convertidor A/D ideal para trabajar con sensores analógicos en proyectos basados en el IDE de Arduino, pero que utilizan placas que tienen pocas entradas analógicas. Ejemplo: NodeMCU: solo cuenta con una entrada A/D; en un proyecto de riego, al conectar varios sensores de humedad del terreno es imposible hacerlo solo con NodeMCU, y las alternativas son: unir NodeMCU a un Arduino UNO (por I2C o puerto serie) y capturar datos con Arduino UNO, o usar este pequeño módulo, lo que me parece mucho más

Excellent! Totally compatible with the Arduino and STM32 Boards and WORKS PERFECT!!! Good accuracy in 16Bit resolution and fast communication with the controller board. Beware with the voltages especially when you connect with 3.3Vdc PSU Rails. I used with RPi3 and STM32s Blue Pills connected with I2C Level Adaptor 3.3v to 5V. Seller’s service was GREAT!!! Comes packaged in antistatic bag. TOTALLY RECOMMENDED!!!

It works and looks like good quality.

Top alles ok

Working as expected!

These are useful extenders for MCUs that have too few ADC ports. They are easy to use and give 15 bit resolution (16 in differential mode). They are good value and I'd recommend them. Details of the board and ADS1115 can be found at https://learn.adafruit.com/adafruit-4-channel-adc-breakouts/

Works great, wish I knew about these a while ago. Increases the ESP8266 for many other projects

The parcel arrived in less than 15 days. The module was in good condition and functional.

Works exactly like described. Very stable and seems to be as accurate as specified.

Handy little interface for sonoff basic hardware hacking...
