FAQ'S

What is the wholesale price of the MT8870 DTMF Voice Decoding Module in India?

The wholesale price of the MT8870 DTMF Voice Decoding Module 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.

What is the MOQ for bulk MT8870 DTMF Voice Decoding Module orders?

The minimum order quantity (MOQ) for bulk MT8870 DTMF Voice Decoding Module is 500 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 500 units, we can also arrange customized pricing and delivery schedules based on your project, OEM production, or institutional needs.

Do you provide GST invoices?

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.

Is the MT8870 DTMF Voice Decoding Module compatible with Arduino and Raspberry Pi?

Yes, the MT8870 DTMF Voice Decoding Module is fully compatible with Arduino, Raspberry Pi, ESP32, and most microcontroller platforms. It decodes telephone keypad tones into 4-bit digital outputs, allowing your microcontroller to easily interpret remote commands. This makes it ideal for telephony-based control systems, GSM remote switching, access control, robotics, wireless automation, and other projects requiring DTMF signal processing. The module requires only simple wiring and provides stable, reliable tone detection for both beginners and advanced embedded developers.

Do you offer warranty on bulk purchases?

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.
