Review of the i2c Addresses with the new hardware
New i2c scan is as follow now, after changing the hardware.
AB Electronics ADC PI
Adafruit PWM Hat
pi@raspberrypi:~ $ sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --

60: -- -- -- -- -- -- -- -- 68 69 6a 6b 6c 6d -- --
70: 70 -- -- -- -- -- -- --
Where each address is taken as per the below table:
40: Adafruit 16 Channels PWM Hat
68: AB Electr ADC PI board 1 chip 1
69: AB Electr ADC PI board 1 chip 2
6a: AB Electr ADC PI board 2 chip 1
6b: AB Electr ADC PI board 2 chip 2
6c: AB Electr ADC PI board 3 chip 1
6d: AB Electr ADC PI board 3 chip 2
70: Adafruit 16 Channels PWM Hat.. this must be a second address used by Adafruit 16 Channels PWM Hat
