Description: CKD0002 Cokoino V1 mainboard Compatible with arduino UNO R3
Characteristic: This is an upgrade controller board based on arduino UNO R3, which is fully compatible with arduino UNO R3 and more powerful. Its features are as follows: 1) The most popular type C USB interface: easy to plug and unplug, can be connected to DC5V 2A power supply 2) CP2102 USB to serial chip: compatible with various PC systems 3) DC to DC 5V power supply voltage stabilization system: makes the control board reduce heat and save more power, the maximum output of the control board is 2A current 4) More powerful DC3.3V voltage regulator chip: maximum load 3.3V 500mA 5) Add two analog input ports A6 and A7: connect more modules that output analog signals 6) System voltage selection switch of 3.3V and 5V system: perfect communication with 3.3V or 5V external system
