The AMS1117 module (5V) is a voltage regulator board designed to step down and stabilize voltage levels for powering low-voltage circuits. This module is based on the AMS1117 linear voltage regulator, which is widely used due to its simplicity, reliability, and efficiency in providing regulated output voltage.

The primary function of the AMS1117 module is to convert higher input voltages, typically between 6V to 12V, to a stable 5V output. It is particularly useful in applications where a precise 5V supply is required to power microcontrollers, sensors, and other electronic components. The module ensures that connected devices receive a steady voltage even if the input voltage fluctuates within its supported range.

Key Features:

1. Low Dropout Voltage: The AMS1117 regulator features a low dropout voltage, usually around 1.1V at full load, which means it can maintain a 5V output as long as the input voltage is at least 6V.

2. High Output Accuracy: The module provides a well-regulated 5V output with minimal variations, typically with an accuracy of ±1%.

Product Details:

This particular module is suitable for tutorial use and perhaps for some hobbyists. Its drawback is that its I2C address is hard-wired to all zeros. (Note that I2C is a very effective 2-wire communications standard that is used by many small semiconductor devices such as microcontrollers and sensor peripherals.) If the address lines could be jumpered high or low, then several identical modules could be placed on the same I2C lines. I would therefore recommend the alternative module named the Mini PCF8591 AD DA Shell Module because it has that capability. It is also at least three times the price.

The IC permits only 8 bit data allowing only 256 steps in the analog output value or the digital output value. This is likely borderline for hobbyists who may want to build instrumentation or test equipment.

My tests show another frustration: A lower than expected analog output voltage. For a 4.88 volt supply the output is only 4.17 volts (85%) at maximum value setting. Since the maximum supply voltage is 8 volts, increasing the supply to 6 volts may get a 5 volt result. I did not remove the green LED and related resistor to see if the problem was simply an excess current drain from the ICs AOUT.

Reference: PCF8591 8-bit A/D and D/A converter Product Specification, 2003-01-27, Philips Semiconductor.

The module is composed of:

• A PCF8591 IC at U1.
• A thermistor that measures temperature at R6.
• A photo-voltaic cell. This is a light sensitive resistor at R7.

• Two LEDs: a red one that is on when the device has power; and a green one that increases brightness as the output voltage increases.
• Three red jumpers that apply the voltage sources  photo-voltaic cell, thermistor, and potentiometer, and to analog input channels AIN0, AIN1, and AIN3 respectively.
• Connector pins for I2C (SDA and SCL), Vcc, and ground.
• Connector pins for the Analog output AOUT, and pins for each of the three analog input channels.
• A 4-wire ribbon cable is included with sockets suitable for the connector pins.
