Description: For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter. The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single ended inputs. Feature: Wide supply range: 2.0V to 5.5V Low current consumption: Continuous Mode: Only 150uA Single-Shot Mode: Auto Shut-Down Programmable data rate: 8SPS to 860SPS Internal Low-drift voltage reference Internal oscillator Internal PGA I2C interface: Pin-Selectable Addresses Four Single-ended or two differential inputs Programmable comparator This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers Package included: 3 x I2C ADS1115 16 Bit ADC 4 Channel Module

Description: The IIC 2004 LCD display module is a 4 line 20 character LCD module not only set the contrast control knob selector switch also has a backlight and IIC communication interface. For Arduino beginners, not for the cumbersome and complex LCD driver circuit connection and a headache, the real significance of this LCD module will simplify the circuit, this module directly into the Arduino Sensor Shield V5.0 sensor expansion board IIC device interface can, GM 4P sensor connection cable, programmed through the Arduino controller, you can easily identify the slogan, sensor data records. Specification: Supply voltage: 5V Interface: I2C I2C address: 0x27 or 0x3F Pin definition: GND, VCC, SDA, SCL Contrast adjust: potentiometer The module is a low-power consumption character LCD module with a built-in controller The module can be easily interfaced with a MCU Display format: 20 Characters x 4 lines Fully assembled and tested serial LCD 20 x 4 module White text, blue backlight It is fantastic for Arduino based project Size: 9.8 x 6 x 1.2mm Package included: 3 x 2004 LCD display module

Description: Operating voltage: 3.3V Measuring range: 4-8 inch (10-20cm) I2C Interface Built-in APDS-9960 sensor, providing ambient light and color measurement, proximity detection and non-contact gesture detection. With this RGB and gesture sensor, you can control a computer, a microcontroller, a robot, and it's much more powerful than a simple credit card with your hand! The APDS-9960 is a serious little piece of hardware with built in UV and IR blocking filters, four separate diodes sensitive to different directions, and an I2C compatible interface. For your convenience we have broken out the following pins: VL (optional power to IR LED), GND (Ground), VCC (power to APDS-9960 sensor), SDA (I2C data), SCL (I2C clock), and INT (interrupt). Each APDS-9960 also has a detection range of 4 to 8 inches (10 to 20 cm). Can be applied to ambient light and RGB color sensor, close to detection, gesture detection. Package included: 3 x Gesture sensor

Description:   The development board using Micro USB cable supply, compatible with smart phone lines, data lines is simple and easy to get, but not USB Mini line-powered.   STM8S core board of the main features:   Use STM8S103F3P6 as the master IC You can use 2.54 pin on the board or power supply pad, the pad when using power supply, input voltage range 4.5V-15V, can output to the outside through pin 3.3V Note: 5V pin's voltage is the input voltage of the module Leads to all pins, the pins next to the pin marked the label, with a reset button, power LED, and the program demonstrates LED, small but perfectly formed Support SWIM debug mode   Technical Information:   The core board schematics (PDF format) and tested source. Burned into the test program, LED flashes, allowing you to detect the core board is working properly Provide at IAR and STVD two development environments register operation and routine operation of the library functions. Timer routine, UART transmit routine, UART receive routines, clock switching routines, AD routines and so on STM8 Applications STM8 package library IAR development environment, STVP programming software   STM8S103F3P6 performance comparison:   STM8S003F3 chips only 128 bytes of EEPROM, STM8S103F3 640 bytes STM8S003F3 chip FLASH erase only 100 times, STM8S103F3 can erase ten thousand times STM8S103F2 chip FLASH only 4K bytes, STM8S103F3 have 8K bytes Conclusion: STM8S003F3 only suitable for mature products, STM8S003F3 core board is not suitable for development. However STM8S103F3 suitable for the development of the use of, our board of this development is the use of this chip Size:28mm*17mm*5mm Package included: 3 x STM8S103F3P6 System Board
