Wire an external battery pack or power supply (e.g., a 2S LiPo or 4 x AA battery holder) to the EXT_PWR terminals [1]. Ensure correct polarity (+ to +, - to -).
Since the "HW-130" is a very common, generic motor driver shield (often based on the L298P chip) typically manufactured by generic Chinese brands like HW, Keyes, or RobotDyn, there is no single official "corporate" datasheet like you would find for an Intel processor.
Digital pins 2 and 13, and all Analog pins (A0-A5), are typically left unused and can be used for sensors. 🔋 Power Management There are two main ways to power your setup: hw 130 motor control shield for arduino datasheet free
: Two L293D dual H-bridge motor drivers and one 74HC595 shift register. Output Channels 4 bi-directional DC motors with individual 8-bit speed selection. 2 stepper motors (unipolar or bipolar). 2 dedicated headers
Plug your servo motor into the SER1 or SER2 3-pin slots [1]. Ensure the ground wire (black or brown) aligns with the minus (-) marking on the board. Wire an external battery pack or power supply (e

The official Arduino forum and many regional forums contain threads about the HW‑130. These threads often include troubleshooting guides, alternative wiring diagrams, and user‑shared code that can serve as a practical datasheet. Notable examples include: Digital pins 2 and 13, and all Analog
: Achieved through 8-bit PWM (Pulse Width Modulation), allowing for 0.5% resolution speed adjustments. Accessibility
