FAQ'S

What is the wholesale price of the Arduino Leonardo R3 compatible board in India?

The wholesale price of the Arduino Arduino Leonardo R3 compatible board varies depending on the order quantity, but bulk buyers generally receive significant discounts compared to retail rates. Larger quantities reduce per-unit cost because packaging, handling, and logistics are more efficient in bulk orders. If you’re purchasing for OEM production, school or college labs, DIY kit assembly, or resale, opting for wholesale pricing offers the best value for high-volume requirements.

The minimum order quantity (MOQ) for bulk Arduino Leonardo R3 compatible board is 50 units. This MOQ helps maintain stable pricing, ensures consistent batch-level quality checks, and allows faster dispatch for large orders. If you require more than 50 units, we can also arrange customized pricing and delivery schedules based on your project, OEM production, or institutional needs.

Yes, GST invoices are provided for all orders. Whether you're a retailer, institute, startup, or company, you will receive a proper GST bill that you can use for input tax credit and accounting purposes. Just provide your GST details during checkout or share them with the sales team.

We offer warranty only on branded products, and the coverage is based on the manufacturer’s policy. Generic products do not usually come with warranty, but branded products are covered as per their official guidelines. If you're ordering large quantities and want warranty-backed products, just let us know and we will recommend the best options.
