This product is developed, manufactured, and tech supported by Waveshare.
SAFETY CAUTIONS
- Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
- Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
- Do not mix use old batteries with new ones, avoid using batteries of different brands.
- When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
- Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
- Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
Overview
This AlphaBot2 robot kit is designed to use with an Arduino compatible board R3 PLUS. It features rich common robot functions including line tracking, obstacle avoiding, ultrasonic ranging, infrared remote control, Bluetooth communication, etc.
Thanks to the highly integrated modular design, it is fairly easy to assemble by a snap, no soldering, no wiring. After a few minutes spent on hardware assembing, you're almost there, our open source demo codes is ready to help you get started fast.
R3 PLUS Features
The R3 PLUS is an Arduino-Compatible microcontroller development board.
| R3 PLUS | Official R3 | Remarks | |
|---|---|---|---|
| Operating voltage | 5V/3.3V | 5V | Dual voltage level to support more shields |
| Reset | Lateral | Vertical | Lateral button is easier to use when connecting with shield |
| Bootloader switch | Yes | None | The board can be configured to run program immediately when power-up by the switch |
| USB connector | Micro USB | USB Type B | Micro connector is more commonly used, and shields won't be blocked anymore while connecting |
| DC jack | Low profile | Normal height | Shields won't be blocked anymore while connecting |
| Power output header | Yes | None | Providing 5V/3.3V power output OR common-grounding with other boards |
| 3.3V power output | 800mA Max | 150mA Max | R3 PLUS features higher driving capability |
| Oscillator | Crystal oscillator | Ceramic resonator | Crystal oscillator is suit for applications where accurate clock reference is required |
| ADC channel | 8 | 6 | CFG used as ADC6 by configuration, and ADC7 from the Reserved PIN |
| Connecting with prototype breadboard |
Supported | Not supported | Solder pads is provided for DIY interfaces to connecting with prototype breadboard |
| USB driver | Compatible with all main systems | Doesn't compatible with WIN7/WIN8 Express Edition | Driver will never failed to install thanks to the onboard FT232 |
| Firmware fixing | Supported | Not supported | Firmware can be fixed by using the onboard FT232, no extra programmer is needed |
AlphaBot2 Features
AlphaBot2 employs a 2-layer structure to provide excellent stability and compatibility.
AlphaBot2-Base, the lower base chassis:
- 5-ch infrared sensor, analog output, combined with PID algorithm, stable line tracking
- Onboard modules like line tracking, obstacle avoiding, needs no messy wiring
- TB6612FNG dual H-bridge motor driver, compared with L298P, it's more efficient, more compact, and less heating
- N20 micro gear motor, with metal gears, low noise, high accuracy
- Onboard RGB LEDs, true color lighting, pretty cool
AlphaBot2-Ar, the upper adapter board for controller:
- Onboard Arduino interface, into which Arduino controller can be directly plugged
- 0.96inch 128x64 yellow/blue dual color OLED
- TLC2543 AD acquisition chip
- PC8574 I/O expander, avoid I/O shortage
- Xbee connector, for connecting dual-mode Bluetooth module
