 MUX board v2024
 ****************************************************
 
-**TO BE UPDATED**

-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 expander I2C (MCP23017). We have associated these components with an I2C multiplexer 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 MUX board v2024 uses the same technology than the MUX board v2023, i.e. mechanical multiplexing. However it introduces
+a new level of flexibility by addressing multiple roles (A, B, M, N), which allows to build OhmPi system with multiple of 8 electrodes.
+Users can physically configure the MUX board to address 2 roles (A, B or M, N) or 4 roles (A, B, M, N). With only 32 relays,
+it can address 16 or 8 electrodes, for the 2- and 4-role configuration respectively.
+Given the reduced number of relays, the MUX board v2024 is interfaced with only two MCP23017 I/O expanders.
+This means that up to 4 MUX boards v2024 (i.e. 32-electrode system) can be directly connected to a measurement board v2024.
+A newly introduced I2C extension board (featuring a TCA9548A multiplexer) allows to connect up to 32 MUX board v2024, equating to a 256-electrode system.
+In theory, up to 8 I2C extension boards can be connected to the measurement board, which would allow to pilot 2048 electrodes.
+For obvious practical reasons, such a configuration couldn't be tested and is likely to be limited by the I2C bus being phisically too long,
+which would prevent to reach so many GPIOs.
+In an effort to mitigate supply shortages, a last addition concerns the power mosfet associated with the relays,
+with the possibility to mount two types of components depending on market availability: either ZVN4206A or STP16NF06L.
+
+Here, we will present how to assemble and configure a 32-electrode system, based on 4 MUX-board v2024 set up to address 2 roles / 16 electrodes each.

 **PART B** MUX board address
 ====================================================== 
-To build an ohmpi it is necessary to have 4 MUX boards, with 4 different addresses. It is therefore necessary to identify each board, by assigning an address, which will be allocated in the OhmPi code.
-We present here the addresses selected by default.
+A MUX v2024 comes with 2 I/O expanders (MCP23017) addressing 16 relays each. They can be identified by the Raspberry Pi unit
+with their I2C address ranging 0x20 - 0x27. Two jumpers allow to shift the addresses two by two based on the following combination:

++-------------+-----------------+------------------+
