For a better usability of the EzoGateway a custom PCB was designed, which replaces the Whitebox T3 HAT and adds some features. Designed as an inverted HAT, the PCB carries up to 3 Atlas Scientific EZO™ circuits in addition to the Raspberry Pi.
| Count | Feature | Connector | Description |
|---|---|---|---|
| wide range power supply | Wago MCS or coaxial power connector | 9 - 36 VDC (min. 5 W) | |
| 2 | isolated EZO sockets | BNC | for pH and O.R.P. circuit |
| 1 | non-isolated EZO sockets | BNC | for RTD circuit |
| 2/4 | external 1-wire channels | Wago MCS | for digital temp. sensors |
| 1 | on-board temp. sensor | on seperate int. 1-wire ch. | |
| expansion port (I2C, SPI) | .10" pin header | e.g. for relais expansion | |
| 4 | status LEDs | ||
| fits for ALUBOS 1000 |
Top and bottom view of the first PCB manufactured. In production since 20.02.2020.
First built up "EzoGateway" from 12.03.2020. Equipped with RaspberryPi and EZO™ devices for pH, ORP and RTD) measurement.
| LED | Description | Behavior |
