222Product description
The MAYA-W3 series host-based modules are designed,built, and tested to meet the high reliability and quality
requirements of a wide range of industrial applications, suchas smart manufacturing, tracking and telematics, building
automation, professional appliances, healthcare, and EV
charging infrastructures.
MAYA-W3 modules provide SISO Wi-Fi 6/6E operation with
20 MHz channel width, improved network availability in dense
Wi‑Fi environments, and MU-MIMO. The modules can workas access point, station, in P2P connections, or combinationsof these. MAYA-W3 supports Bluetooth Low Energy 5.4,
including the use of isochronous channels for LE Audio.
At 10.4 x 14.3 mm, MAYA-W3 are among the most compact
Wi‑Fi 6/6E SMD modules available in the market.
All u-blox modules undergo extensive qualification tests toensure reliability over their life-time, and each module is fully
tested before leaving the assembly line.
The MAYA-W3 series is based on the CYW5551/2/3 chips
from Infineon.
