F-0 mode: Display the output voltage: F-1 mode: Display the input voltage: F-2 mode: Alternating display input and output voltage: Applications: 1. Used as an ordinary step-down module with overcurrent protection Instructions: 1) Under no load condition, adjust "ADJ-V" of constant voltage potentiometer to make the output voltage reach the voltage value you want; 2) Direct short-circuit module output (find a thick wire or tweezers shorted to the output, Note: short-time do not adjust the voltage), then adjust the "constant current potentiometer ADJ-I" to make current value reaches the preset over-current protection value; or connected to the load can also adjust the current. (Such as on-board ammeter shows the current value is 4A, then the module maximum current is limited to 4A, when the current to 4A, the constant current red indicator light) 3) Connected to the load, work. 2. Used as a battery charger Instructions: 1) Determine the battery float voltage and charge current; (If the lithium battery parameters is 3.7V / 2200mAh, then the float voltage is 4.2V, the maximum charge current 1A, or 2200mA) 2) Under no load conditions, adjust the "constant voltage potentiometer ADJ-V" so that the output voltage reach to float voltage; 3) Direct short-circuit module output (find a thick wire or tweezers shorted to the output, Note: when short-circuit do not adjust the voltage), then adjust the "constant current potentiometer ADJ-I" to make the current value to the preset value of the charging current; or connected to the load can also adjust the current. 4) Charging turn lights current factory default is 0.1 times charging current; (battery during charging the current is gradually reduced, and gradually from constant current charging to constant voltage charging, if the charge current is set to 1A, then when the charge current is less than 0.1A, the charging yellow indicator light is off, full of charge blue light is lit, then the battery charge is complete), when charging is completed, please disconnect the battery terminal, then disconnect the input to prevent the battery backflow damaged the module! 5) Connected to the battery, charging. 3. Uesd as a constant current LED driver module Instructions: 1) Determine that you need to drive the LED operating current and maximum operating voltage; 2) Under no-load conditions, the regulation "constant voltage potentiometer ADJ-V" so that the output voltage reach to LED operating voltage; 3) Direct short-circuit module output (find a thick wire or tweezers shorted to the output, Note: short-time do not adjust the voltage), then adjust the "constant current potentiometer ADJ-I" so that the current value reach to the preset LED operating current; or connected to the load can also adjust the current. 4) Connected to the LED, and test. Note: The constant current adjustable current, the actual load current must be greater than the set current to enter the constant current mode, otherwise is the constant voltage state of work, rather than the current transferred to 2A, that means connected to any device has changed to 2A.

Geekcreit™ UNO R3 ATmega328P Board + 2.4 Inch TFT LCD Touch Screen Module For Arduino Note: The 2.4 inch LCD Touch Screen Module is the newest version which has more stable chip with touch pen. (Update in 2015-09-17, CN warehouse at present) Please pay close attention to the bottom of the forum, we will post the most newest driver there, if your LCD screen can not work, please contact us to get the useful driver, thank you! UNO R3 ATmega328P Board: Description: UNO R3 board is 100% compatible with original Arduino, now it has perfect quality and performance. Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements theProcessing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). This is the new Tosduino Uno R3. In addition to all the features of the previous board, the Uno R3 now uses an ATmega16U2 instead of the ATmega8U2 chip. This allows for faster transfer rates, no drivers needed for Linux or Mac (inf file for Windows is needed), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. Note: The TOSduino Uno R3 requires the Arduino 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However, the first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine. The small chip is ATmega16U2, the 28 pin DIP socket chip is ATmega328-pu. Interaction: 2013-08-08 Cathal Keady's question: Can item SKU066313 be powered directly from using the USB port or do I need to purchase a power supply for it. my answer: This item has not built-in battery, so it can not be charged. With that USB cable connect to computer, you can use it.

Features: - Acrylic clear case shell, high transmittance to be looked through - Built in for ARM 32 bit processor, accurate detection & system fluency - 2.8" TFT screen, colorization display, wide angle vision up to 180° - High sensitivity sensor ensures the high accuracy in data collections - Semi-closing design performs excellent in heat radiation, long-life use - Multipurpose in air quality detection in HOCO, CO2, PM1.0, PM2.5, PM10.0, AQI, temperature&humidity, suspended particulate matter - Real-time detection results will be shown on screen in corresponding colors related to collected data - Lightweight, easy to use and be a straightaway in data interpretation - Power supply in DC 5V universal, USB socket, car charger, power bank, etc - Suitable for home/office and car or part scope on air quality detection Working Principle: - Multi-angle Laser Scattering Detection, laser irradiation in the suspended particulate matter in the air and generate scattering. Scattered light will be collected in a specified angle at the same time. According to the scattering intensity, time-varying curves can be obtained through the sensor. Being processed by the microcomputer processor, equivalent particle diameters and the number of suspended particulate matter with different sizes in per unit volume can be obtained.
