Waveshare AlphaBot Bluetooth - a robot construction kit for Arduino

Description

AlphaBot set for building an Arduino or Raspberry Pi based robot. The set includes a number of modules that perform tasks such as line tracking, obstacle avoidance, speed measurement, infrared control. The robot contains modular solutions that allow easy and quick connection of components, without the problems of correct connection using wires. The kit includes a modified version of Arduino UNO R3, named UNO PLUS. It is modernized but still compatible with classical Arduino software and electronics. In addition, the kit also includes an Arduino (Accessory Shield) expansion board and a Bluetooth module.

3. NCP1117ST50T3G 5 V voltage regulator
   
4. FT232RL USB to UART converter
   
5. Arduino interface
   
   • compatible with the standard Arduino interface with two additional analogue inputs A6 (configurable in CFG) and A7
   • additional soldering pads, helpful in prototyping
6. ICSP interface
   
7. Micro USB connector for programming or as a serial port
8. 3.3 V or 5 V power outlets, the voltage level is configured using the configuration jumper
9. FT232 pins for burning the bootloader in the microcontroller
   
10. DC power supply: 7 - 12 V
    
11. reset
    
12. Power LED
    
13. Serial data transmission LED Rx / Tx
    
14. LED for the user (programmable)
    
15. Fast 500 mA fuse
    
16. Configuration voltage jumper, configuration between 3.3 V and 5 V
17. Bootloader mode switch
    
    • On - the board will reset when the power is turned on or when other USB devices connected to the computer are detected
    • Disabled - the program on the board will start immediately after the power is turned on and the board will not reset after detecting other USB devices connected to the computer

UNO PLUS features and comparison to UNO R3

UNO PLUS tile is a development board compatible with Arduino UNO R3. Thanks to the introduced modifications, it is an excellent solution replacing Arduino UNO R3 and allowing much more.
