Most DC motors with a microcontroller is an H-Bridge. The Jetpack quickly adds an H-Bridge to your micro:bit makey:bit. (micro:bit/Makey:bit/Motors/Servos Solder Separately)

JetPack components are fully supported in in the most common micro:bit programming environments like MakeCode, microPython, etc., enabling students to easily code projects in robotics or physical computing where multiple motors are needed.

Control:

• Up to 4 Servos
• 2 DC Motors
  
• I2C and more neopixels
• Includes built-in OLED screen
