As a professional distributor with nearly three decades of expertise in electronic components, Shenzhen Mingjiada Electronics Co., Ltd. now offers globally available, brand-new, in-stock units of three core products from the u-blox MAYA-W3 series: MAYA-W381-00B, MAYA-W383-00B, and MAYA-W386-00B. Additionally, to assist customers in optimizing inventory management, we offer long-term, high-value buyback services for popular general-purpose models such as the MAYA-W383-00B and MAYA-W386-00B.
Based on the Infineon AIROC™ CYW55513 chipset, these modules support tri-band Wi-Fi 6/6E and BT 5.4 dual-mode concurrent operation. Packaged in a compact 10.4×14.3mm LGA form factor, they deliver secure, low-power, high-data-rate wireless connectivity solutions for industrial IoT, smart buildings, medical devices, and other applications.
Product Series Overview
The u-blox MAYA-W3 series are host-based multi-radio modules designed, manufactured, and tested to meet industrial-grade reliability and quality requirements. These modules support SISO Wi-Fi 6/6E operation, significantly enhancing network availability in dense Wi-Fi environments, and feature MU-MIMO technology. The module can function as an access point (AP), station (STA), Wi-Fi Direct (P2P), or a combination of these roles.
For BT, the MAYA-W3 series supports BT 6.0 dual-mode (Classic BT + BT Low Energy), including synchronous channels for LE Audio, providing a robust foundation for next-generation wireless audio applications.
