TDS Meter

- Operating voltage: 3.3~5.5V
- Output signal: 0~2.3V
- Connection interface: XH2.54-2P
- TDS measurement range: 0~1000ppm
- Waterproof probe for long-term immersion in water.
- The TDS value can reflect the cleanliness of water and can be applied to water quality testing in the fields of domestic water and hydroponics. In general, the higher the TDS value, the more lysate is contained in the water and the more unclean the water. It is compatible with Arduino boards.

I2C Module

- The board has a PCF8574 I2C chip that converts the I2C data from an MCU into 4-bit parallel data and control bits required by the LCD display.
- By default, the industry standard HD44780 compatible 16 x 2, 16 x 4 and 20 x 4 character LCD displays require 4 or 8 parallel data lines to drive them along with a couple of pins for chip select and chip enable. This consumes a lot of pins on the MCU. This adapter board reduces the data pin requirements to only 2 pins which can also be shared with other I2C devices.
- It has Contrast controlling potentiometer

Coupler

- 5mm to 8mm and 6.35mm to 8mm inner diameter Flexible Shaft Coupler
- Outer diameter: 20mm
- Height: 25mm
- These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce bending effects.
- The way they are cut, create a spring effect in the X Y & Z linear axis but not in the rotational axis. That means that you will not get increased backlash – so they’re suitable for precision CNC work.
- Comes with two sets of double set-screws (two per side) for secure attachment.
