UNO PLUS - Arduino Uno R3 compatible

UNO PLUS is a development board compatible with the Arduino UNO R3, an improved & enhanced alternative solution for Arduino UNO R3.

What's on the UNO PLUS:

1. ATMEGA328P-AU
2. AMS1117-3.3 : 3.3V voltage regulator
3. NCP1117ST50T3G : 5V voltage regulator
4. FT232RL : USB to UART convertor
5. Arduino interface
• compatible with standard Arduino interface with two additional analog inputs A6 (config the CFG), A7
• solder pads provided, supports prototype breadboard
6. ICSP interface
7. MICRO USB connector : for uploading program OR serial port debugging
8. Power output header : 3.3V OR 5V, voltage level configured by the onboard power configuration switch, used as power output OR common-grounding with other boards
9. FT232 pins : for burning Bootloader into the microcontroller
10. DC input : 7V ~ 12V
11. Reset button
12. Power indicator
13. Serial port Rx/Tx indicator
14. User LED
15. Power configuration switch : for configuring the operating voltage
16. Bootloader selection switch
• turn ON : the board will reset when power-up OR other USB devices were detected connecting to the PC
• turn OFF : the onboard program runs immediately when power-up, and the board will not reset when other USB devices were detected connecting to the PC
