💡 New to electronics? Pair this with an Arduino starter kit for a complete learning experience.

🔹 HW-131 Power Module Instructions (Important!)

⚠️ Common Mistakes to Avoid:

🔹Do not use a 5V adapter on the DC jack – the module won't output 5V

🔹If you only need 3.3V, the 5V output will also provide stable 3.3V

🔹For loads near 700mA, ensure adequate cooling and stable power supply

🔹Do not exceed input voltage range (6.5-12V) to avoid damaging the regulator

🔹 Breadboard Usage Guide

1. Connection Rules：Metal clips connect horizontally in groups of 5. Red/blue lines indicate power rails:

🔹Red: Positive (+)

🔹Blue: Negative (-)

2. Mounting：Adhesive backing allows you to stick the board to a surface.

3. Expansion：Multiple boards can be snapped together via side connectors.

4. Wire Gauge：Compatible with AWG 20-29 (our jumper wires work perfectly).

🔹 Specifications

🔹 Common Questions

❓ 400-point vs 830-point breadboard – which to choose?

🔹400-point: Compact, great for small projects and sensor testing.

🔹830-point: More space for complex circuits, can mount the power module directly.

🔹Choose based on your project size, or combine multiple boards.

❓ Why doesn't the HW-131 power module work with just USB?

The regulator requires about 1.5V higher input than output. USB provides 5V, which is not enough for stable 5V output. Use a 6.5-12V DC adapter, or use only the 3.3V output (the 5V output will also provide 3.3V).

❓ Does the power module snap into the breadboard?

Yes, it fits perfectly into the 830-point (MB-102) breadboard power rail. For the 400-point board, you'll need jumper wires to connect it.

❓ Are the jumper wires male-to-male or female-to-female?

This kit includes male-to-male jumper wires (pins on both ends), ideal for breadboard and Arduino pin connections.

❓ Can breadboards be reused?

Yes. The metal spring clips are durable for thousands of insertions, perfect for repeated prototyping.

❓ Is there packaging included?

This kit comes in simple packaging. Single items are not individually bagged; combo kits are packed together securely for shipping.

❓ Can both output channels be used at different voltages simultaneously?

Yes. The HW-131 module has two independent output channels. You can set one to 3.3V and the other to 5V using the jumper caps, powering different components at the same time.
