3Pcs CJMCU-MCP4725 I2C DAC Breakout Development Board Module Description: You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The CJMCU-MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects! This version of the CJMCU-MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout, changes the overall board dimensions to better fit your projects, and a few more minor tweaks. This board breaks out each pin you will need to access and use the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope or any other device you need to hook up to the board. Also on board are SCL, SDA, VCC, and another GND for your basic I2C pinout. Additionally, if you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this. Feature: 12-bit resolution I2C Interface (Standard, Fast, and High-Speed supported) Small package 2.7V to 5.5V supply Internal EEPROM to store settings Package included: 3 x CJMCU-MCP4725 I2C DAC Breakout Development Board Module

Scope: Mainly used in battery (9V or 12V) voltage monitoring, simple and practical, support sound and light alarm. Features: When the buzzer low voltage will "DiDiDi" sounds and the red LED lights up, when the battery voltage rise above to the set value, buzzer will stop alarm. Size: 2.9 x 3 cm The main chip: LM358 9V Battery: When a battery over-discharge (battery voltage drops below about 8V), the red lights and the buzzer calling to achieve sound and light alarm, to achieve control battery discharge status, prevent over-discharge battery, and damage battery; 12V Battery: When a battery over-discharge (battery voltage less than 10.4V), the red lights and the buzzer calling to achieve sound and light alarm, to achieve control battery discharge status, prevent over-discharge battery, and damage battery; Advantages: With a sound and light alarm, simple and practical. The module input with reverse protection, if reverse polarity power input will not burn. But without overvoltage protection, if the input exceeds 15V, the chip above the module will burn out. Adjustment method: 9V Battery: Input 9V, the LM358 voltage adjustment between 2 feet and 4 feet to about 5.78V, the alarm voltage is 8V (we has set it before shipment, so you don't need to adjust it again). Clockwise adjustment, 2 feet and 4 feet voltage is reduced, the sensitivity increased. 12V Battery: Input 12V, The LM358 voltage adjustment between 2 feet and 4 feet to about 6.05V, the alarm voltage is 10.4V (we has set it before shipment, so you don't need to adjust it again). Clockwise adjustment, 2 and 4 feet voltage is reduced, the sensitivity increased. Package includes: 3 x Battery Over-discharge Protection Module

FAST AFFORDABLE COURIER SHIPPING TO SOUTH AFRICA Features: LC 5A Over-current protection Sensor module uses current transformer to collect the AC signal to achieve the relay over-current signal output within 0-5A. Relay pull while over-current, relay released while not over-current. Users can use the relay COM, NC, NO three ports to control the external circuit on and off, in order to achieve over-current protection. Functions: -Current detection resolution can change the parameter of resistance parameters; -Output over-current switching signal output; -Over-current signal setting critical point adjustable, Specifications: Operating voltage: DC12V Operating current: Operating frequency range: 20Hz ~ 400Hz Output mode: switch signal output Maximum detection wire diameter: 5.2mm Mounting hole: hole diameter is 3mm, hole distance is 52.5mm Operating environment: -40 ￢ﾄﾃ ~ +85 ￢ﾄﾃ The current detection range:AC0.3A-5A Board size: 38 * 44mm The Board Description: VCC: Operating voltage positive; GND:Operating voltage negative; NO: Normally open, the relay pulls before the NO and COM disconnect, short-circuit after the suction; COM: common, relay common interface; NC: Normally closed, the relay before the NC and COM short-circuit, pull off after. Using Instructions: By setting the potentiometer to set the overcurrent protection point, the clockwise adjustment reduces the detection current. As bellows: 1. Measured the wire through the current transformer, connect VCC and GND to DC12V power supply; 2. Adjust the potentiometer, when you hear the sound of the relay pull (can be measured with a multimeter COM and NO whether was turned on, if connected to the relay means activated), then reduce or cut off the current flowing that through the tested wire, if the relay release at this time that over-current protection point has been identified (available to multimeter COM and NC measurement whether is connected, if connected to the relay means been released); 3. When reduce or cut off the current flowing through the wire, the relay is not released, will still need to continue to adjust the potentiometer to find the over-current protection point.
