4tronix Robo:bit Robotics Controller Board For BBC Micro:bit

Product Description

4tronix Robo: Bit for BBC micro:bit & Accessories
- 4tronix ROBOBIT, The Robo: Bit robotics controller (75-0133) is a ready-assembled robotics controller board that's ready to be used with your BBC micro:bit, just add battery power (3 or 4 AA is ideal, but not included) & motors of your choice to make your own DIY robot. Use a small box, ice-cream carton or similar to house everything & you can build a really affordable robot for your school, coding club or home. Robo: Bit has been cleverly designed so that with a few hexagonal pillars & screws, you can fit the motors, battery box, front casters, line following sensors & even ultrasonic distance sensors & have a very neat & simple robot! Robo: Bit uses the ever popular DRV8833 motor driver which means that you can use most small motors that operate in the 3 to 6V range. Connections are provided for lots of the BBC micro:bit pins, & all have immediate 3-pin access to power (3.3V) & ground. There are three separate pins for 5V if you need the extra voltage (but don't feed back 5V to the micro:bit as it won't like it!). This is the GVS (Ground, Volts, Signal) system for sensors & servos etc. On the left side of the board (the 'front' of the robot) is a set of 4 offset holes into which you can simply poke an HC-SR04 ultrasonic distance sensor. The offset holes & gold plating ensure a good connection, but you can also solder it in permanently for added robustness. 4tronix Robo:bit Robotics Controller Board for BBC micro:bit
