Parameters of Control Kit

1. Mega 2560 Development Board R3

(Compatible with CH340G improved USB power supply)

• 1. Replace ATMEGA8U2 with ATMEGA1 6U2 chip in 2011, ISP. The flash capacity is doubled, which facilitates more powerful function expansion and development needs. In addition to the traditional USB to serial port function, ATMEGA1 6U2 also allows users to define other functions , for example, buyer can configure the USB port as a mouse and keyboard,Game joysticks, cameras, and more.
• 2.SDA and SCL are added to the external interface based on the 2011 version.
• 3.RESET circuit is improved compared to the 2011 version. Prevent RESET from accidentally resetting. The circuit is more stable.

Power design

There are two options for Mega's power supply system, USB direct or external power supply .

The selection will switch automatically. External power supply can choose AC-to-DC adapter or battery,

The limit voltage range of this control board is 6V ~ 12V, but if the voltage provided is less than 6V,the 1/0 port may not be able to provide a voltage of 5V, so there will be instability;

If the voltage is greater than 12V, the voltage regulator may be overheated and more likely to damage Arduino MEGA.

Therefore, the recommended operating power supply is 6.5 ~ 12V, and the recommended power supply is 7V or 12V.
