🔹 Q: 2.4V vs 5V – which one suits my project?
Use 2.4V version for low-power battery-driven devices (longer runtime). Choose 5V version for USB power or fixed circuit-board systems – it delivers stronger load capacity and stable speed under regular loads.
🔹 Q: Do you provide samples before bulk order?
Yes. We offer standard samples for both voltage versions. Test the motor with your assembly before mass production. Sample lead time: 10–20 working days.
🔹 Q: Can I mix 2.4V and 5V motors in one order?
Absolutely. Mixed orders with different voltages and reduction ratios are welcome. Just specify your required configuration per unit.
