CJMCU-ADS1115 16Bit ADC Development Board Module

Qualité excellente, semble robuste, conforme à la description

parfait

Great and easy to use 4 channel Analog to Digital Convertor. Very good precision with 16 bit. As an other reviewer said, you can't have enough of them.

This ADC has good resolution and for now it's working properly. I checked the documentation that some other reviewers proposed; thank you all for that. I am also considering buying 24-bit version.

Everything as expected, recommended.

It took some time to make it work. This is things all you need : https://learn.adafruit.com/adafruit-4-channel-adc-breakouts I2C adressing is a bit tricky pay attention to wiring and code compatibility. Also keep wires short and use shielded case for your project if it is possible.

I had to remove some of the pull up resistors on my boards as I am using 3 in a row Leaving the resistors would overload the I2C interface, something to remember when using multiple I2C modules on the same interface I also had to set the address as described in the IC documentation and now I have 3 of these devices connected together to read a string of 9 gas sensors The additional 3 lines were connected via resistor divider to the power supplies 1 to 3v3 using 2 10 k resistors as divider, 1 to the 5 v supply for the sensors, also via 10 resistor divider and 1 to the unregulated feed from the PSU but this is 90k & 10 k resistor divider, giving a reading of 1/10 the PSU voltage which can be between 7 and 30 volts in this case These are excellent little devices

I tried both of two modules with Arduino Nano mc and "Adafruit_ADS1015" ( https://github.com/adafruit/Adafruit_ADS1X15 ). The read values are correct, but the channel selection values (0 - 4) do not match the inputs (A0 - > 1, A1 -> 2, A2 -> 3, A3 -> 0). So, I can correct it in my own software, it is not fatal problem.

Easy to integrate in an Arduino design Good library available: https://github.com/adafruit/Adafruit_ADS1X15 Documentation available: https://www.adafruit.com/datasheets/ads1115.pdf

Good ADC. I use it to read strain gages, and it work as supposed. The sample rate, 16 bit and low noise makes it usable for professional applications. Great value for the buck!
