While the HW 130 does not have an official manufacturer datasheet, it complies with the . For engineering purposes, refer to: int ENA = 3; // PWM capable int
Screw terminals for connecting DC motors (M1, M2, M3, M4), stepper motors, and external power supply (EXT_PWR). : The HW‑130 (V1) occupies the hardware SPI
: The HW‑130 (V1) occupies the hardware SPI pins (11, 12, 13), so you cannot use an SD card shield simultaneously unless you bit‑bang a second SPI interface. The V2 version uses only I²C (SDA/SCL) and avoids this limitation.
The HW-130 is a beginner-friendly, cost-effective shield based on the standard L298P driver chip. While the hardware is robust for small projects, the documentation (datasheet) often lacks clarity regarding pin mappings and power limits. Below is a breakdown of what the datasheet tells you—and what it often leaves out.
