Exact DC-10121 route. The seller title calls it inbuilt Arduino, while the exact description identifies its onboard ATMEGA328P-AU MCU. Do not merge it with EC200U-CN nano, STM32 or ESP32 variants. Conflicting stock signals are intentionally preserved as unknown; verify India carrier compatibility and compliance for the intended SIM deployment.

7Semi EC200U LTE 4G GNSS IoT Smart Modem with inbuilt Arduino | EveltaEvelta's exact page identifies SKU 004-DC-10121 and MPN DC-10121 as the EC200U GNSS smart modem with an onboard ATMEGA328P-AU MCU. It displays INR 2,979.50 including GST (INR 2,525 excluding GST), a GST Invoice signal, 24-hour Mumbai-warehouse dispatch and a 14-day manufacturing-defect replacement term; the page simultaneously renders In Stock and Sold Out, so availability is not asserted.

Ordered by human-assigned verification status, then seller name.

Product-specific buyer note

Evelta adds an exact DC-10121 EC200U GNSS smart-modem route at INR 2,979.50 including GST, with GST-invoice and 24-hour Mumbai-warehouse dispatch wording but contradictory stock states. Match the onboard ATMEGA328P-AU, not EC200U-CN nano, STM32 or ESP32 variants. Confirm allocation, board revision, antennas, peak-current supply, carrier/SIM compatibility, invoice, replacement scope, shipping and warranty terms before ordering.

India regulatory note

Radio hardware uses licensed cellular spectrum through a SIM. This listing does not prove Indian carrier certification, IMEI/TAC acceptance, WPC/TEC/MTCTE status, or service provisioning. Verify the exact modem SKU, supported bands with the intended Indian operator, APN/SIM plan, importer compliance documents, and GST invoice before deployment.
