Power Down consumption on custom board

Development Other Hardware Development
10

OK, trying to disable individual functions before stopping each function clock:

#include <avr/power.h>
#include <avr/sleep.h>

void setup()
{                
  byte i;
  
  // Ensure no floating pins
  for(i=0; i<20 ; i++)
  {
    pinMode(i, OUTPUT);
    digitalWrite(i, LOW);
  }
  
  // Power-down board
  set_sleep_mode(SLEEP_MODE_PWR_DOWN);
  
  sleep_enable();
  // Disable functions 
  power_adc_disable();
  power_spi_disable();
  power_twi_disable();
  power_usart0_disable();
  power_timer0_disable();
  power_timer1_disable();
  power_timer2_disable();
  
  PRR = 0xFF;
  
  // Enter sleep mode
  sleep_mode();
}

void loop()
{
}

Consumption is still around 105 uA =(

Thanks guys!
