Keyestudio Mega (core to ATmega2560) is a development board (used with16MHz crystal oscillator ) of microcontroller. There are 54 I/O (input/output ) digital interfaces (of which 14 are PWM outputs), 16 analog inputs and 4 UART (hardwareserial ports). With its bootloader, program can be downloaded directly with USB and you don’t need to use other external programmer. It can be driven directly by USB, or AC-to-DC adapter and battery.
Design of Power Supply :
There are two choices (direct power supply trough USB or external power supply) for the power supply system of Arduino Mega, and they can be Automatic switched. External power supply can be AC-to-DC adapter or battery. Voltage input of this control board is 6V~12V, but if the supplied voltage is greater than 12V, the voltage stabilizing device will be likely to be overheated and damaging Arduino MEGA. So we suggest the power supply should be 6.5~12V in operation and recommended supply is 7.5 or 9V.
Input Voltage (recommended):7-12V
Input Voltage (limits):6-20V
Digital I/O Pins:54 (of which 15 provide PWM output)
Analog Input Pins:16
DC Current per I/O Pin:40 mA
DC Current for 3.3V Pin:50 mA
Flash Memory:256 KB of which 8 KB used by bootloader
Clock Speed:16 MHz

Спасибо продавцу получил товар, все соответствует заказу! Продавец очень порядочный! Рекомендую...
Good. Good. All corretto taking into account the problems of the pandemic situation.
Object as description. Excellent quality and fast shipment
Good product. Thank you.
It came very quickly. I'll check it out
Good quality product.
It came in a mint box, you could pack it better, the chance of breakage of the fee is very large. The soldering quality is good. I bought it on recommendation.
Quality soldering, flux everywhere is washed, works without complaints, not the first time I take from this store, it is better to overpay for quality.
Super fast delivery, to Moscow only 10 days. The fee is made qualitatively. I did it without problems.
The outer packaging was notorious (thanks to the Russian Post), but inside everything turned out to be a whole. Arduina looks good, too. Connected to the laptop, like the LED flashing, drivers additionally did not need any.
I'm very satisfied. High quality product and fast shipping. Thanks.
