LORDWORLD

LORDWORLD Raspberry Pi Motor Driver Expansion Board MC33886

SKU CH-Z1QN-V0BC7

A 40-pin GPIO add-on board with an MC33886 H-bridge driver to run DC motors in both directions, a 5 V regulator, IR receiver and protection circuits for 7–40 V input

  • Standard 40-pin GPIO header fits Raspberry Pi boards
  • MC33886 H-bridge drives DC motors forward and reverse
  • Onboard 5V regulator powers the Raspberry Pi up to 2A
  • Built-in IR receiver enables remote robot control
  • 7V–40V input with 2A self-recovery fuse protects the Pi

Motor Driver Board for Raspberry Pi

The LORDWORLD expansion board adds dual-direction DC motor control to any Raspberry Pi model equipped with a 40PIN GPIO header. It targets hobbyists building mobile robots or remote-controlled vehicles who need a single-board driver solution. The onboard Freescale MC33886 H-bridge handles the motor-driving task while the board also supplies regulated power to the Pi itself.

Thermals and Power Characteristics

A multi-protection circuit and a 2A self-recovery fuse guard the host board against over-current events. The driver chip includes short-circuit shutdown and undervoltage disable functions, while reversed polarity protection covers the motor outputs and an anti-reverse diode protects the power input. The module accepts a wide 7V to 40V supply and can deliver up to 5A to a single motor.

Bundled Features and Their Impact

An integrated 5V regulator powers the Raspberry Pi at up to 2A, removing the need for a separate supply in many builds. The onboard IR receiver enables direct infrared remote control without extra wiring or external modules. Together these functions reduce part count and simplify the electronics stack for DIY robotics projects.

Perguntas sobre este artigo

How do I install the board onto the Raspberry Pi and what step is often missed?

Align the 40PIN GPIO extension header with the Pi's header and press down evenly; the step often missed is confirming the 7V–40V power supply is connected to the board's input terminals before powering the Pi via the onboard 5V regulator.

What maintenance or replacement will the board need later?

The 2A self-recovery fuse resets automatically after an over-current event; no user replacement is required unless the fuse or the MC33886 driver chip suffers permanent damage from sustained overloads beyond the 5A per motor limit.

What limit appears first during sustained high-load operation?

The single motor output current limit of up to 5A is reached first; the MC33886 then triggers its short-circuit shutdown and undervoltage disable functions to protect the driver and the Pi.
