Dear sir,
i just bought EdgeBox-ESP-100 and have some test
i have problem with ADC input because document haven’t scale referent like resistance divider

Do you could work with the ADC? i have problems with that

Yeah it’s work
You can use this code

#include <Wire.h>
#include <Adafruit_ADS1X15.h>
Adafruit_ADS1115 ads;


// I2C PIN
#define I2C_SDA     20
#define I2C_SCL     19
#define Wakeup      9



 void ADS_init()
 {
  // ads.setGain(GAIN_TWOTHIRDS);  +/- 6.144V  1 bit = 0.1875mV (default)
   ads.setGain(GAIN_ONE);        //+/- 4.096V  1 bit = 0.125mV
  // ads.setGain(GAIN_TWO);        +/- 2.048V  1 bit = 0.0625mV
  // ads.setGain(GAIN_FOUR);       +/- 1.024V  1 bit = 0.03125mV
  // ads.setGain(GAIN_EIGHT);      +/- 0.512V  1 bit = 0.015625mV
  // ads.setGain(GAIN_SIXTEEN);    +/- 0.256V  1 bit = 0.0078125mV 
  ads.begin();
 } 
  

void setup() {
Serial.begin(115200);
delay(2000);
Serial.println("Module Initial");
Wire.begin(I2C_SDA, I2C_SCL,400000L);
 ADS_init();
}

void loop() {
   int adc0, adc1, adc2, adc3;
  // // 3.7 mA  = 1658
  // // 22.7 mA = 10060
  // // adc0 = ads.readADC_SingleEnded(0)*22.7f / 10052;
  // // adc1 = ads.readADC_SingleEnded(1)*22.7f / 10052;
  // // adc2 = ads.readADC_SingleEnded(2)*22.7f / 10052;
  // // adc3 = ads.readADC_SingleEnded(3)*22.7f / 10052;
     adc0 = ads.readADC_SingleEnded(0);
     adc1 = ads.readADC_SingleEnded(1);
     adc2 = ads.readADC_SingleEnded(2);
     adc3 = ads.readADC_SingleEnded(3);

   Serial.printf("AN0: %5d \tAN1: %5d \tAN2: %5d \tAN3: %5d \n", adc0,adc1,adc2,adc3); 
delay(1000);
