The wholesale price of the 1 channel 5V active low relay module depends on the order quantity, but bulk buyers can get up to 30% off compared to retail rates. Larger quantities always get better pricing because packaging, shipping, and handling costs reduce per unit. If you're planning a bulk project or stocking up for resale, the wholesale option gives you the best overall value.

The minimum order quantity (MOQ) for bulk relay module is 500 units. This MOQ helps us provide stable pricing, ensure quality testing for every batch, and offer faster dispatch times. If you need more than 500 units, we can also prepare custom pricing and lead times depending on your project requirements.

Yes, the 1-Channel 5V Active Low Relay Module is fully compatible with both Arduino and Raspberry Pi. It can be controlled directly using digital output pins—Arduino boards can use standard HIGH/LOW signals, while Raspberry Pi can use GPIO pins with proper voltage level considerations. These modules are widely used in home automation, IoT, robotics, and embedded electronics projects to switch high-voltage AC or DC devices with microcontrollers safely. Sample wiring diagrams and code libraries are also available for easy integration.
