chip, input voltage DC 3.6V-6V; unpaired,
the current is about 30mA (due to LED flashing, the current is in a
state of change); matching success, the current is about 10mA
Interface level 3.3V, you can directly connect a variety of
single-chip (./51/AVR/PIC/ARM/MSP430, etc.), 5V microcontroller can
also be directly connected. Directly connected to the
microcontroller serial port, not through the MAX232 chip!
Effective transmission distance of 10 meters, more than 10 meters
is also possible, but do not guarantee the quality of the
connection
After successful pairing, can be used as a duplex serial port. No
need to understand any Wirelessprotocol, but only supports 8-bit
data bits, 1 stop bit, no parity communication format. This is also
commonly used in Z communication format, do not support other
formats!
Press the button to power the Wireless module can enter the AT
mode, set the parameters and query information
The host and slave modes can be switched via the AT command
The default baud rate is 9600 and the default pairing password is
1234. The default name is HC-05
With transparent heat shrink tubing protection
Second, the wiring method:
VCC: Connect the power supply positive
GND: Connect the power supply negative
RXD: the receiving end, the Wireless module receives the data sent
from other devices; normally send the TXD of the other device
TXD: the sender, the Wireless module to send data to other devices;
normal access to other devices receiving RXD
EN: Enabled, need to enter AT mode when connected to 3.3V
Weight: 4g
1 cm = 0.3937 "
Precautions:
1. Please allow 1-3cm differences due to manual measurement.
2. Clothing Asian size is usually 2 yards smaller than the US / EU
/ UK, please compare carefully before ordering.
12. The real color may be slightly different from the photo, due to
a variety of factors such as computer screen contrast or light.
