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.

If you need only the CT, please check this: >>> Here Many buyers are response: Why test data is wrong? Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that? Answer: There are three types of power: Active Power (P represents / unit W) Reactive power (Q represents / unit Var) Apparent power (S represents / unit VA) Here that We only talk about Active Power, others please google it: P = U * I * cosφ, cosφ it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time, P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.) P U*I, As for how much to keep the power factor related to the specific, Different for each appliance power factor.
