4 管脚接口

Pin Interface

注意:模块只能 3.3V 供电,5V 供电会烧毁芯片,切记切记!

Attention: The model only apply to 3.3V power supply

正面:

Frontside:

 GPIO12 GPIO13 GPIO14 GPIO4 GPIO5 GPIO15


背面:

Backside:

 GPIO16 GPIO0 GND TX RX VCC


默认烧写的固件为 5 路继电器控制固件,使用的 GPIO 资源为: The default firmware is 5 channel relay control firmware, GPIO source:

1. GPIO13(D4) control the 1st relay
2. GPIO12(D5) control the 2nd relay (pull up)
3. GPIO14(D6) control the 3rd relay
4. GPIO16(D7) control the 4th relay
5. GPIO4 (D8) control the 5th relay


6 路继电器控制固件,第 6 路为: GPIO5 (D9) control the 6th relay

6 channel relay control firmware, the 6th channel is: GPIO5 (D9) control the 6th relay


应用如需外接 I2C 口的传感器、OLED 屏等,可将 GPIO4 (D8) 和 GPIO5 (D9) 作为 I2C 之 SCL 和 SDA,参考示例:

If need to connect sensor with I2C interface, OLED screen etc...GPIO4(D8) and GPIO5(D9) can work as SCL & SDA of I2C, for example:


这样即便 GPIO4 和 GPIO5 用作 I2C,依然有 GPIO12, GPIO13, GPIO14, GPIO15, GPIO16, GPIO0 用作继电器控制

Although GPIO4 and GPIO5 act as I2C, GPIO12, GPIO13, GPIO14, GPIO15, GPIO16, GPIO0 still work as relay controller

6 Driving Relay

The model is 3.3V electrical level, a simple peripheral circuit is necessary to drive 5V relay:

Relay-driver.jpg


Relay recommend HKE HRS3FNH

SI2302 MOSFET pipe can be exchanged by DTC143ECA (remove R1)

This circuit is stable & reliable that has been tested through 1200W inductive load & capacitive load, and mass for mass production。


Multi channel relay control can copy the unit circuit.



7 Push Button & LED

Default Firmware Support:

  • GPIO0 can pick up a button then press to connect ground. Firmware supportable. Short press to reverse all relays situation, long touch to restore factory settings
  • RX receive a blue LED into the ground. Firmware supportable can be used to indicate WiFi situation

8 Power Supply

The supply voltage of model is 3.3V, required current is 200mA, peak current for special case is up to 1A

Rated current of the power supply must be more than 600mA. Insufficient current will cause chip unstable, most oftenly reboot with no reason

Recommend adding 220uF / 470uF capacitor to power output side in response to 1A peak current of the chip

DC-DC chip, recommend AP2112 (5V switch 3.3V,compact size) / AMS1117-3.3 (12V-5V switch 3.3V,high current) / WL2803G

9 Update Firmware

Default firmware that the model upload is WeChat control 5 relay, 6 relay firmware can be write by your own

Bootloader built in, the firmware can be uploaded through the serial port directly

GPIO0 start up is normal; Pull down and then power up the module will automatically enter upgrade mode

9.1 Tools

The programming Interface were in the back of module. Use a 5-pin probe on Dupont line, connected to the USB switch TTL Panel, firmware can be upgrade then.

One USB switch serial port board, we used a FT232RL breakout board / Noduino Falcon board

Ft232.jpg


Wiring as below:

  • USB_GND ------> NODE_GPIO0
  • USB_GND -----> NODE_GND
  • USB_RXD -----> NODE_TX
  • USB_TXD -----> NODE_RX


Last but not least, USB_VCC3.3 -----> NODE_VCC power on, then enter upgrade mode



9.2 Prepare Firmware

Fetch the noduino-sdk

$ git clone --recursive git://github.com/icamgo/noduino-sdk.git noduino-sdk


Generate toolchain (you need Python 2.7)

$ cd noduino-sdk/toolchain
$ ./gen.py


Compile:

$ cd ../sketch/ctrl6relay
$ make


Noduino SDK usage under different platform please refer to:



9.3 Firmware upload

In sketch/ctrl5relay directory, 'make flash' directly:

$ make produce

Firmware will be uploaded. Number of your serial port might be different in different platform, please confirm the device. For instance, FT232RL board may be identified as COM3 in Windows(check in device manager),then:

$ make produce ESPPORT=COM3



10 FAQ

10.1 RF performance

Appearance test, assure network connection and control normal operation in home environment with WiFi through a wall

If network connection failed many times or drop the line occurs often, please use the oscilloscope to confirm the power supply ripple

In general, send 11N MCS7 packet, power supply ripple must be <80mV. Send 11B packet then power supply ripple must be <120mV
