Mingjiada Electronics: Supplying Espressif ESP32-C61-MINI-1 and ESP32-C61-MINI-1U Modules to Usher in a New Era of Wi-Fi 6 IoT; Simultaneously Offering High-Priced Buyback for Inventory in This Series
May 19, 2026
As IoT devices rapidly evolve toward high concurrency, low latency, and low power consumption, Wi-Fi 6 technology has become a critical requirement in the smart home, industrial automation, and healthcare sectors. As an industry-leading electronic component supply chain service provider, Shenzhen Mingjiada Electronics Co., Ltd. stays at the forefront of technology and is pleased to announce the availability of large quantities of two core modules from Espressif Systems: the ESP32-C61-MINI-1 and ESP32-C61-MINI-1U.
At the same time, to help customers optimize their inventory structure and revitalize idle assets, Mingjiada Electronics is launching a “High-Priced Buyback” service globally, specifically targeting the ESP32-C61 series, C6 series, and the entire ESP32 series of obsolete inventory.
Core Product Overview: Designed for High-Efficiency IoT
As Espressif’s Wi-Fi 6 + Bluetooth 5 (LE) combo module, the ESP32-C61 series features a RISC-V 32-bit single-core processor with a clock speed of up to 160 MHz. It is designed to meet the performance demands of next-generation IoT devices with higher integration and energy efficiency.
The two models highlighted by Mingjiada Electronics in this supply are complementary in both form factor and functionality. Specific specifications are as follows:
1. ESP32-C61-MINI-1 (On-Board Antenna Version)
Product Positioning: Ultra-compact solution.
Key Parameters:
Dimensions: 13.2 mm × 16.6 mm × 2.4 mm.
Antenna Type: On-board PCB antenna, suitable for devices that do not require complex antenna designs and have limited installation space.
Memory Configuration: Supports up to 8 MB of Flash and 8 MB of PSRAM (as in the N8R8 model).
Applications: Smart lighting, smart plugs, and simple sensor gateways.
2. ESP32-C61-MINI-1U (IPEX External Antenna Version)
Product Positioning: Strong signal and high-reliability connectivity.
Key Parameters:
Package Dimensions: 13.2 mm × 12.5 mm × 2.4 mm (more compact than the MINI-1).
Antenna Type: Connects to an external antenna via a U.FL interface.
Key Advantages: Users can flexibly select high-gain antennas to overcome signal shielding caused by complex environments such as metal enclosures, providing longer transmission distances and more stable wall-penetration capabilities.
Applications: Industrial automation data acquisition, outdoor IoT devices, and consumer electronics requiring complex antenna layouts.
Technical Highlights: More Than Just Connectivity
The ESP32-C61-MINI series modules not only support traditional 802.11b/g/n standards but also fully support 802.11ax (Wi-Fi 6) features, delivering a significant performance leap for users:
High Efficiency and Low Latency: Supports OFDMA and MU-MIMO technologies, significantly reducing latency during concurrent multi-device connections, making it particularly suitable for whole-home smart home scenarios.
Longer Standby Time: The introduction of the Target Wake Time (TWT) mechanism greatly optimizes device sleep scheduling, significantly extending battery life for battery-powered sensor devices.
Enhanced Bluetooth Performance: Certified for Bluetooth 5.3, it supports LE Audio and Mesh networking, providing a data rate range of 125 Kbps to 2 Mbps for location services and beacon applications.
Mingjiada Electronics’ Two-Way Service: Integrated Supply and Recycling
Against the backdrop of current semiconductor supply chain volatility, Mingjiada Electronics has launched a “Long-Term Supply + High-Value Recycling” two-way service model to alleviate supply chain pressures for customers caused by production capacity miscalculations or project changes.
1. Mingjiada Genuine Stock Supply
As one of Espressif’s distribution channels, Mingjiada Electronics maintains ample inventory and supports both sample requests and bulk shipments:
Available Models: ESP32-C61-MINI-1-N4 (4MB Flash), ESP32-C61-MINI-1U-N8R8 (8MB Flash + 8MB PSRAM), and other high-spec versions.
Service Commitment: All products are genuine and authentic; inventory information is updated in real time; we support fast global shipping.
2. High-Priced Buyback/Recycling: Channel for Liquidating Inventory
For customers with idle inventory resulting from project iterations (such as upgrading from the Mini solution to the WROOM solution) or order cancellations, Mingjiada is now offering high-priced buyback services globally:
Models Accepted: ESP32-C61-MINI-1 (all suffixes, including N4/N8, etc.), ESP32-C61-MINI-1U (including U.FL versions).
Scope of Buyback: We also offer long-term buyback services for the full range of Espressif (Eraspice) C3, C6, S3, and P4 series, as well as the high-end ESP32-S3 series inventory.
Benefits of Recycling: Cash transactions, protection of customer business privacy, and conversion of idle inventory into working capital.
