- New improvement: clearly printed on the female header connector, more precise and easier to use the wire
- The Uno now uses an ATMega16U2 instead of the ATMega8U2 chip. Faster transfer rates and more memory
- Control using ATMEL ATMEGA328P chip
- 100 percent compatible with the official version, for Arduino uno R3
- We have always cared about the customer experience and improve the product function details
- This AC/DC adapter can apply to most appliances, which the efficient voltage is from 3V to 12V.
- This adapter output is 3V/4.5V/5V/6V/7.5V/9V/12V. You can easily set the voltage by a little key, which included with the adapter.
- Equipped with 6 adapter plugs, the different size will fit for your appliances well, and solve your various problems.
- With safe and multiple function, it's easy to operate, and the adapter is very durable, it's secure to use. [Attention: If you are looking for an Centra Negative 12W Adapter, please kindly search B01N6327JN or www.amazon.com/dp/B01N6327JN.
- This 6 adapters in1, which can largely save your space and the one can replace a lot adapters. Attention: DC Plug Polarity: inner Positive(+), outer Negative(-), Polarity is irreversible.
- The mega is 100 percent compatible with Arduino and most shields designed for the Arduino Mega2560 R3
- The chip is Atmega2560-16au and Atmega16u2, same with the official version
- Stronger reset circuit. Use 5.5 * 2.1Mm dc barrel jack (compatible with 5.5 * 2.5Mm dc barrel jack)
- It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started
- Universal AC Plug-in Adapter Power: 30W
- nput:AC 100V to 240V, 0.2A, 50/60Hz; Output: 3V/4.5V/6V/7.5V/9V/12V,You can easily set the voltage
