Built in electrical isolation means that sensors won’t interfere with each other and most outside electrical noise that can interfere with readings is reduced.
3.3V and 5V compatible
stack up to 3 shields to get 6 isolated sensor channels
The sensor circuits are not included.
The isolated channels 2 + 3 can be switched off completely by pulling the respective pin LOW. This will switch off the isolator circuit and the EZO circuit to bring power consumption down to almost 0. The ENABLE pins can be patched to an Arduino digital pin.
The EZO 5-pin devices have an auxiliary pin for interrupts or other I/O functions. The AUX pins for channels 4 + 5 can be patched to an Arduino digital pin.
The Whitebox T2 is COMPATIBLE with all Arduinos with the R3 pin layout. The Mini is 3.3V and 5V compatible.
The Whitebox T2 is compatible with all EZO type circuits from Atlas Scientific that support I2C mode. The Mini will not work with older sensor circuits that support UART only. If you still want to use UART circuits, use the 4-channel Tentacle Shield.
