1. Power supply: 5V (POWER connector) OR 6V~12V (VIN terminal)
2. Servo voltage: 5V
3. Logic voltage: 3.3V
4. Driver: PCA9685
5. Control interface: I2C
6. Dimension: 65mm x 36mm
7. Mounting hole size: 3.0mm

Features:

1. Onboard touch controller, smoother touch experience than solutions that directly use AD pins for touching.
2. SPI interface requires a few pins.
3. Programmable backlight control, power saving.
4. Comes with development resources and a manual (examples for STM32/AVR/PIC).

Features:

1. 4inch IPS screen, 480×800 hardware resolution.
2. Resistive touch control.
3. Compatible and Direct-connect with any revision of Raspberry Pi (except the Pi 1 Model B or Pi Zero, which requires an HDMI cable).
4. Drivers provided (works with your own Raspbian/Ubuntu/Kali/Retropie).
5. Also works as a computer monitor, in this case, the touch panel is unavailable and an HDMI cable is required.
6. HDMI interface for displaying, no I/Os required (however, the touch panel still needs I/Os).
7. 3.5mm audio jack, supports HDMI audio output.
8. The backlight can be turned off to lower power consumption.

Wheatstone bridge formation of Load Cell:

HX711 (24 bit Analog to Digital Converter)

HX 711 is a precision 24-bit analog to digital converter (ADC) specially designed for Weigh scales and industrial control applications to interface directly with a bridge sensor.

Simply connect Load cell wires to the HX711 module based on their color, then connect DAT (Data) pin to Arduino Analog pin A1 and connect CLK (Clock) pin to Arduin0 Analog pin A0, Put Vcc and GND supply from Arduino power source pins.
