XR-53B Offine voice+WiFi

Xr-53b is a WiFi + speech recognition module composed of xr808ct2 WiFi chip and jx108 voice chip. The core processor xr808ct2 integrates arm cortex-m4f 32-bit microcontroller in a small size, and supports the master clock frequency from 32kHz to 160MHz. It also integrates high-performance WLAN system, including Wi Fi MAC / BB / RF / PA / LNA Unit; integrates large on-chip memory and rich peripheral resources to facilitate users to develop IOT applications; supports single wheat high-precision offline speech recognition, and can quickly customize wake-up words and command words; on-board 3W audio power amplifier; xr-53b module supports standard ieee802.11b/g/n protocol, supports RTOS, and has a complete TCP / IP protocol stack, which users can use The module develops voice recognition application with networking function for existing equipment, and can also be used as the main controller to design wireless network products. It can be quickly applied to smart home, all kinds of intelligent small appliances, 86 boxes, toys, lamps and other products that need voice control.
