Product description
Package contents:
1 x Load cell 0-5KG
1 x HX711 24BIT Precision ADC Module on breakout board
10 x Breakaway header pins for HX711 connection
Everything you need to take accurate force measurements with and Arduino, Raspberry Pi, or other microcontroller in one complete package!

Information:
Load cell - Sturdy aluminum alloy construction. Strain gauges pre-attached with strain relieved wires. Accurately measures forces from 0-5kg (0-11 lb).
HX711 - This top of the line load cell amplifier mounted on a breakout board pairs perfectly with the load cell to provide fast, accurate force measurements. It measures small changes in the resistance of the strain gauges mounted to the load cell and passes these values directly to any microcontroller (like an Arduino or Raspberry Pi).
Load cell specs:
-Wire leads pre-attached, 22 cm (8.5 in) long
-Dimensions 12.7 mm high, 12.7 mm wide, 80 mm long (0.5 in x 0.5 in x 3.15 in)
-4 mounting holes, 15 mm spacing on each side. One side both holes tapped M4 thread, the other side both holes tapped M5 thread.

HX711 specs:
-Operation Voltage: 2.7V–5V
-Operation Current: < 1.5mA
-Mounted on breakout board
-Includes breakaway headers for connection, soldering required

Connections:
Red to E+
Black to E-
Green to A+
White to A-

Description
Connect your Raspberry Pi to GSM/GPRS cell phone network with this shield. This Raspberry Pi GSM/GPRS shield lets you connect to the internet in the areas where is devoid of Wi-Fi or Ethernet. Quectel M66 module is the heart of this Raspberry Pi add-on. M66 is a quad-band GSM/GRPS module based on the latest 2G chipset which has the optimal performance in SMS & Data transmission and audio service even in harsh environment. You can plug a headset and make a call to someone easily.

Both UART and USB communication with the M66 GSM module is available. The shield can be used easily via easy-to-use AT commands.

The compact form factor, low power consumption and extended temperature make M66 one of the best choices for M2M applications such as wearable devices, automotive, industrial PDA, personal tracking, wireless POS, smart metering, telematics, and more.

Features
Fully compatible with Raspberry Pi models that have the 40-pin GPIO header (3, 2, B+, A+, Zero)
High Data Speed: GPRS Multi-slot class 12, 85.6kbps downlink and 85.6kbps uplink data rates
Quad-band: 850/900/1800/1900MHz
Built-in PCB antenna, also there is an external antenna port available
Supported Protocols: TCP/ UDP/ PPP/ FTP/ HTTP/ SMTP/ CMUX/ SSL
Quectel’s QuecLocator Feature, lets you get the location without GPS/GNSS
Extremely low standby power consumption by M66, 1.3mA at DRX=5
Efficient and low quiescent current regulator circuit can hold up to 3.6A
Bluetooth Function, V3.0 specification, SPP and OPP profiles available.
Micro SIM Card socket can easily reachable on the downside of the shield.
Can be used standalone with PC/Laptop over micro USB, without stacking with Raspberry Pi thanks to FTDI chip on the shield.
Sending/Receiving standard V.25ter AT commands over UART port to Raspberry Pi is available
Working temperature range: -30°C to +80°C
