3 GPI01 internal access module to accept control foot
4 GPIO2 directly connected to the chip GIIO2 pin
5 VCC positive supply 3.3V
6 SDO 0-VDD V digital output provides a serial readback function of the internal control register
7 SDI serial data input. 0-VDD V digital input, this pin for 4-wire serial data clock function
8 SCLK serial clock input. 0-VDDV last month set of inputs. This pin provides a 4-wire serial data clock function
9 NSEL serial interface select input pin,0-VDDV digital input. This pin to 4-wire serial data bus select / enable
function,
this signal is also used, said the burst read / write mode.
10 NIRQ interrupt output pin
11 SDN Close the input pin. Input 0-VDDV digital. SDN = 0 in shutdown mode, so mode
12 GND access power ground
13 ANT 50 ohm coaxial antenna
14. Supply voltage: 3.2V~5.5V. (If the module you want to work long hours in the
emission state,
it is recommended that when the supply voltage exceeds 4.5V threaded a
1N4007 diode
to prevent module built-in LDO heated)
Default address range (open field test): About 600m (maximum communication
distance
adjustable reach 1000m, the baud rate is 5000bps)
Default idle current: 16MA (In different working modes operating current is
different)
Module dimensions: 27.8 x 14.4 x 4mm
Operating frequency range: 433.4-473.0MHz, up to 100 channels of
communication
The maximum transmit power: 100mW (settable)
Module support software upgrade
Default factory settings: Mode FU3, baud rate is 9600bps, communication
channels CH001 (433.4M)
15. Example:
Set module to channel 21, please send module command "AT + C021", the module returns "OK + C021".
After exiting the command mode, the module in the first 21 channels, operating frequency is 441.4 MHz.
Note: Because the wireless receiver module sensitivity HC-12 is relatively high, the baud rate is greater
than when air 58000 bps, 5 must be shifted to the adjacent channel use. When the air baud rate is not
greater than 58000 bps, if the short distance (10 meters) communication, but also need to stagger five
adjacent channel use.
4. AT + FUx
Change the module serial pass-through mode, there FU1, FU2 and FU3 three modes. Module default
mode is FU3, two serial pass-through mode module must be set to the same communication.
See detailed above, "wireless serial pass-through" part.
Example: Send module commands "AT + FU1", the module returns "AT + OK".
5. AT + Px
16. 1. AT
Test instructions
Example: Send module commands "AT", the module returns "OK".
2. AT + Bxxxx
Change the serial port baud rate command. You can set the baud rate is
1200bps, 2400bps, 4800bps, 9600bps, 19200bps, 38400bps, 57600bps and
115200bps. The factory default is 9600bps.
Example: Set the module serial port baud rate is 19200bps, please send
module command "AT + B19200", the module returns
"OK + B19200".
3. AT + Cxxx
Change the wireless communication channel, selectable from 001 to 127
(more than 100 radio channels
after the communication distance not guaranteed). The default value is 001
radio channels, operating
frequency is 433.4MHz. Step channel is 400KHz, the operating frequency of
the channel 100
is 473.0 MHz.
20. The NodeMCU is an open source
firmware and development kit
based on ESP8266 that integates
GPIO, PWM, IIC, 1-Wire and ADC
all in one board. Power your
developement in the fastest way
combinating with NodeMCU
Firmware!
21. NodeMCU is the most popular development board for the hugely popular
WiFi IoT chip from Espressif, the ESP8266.
It uses the Lua scripting language to make it easy to run user programs
on the ESP8266 without any recompilation.
The board consists of an
1. ESP-12E module,
2. CP2102 (for usb to uart),
3. and USB connector for power.
All the pins of the ESP-12E are brought out on compact and narrow
board design to make it breadboard friendly.
You can use the nodemcu firmware, or the Arduino development
environment or build your own firmware using Espressif's SDK for the
ESP8266.
22. • Arduino-like hardware IO
• NodeJS style network API
• Lowest cost WIFI development tool
• Reprogramming possibility
• Multiple uses
• Use directly in your application
• One ADC input and 8 digital IOs
• 3.3V operation
• Compact size: 25.4mm x 50.8mm (2" x 1")
• Provision for external battery along with on/off switch
