16 Bit I2C 4 Channel ADS1115 Module 16 Bit I2C 4 Channel ADS1115 Module is mostly used for microcontrollers project which needs an analog-to-digital converter or when you want a higher-precision ADC. ADS1115 16-Bit ADC- provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-end input channels or two differential channels. Additionally, ADC also includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. It can run from 2V to 5V power/logic, can measure a large range of signals and it’s super easy to use. It is a great general-purpose 16-bit converter. The ADS1115 chip is 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 so you can have up to 4 ADS1115 connections on a single 2-wire I2C bus for 16 single-end inputs. Input range programmed control, 6 types input ranges: -0.256V +0.256V -0.512V - +0.512V -1.024V - + 1.024V -2.048V + 2.048V -4.096V +4.096 V -6.144V - + 6.144V Applications: Portable instrumentation Consumer goods Battery monitoring Temperature measurement Factory automation and process controls Package Includes: 1 x 16 Bit I2C 4 Channel ADS1115 Module Specifications: ADC Bit rate 16 Bit Interface type 12C Channels 4 Channel ANO AN1 AN2 AN3 or 2 differential inputs Input voltage 2.0-5.5v Channel input voltage 0-VDD Continuous mode Only 150μA Single-shot mode Auto shut-down Programmable data rate 8sps-860sps Dimensions 18mm*28mm Weight 5g

CH375B U Disk Read Write Module The CH375B U Disk Read Write Module is fully compatible with CH372, CH375. The CH375 firmware has a built in dedicated protocol processing Mass-Storage and can be directly used as the basic unit of reading and writing in sectors USB storage devices. The CH375 dis read module integrated with a 8-bit data bus and read, write, chip and provides  serial communication via serial input, serial output, and interrupt output monolithic/DSP/MCU/MPU connected. With the help of 2 x 8 connectors it can be easily mounted on a MCU.

CH376 USB Host Interface The "CH376S USB read/write module" has a CH376S chip onboard which does most of the hard work for you. All you have to do is send the module some commands from the Arduino and the CH376S chip will do the rest. CH376 supports three communication interfaces: 8-bit parallel, SPI interface or asynchronism serial interface. The USB-DEVICE Mode of CH376 is totally compatible with CH372, the USB-HOST Mode of CH375 is basically compatible with CH375. Also check the CH375B U Disk Read Write Module, a USB Reader Module available on Iotcart. The module facilitates serial communication via serial input, serial output, and interrupt output for monolithic/DSP/MCU/MPU connections. Package Includes: 1 x CH376 USB Host Interface Module Flash Disk Drive RW Module Features of CH376 USB Host Interface Module  Chip CH376 Module  USB Host Interface Module Compatibility CH372 and CH375 Dimensions  4 x 2 x 0.5cms Weight 5 grams

MCP2515 Can Bus Module Board Controlled Area Network of simple CAN is a bus standard that allows a Microcontroller and its peripheral devices to communicate without the need of a host device or a computer. The MCP2515 CAN bus module is designed with an SPI 51 Single Chip Program and features a TJA1050 Receiver. It is created to control a CAN Bus device by SPI interface with your MCU. It is best used by microcontrollers and boards compatible with Arduino like UNO boards.  The MCP2515 CAN Bus Controller is a simple Module that supports CAN Protocol version 2.0B and can be used for communication at 1Mbps. In order to set up a complete communication system, you will need two CAN Bus modules. The MCP2515 CAN bus module consists of standard frames, extended frames, and remote frames. You can use the serial port of the  MCP2515 CAN bus module to view communication data as well.  Pin Details VCC :5V power input pin GND : power ground pin CS : SPI SLAVE select pin (Active low) SO : SPI master input slave output lead SI : SPI master output slave input lead SCLK: SPI clock pin INT: MCP2515 interrupt pin Pin Diagram: Pin Diagram of MCP2515 Can Bus Module Board Applications: Electronic Gear Shift System Automobiles Main Interface in Automation (like industrial) Medical Equipment Robotics Auto Start/Stop of Car Engine Package Includes: 1 x MCP2515 Can Bus Module Board TJA1050 Receiver SPI for 51 MCU Arm Controller Specifications: Model  MCP2515 Can Bus Module Board Transceiver Used  High Speed CAN TJA1050 Oscillator Used  8MHZ crystal oscillator Resistance 120Ω terminal resistance Data Field Type  0 to 8 bytes long data field Dimensions 4 x 3 x 1 cms Weight 0.5 grams

PS2 Keyboard Driver Module PS2 keyboard driver module use a small microcontroller to read the data of the PS2 keyboard. The values will be sent to other equipment for usage via serial, parallel or TWI/IIC output. (Please ensure that the MINI JUMPER of the TWI/IIC ENABLE has been connected.) In a single chip microcomputer project system, there no need to write the keyboard driver, but just read the key information via serial, parallel or TWI/IIC output directly. More convenient. It will output TTL "0" if no keys had been pressed. If the key outputs "1", it will return to "0". The serial, parallel and TWI/IIC can work simultaneously. Please remove the MINI JUMPER if there is no slave on the TWI/IIC bus, or the module cannot work well. working principle PS2 keyboard driver module uses a piece of programed code of MCU as the controller, to read the state of PS2 keyboard keys. When the keyboard is pressed, the LED lights flashing on the PS2 keyboard driver module, at the same time through serial communication and parallel I/O port or TWI/IIC(Through the short circuit cap option),Keys will be output. For example, Press "A" key,serial port output data 0x1c, parallel I/o port output 0x1c by D7-D0. The output scan code can refer to the back of the content. Pop-up output. In addition, two sets of buttons, TTL output when there is no buttons to press the "0", and have a button to press the output "1", after the button pop-up restore "0" (each key on keyboard effectively. In addition to pause/break key. Serial, parallel, TWI/IIC can work at the same time. If there is no connection from the machine on the IIC/TWI bus, please remove short-circuit cap module above. Otherwise, the module will not be able to work properly.
