-Figure shows the general schematics for the electronic measurement board developed.
-We have developed a complete "plug and play" measurement board. To measure electrical resistivity with Raspberry Pi.
-two ADS1115 were used,one for the voltage measurement one for the current measurement, as proposed by Florsch [7]. The ADS1115
-is a 16-bit ADC (Analog-to-Digital Converter), with an adaptable gain. The advantage of ADS1115 is that the
-input signal value could lie between - to + 6.114 V. For the current measurement we have directly integrated the INA282 component,
-which allows to realize precise current measurement around a shunt resistor. The assembly steps are described in the following steps:

two ADS1115 were used,one for the voltage measurement one for the current measurement, as proposed by Florsch [7]. The ADS1115
is a 16-bit ADC (Analog-to-Digital Converter), with an adaptable gain. The advantage of ADS1115 is that the
input signal value could lie between - to + 6.114 V. For the current measurement we have directly integrated the INA282 component,

+<p>The multiplexing of the channels is a mechanical multiplexing based on OMRON’s manufacturing relays (G5LE-1-VD 12 VDC). Each relay is combined with
+a ZVN4206A power MOFSET. The raspberry has only 30 GPIOs, which is not enough to activate all the 64 electrodes, which represent 512 GPIOs.
+We used gpio expender I2C (MCP23017). We have associated these components with an I2C muliplexer of type type TCA9548A from adafruit.
+This combination allows to go up to 512 GPIOs and up to 128 electrodes. Each card has its own digital address between 0X70 and 0X77.
+In the following presentation for an Ohmpi 64 electrodes, we will use the addresses 0X70 for channel A, 0X71 for channel B, 0X72 for channel M and 0X73 for channel N.
+0X73 for the N channel. 4 MUX board will be needed to multiplex an Ohmpi 64 electrodes.</p>

+The multiplexing of the channels is a mechanical multiplexing based on OMRON's manufacturing relays (G5LE-1-VD 12 VDC). Each relay is combined with
+a ZVN4206A power MOFSET. The raspberry has only 30 GPIOs, which is not enough to activate all the 64 electrodes, which represent 512 GPIOs.
+We used gpio expender I2C (MCP23017). We have associated these components with an I2C muliplexer of type type TCA9548A from adafruit.
+This combination allows to go up to 512 GPIOs and up to 128 electrodes. Each card has its own digital address between 0X70 and 0X77.
+In the following presentation for an Ohmpi 64 electrodes, we will use the addresses 0X70 for channel A, 0X71 for channel B, 0X72 for channel M and 0X73 for channel N.
+0X73 for the N channel. 4 MUX board will be needed to multiplex an Ohmpi 64 electrodes.

+<p>The multiplexing of the channels is a mechanical multiplexing based on OMRON’s manufacturing relays (G5LE-1-VD 12 VDC). Each relay is combined with
+a ZVN4206A power MOFSET. The raspberry has only 30 GPIOs, which is not enough to activate all the 64 electrodes, which represent 512 GPIOs.
+We used gpio expender I2C (MCP23017). We have associated these components with an I2C muliplexer of type type TCA9548A from adafruit.
+This combination allows to go up to 512 GPIOs and up to 128 electrodes. Each card has its own digital address between 0X70 and 0X77.
+In the following presentation for an Ohmpi 64 electrodes, we will use the addresses 0X70 for channel A, 0X71 for channel B, 0X72 for channel M and 0X73 for channel N.
+0X73 for the N channel. 4 MUX board will be needed to multiplex an Ohmpi 64 electrodes.</p>

+The multiplexing of the channels is a mechanical multiplexing based on OMRON's manufacturing relays (G5LE-1-VD 12 VDC). Each relay is combined with
+a ZVN4206A power MOFSET. The raspberry has only 30 GPIOs, which is not enough to activate all the 64 electrodes, which represent 512 GPIOs.
+We used gpio expender I2C (MCP23017). We have associated these components with an I2C muliplexer of type type TCA9548A from adafruit.
+This combination allows to go up to 512 GPIOs and up to 128 electrodes. Each card has its own digital address between 0X70 and 0X77.
+In the following presentation for an Ohmpi 64 electrodes, we will use the addresses 0X70 for channel A, 0X71 for channel B, 0X72 for channel M and 0X73 for channel N.
+0X73 for the N channel. 4 MUX board will be needed to multiplex an Ohmpi 64 electrodes.

+The multiplexing of the channels is a mechanical multiplexing based on OMRON's manufacturing relays (G5LE-1-VD 12 VDC). Each relay is combined with
+a ZVN4206A power MOFSET. The raspberry has only 30 GPIOs, which is not enough to activate all the 64 electrodes, which represent 512 GPIOs.
+We used gpio expender I2C (MCP23017). We have associated these components with an I2C muliplexer of type type TCA9548A from adafruit.
+This combination allows to go up to 512 GPIOs and up to 128 electrodes. Each card has its own digital address between 0X70 and 0X77.
+In the following presentation for an Ohmpi 64 electrodes, we will use the addresses 0X70 for channel A, 0X71 for channel B, 0X72 for channel M and 0X73 for channel N.
+0X73 for the N channel. 4 MUX board will be needed to multiplex an Ohmpi 64 electrodes.
