== Pin Interface == <font color=red><b>Attention: The model only apply to 3.3V power supply !</b></font> Frontside: GPIO12 GPIO13 GPIO14 GPIO4 GPIO5 GPIO15 Backside: GPIO16 GPIO0 GND TX RX VCC The default firmware is 5 channel relay control firmware, used GPIO resource: <pre> 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 </pre> 6 channel relay control firmware, the 6th channel is: GPIO5 (D9) control the 6th relay 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: * [[Noduino SHT2x]] SHT2X Digital Humidity & Temperature Sensor * [[Noduino TSL2561]] TSL2561 Digital Luminosity/Lux/Light Sensor * [[Noduino BMP180]] BMP180 Barometric Pressure/Altitude Sensor * [[Noduino BMP085]] BMP085 Barometric Pressure/Temperature/Altitude Sensor * [[Noduino BH1750]] BH1750 Digital Light Sensor * [[Noduino PCF8563]] PCF8563 I2C RTC Chip * [[Noduino OLED]] SSD1306 I2C OLED Screen support * [[Noduino I2C Scan]] Scan all the I2C devices Although GPIO4 (as SDA) and GPIO5 (as SCL) act as I2C, GPIO12, GPIO13, GPIO14, GPIO15, GPIO16, GPIO0 still work as relay controller <br><br>
