description:
The PCF8591 is a monolithically built-in, individually powered, low energy, 8-bit CMOS information acquisition gadget. Voltage vary: 2.5V-6V.The PCF8591 has 4 analog inputs, one analog output, and one serial I2C bus interface. The three deal with pins A0, A1 and A2 of the PCF8591 can be utilized for {hardware} deal with programming, permitting entry to eight PCF8591 gadgets on the identical I2C bus with out further {hardware}. The deal with, management, and information indicators enter and output on the PCF8591 gadget are serially transmitted over a two-wire bidirectional I2C bus.

The left and proper facet of the module, respectively, outdoors the growth of 2-pin connector, respectively, as follows:
Left AOUT chip DA output interface
AINO chip analog enter interface 0
AIN1 chip analog enter interface 1
AIN2 chip analog enter interface 2
AIN3 chip analog enter interface 3

SCL IIC clock interface on the precise then single-chip IO port
SDA IIC digital interface related MCU IO port
GND module to floor
VCC energy interface exterior 3.3v-5v

Module a complete of three pink short-circuit cap, respectively, as follows:
P4 related to P4 short-circuit cap, choose the thermistor entry circuit
P5 related to P5 short-circuit cap, choose the photosensitive resistor entry circuit
P6 related to P6 short-circuit cap, choose 0-5V adjustable voltage entry circuit

We extremely respect all prospects opinions to enhance the promoting, additionally if something you unhappy, please contact us for possible greatest answer.

Package deal Contains: 3Pcs

The module chip adopts PCF8951 and helps exterior 4-channel voltage enter acquisition (voltage enter vary 0-5v)
Built-in photoresistor, can accumulate correct ambient gentle depth worth via AD, combine thermistor, can accumulate correct ambient temperature worth via AD, combine 1 channel 0-5V voltage enter acquisition (regulate the enter voltage via blue potentiometer)
With energy indicator (lights up after powering the module), with DA output indicator, when the output voltage of the module DA output reaches a sure worth, the DA output indicator on the board will likely be illuminated. The upper the voltage, the extra apparent the brightness of the indicator;
Commonplace double panel, board thickness 1.6mm, stunning structure, via holes round, gap diameter: 3mm, simple to repair
PCB measurement: 3.6cm*2.3cm
