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

Introduction:
N9200B is a MP3 chip that provides serial port,which perfectly integrates MP3 and WMV hard decoder chips.
It includes the N9200A and N9200B Music MP3modules,and the software supports TF driver, supports the computer to update the content of SPI-flash directly, and supports the FAT16 and FAT32 file systems.
Through a simple UART serial command or a first-line serial port instruction to play the specified music, and how to play music and other functions, without the tedious underlying operation, good sound quality, easy to use, stable and reliable is the biggest feature of this product.
In addition, the chip is also a product of deep customization, which is a low-cost solution for fixed voice playback.
