The AlphaBot2 robot kit is designed to use with the BBC micro:bit (not included) and features a great list of popular robot features including line tracking, obstacle avoiding, ultrasonic ranging, Bluetooth remote control (via Android app), RGB LEDs, a buzzer and more! Thanks to the highly integrated modular design, it's very easy to assemble without any soldering or fiddly wiring. After a few minutes assembling the kit, you're ready to code! The user guide can be found here. Important notes: * This robot requires a BBC micro:bit which is not included but can be purchased here. * 3.6V 14500 rechargeable lithium batteries with at least 800mAh capacity are required but not included (coming soon to the store!). AA batteries will not work! Features AlphaBot2 employs a 2-layer structure to provide excellent stability and compatibility. AlphaBot2-Base (the lower base chassis) * 5-ch infrared sensor, analogue 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 colour lighting AlphaBot2 for micro:bit (the upper adapter board for the controller) * micro:bit dedicated connector, for easily connecting with the micro:bit * MP1584 voltage regulator, provides stable 5V output * RT9193-33 voltage regulator, provides stable 3.3V voltage to the micro:bit * TLC1543 AD acquisition chip, allows the micro:bit to use analog sensors * PCA9685 PWM control chip, I/O expander * Onboard buzzer to play music * Dimensions: 110xx x 98mm Kit contents * 1x AlphaBot2 for micro:bit (adapter board) * 1x AlphaBot2-Base (base chassis) * 1x Ultrasonic sensor * 1x FC-20P cable 8cm * 1x USB type A plug to micro B plug cable * 1x AlphaBot2 for micro:bit screws micro:bit not included What's on the AlphaBot2 Base 1) AlphaBot2 control interface: for connecting sorts of controller adapter board 2) Ultrasonic module interface 3) Obstacle avoiding indicators 4) Omni-direction wheel 5) ST188: reflective infrared photoelectric sensor, for obstacle avoiding 6) ITR20001/T: reflective infrared photoelectric sensor, for line tracking 7) Potentiometer for adjusting obstacle avoiding range 8) TB6612FNG dual H-bridge motor driver 9) LM393 voltage comparator 10) N20 micro gear motor reduction rate 1:30, 6V/600RPM 11) Rubber wheels diameter 42mm, width 19mm 12) Power switch 13) Battery holder: supports 14500 batteries 14) WS2812B: true color RGB LEDs 15) Battery charging indicator 16) 5V USB battery charging port 17) Power indicator What's on the AlphaBot2 for micro:bit (upper layer) 1) micro:bit connector 2) AlphaBot2-Base header: for connecting with the base board 3) RT9193-33: 3.3V voltage regulator, stable power supply for the micro:bit 4) PCA9685: PWM control chip, I/O expander, I2C interface 5) TLC1543: 10-bit AD acquisition chip, allows the micro:bit to use analog line tracking sensor 6) Buzzer 7) MP1584 5V voltage regulator Resources * Product Wiki and user guide https://elecena.pl/product/22720708/alphabot2-robot-kit-for-bbc-micro-bit-discontinued 2023-03-07 https://elecena.pl/product/22720708/alphabot2-robot-kit-for-bbc-micro-bit-discontinued 2023-12-27 https://elecena.pl/product/22720708/alphabot2-robot-kit-for-bbc-micro-bit-discontinued 2024-01-18 https://elecena.pl/product/22720708/alphabot2-robot-kit-for-bbc-micro-bit-discontinued 2024-04-30 https://elecena.pl/product/22720708/alphabot2-robot-kit-for-bbc-micro-bit-discontinued 2024-09-19
