NL6621 Wifi Module

Description

Features:

• IC feature page.
• Main features: Wifi embedded + 160Mhz ARM M3 + 448KB RAM, rich interface and great extensive capability
• Run UC-OS II system
• NL6621M is a SOC of high integration, dedicated to wireless LAN products of high data throughput and low cost. It integrates MCU，MAC，1T1R baseband and RF transceiver with amplifier onto one chip.
• NL6621M supports 802.11b/ g n and Wi-Fi direct（SDIO network card mode），BSS STA，soft AP，WiFi protection setup. Also it supports WMM-PS and WPA/ WPA2 security protocol.
• NL6621M can serve as slave controlled by main processor, or independent WLAN device needing no other processors.
• The general purpose interfaces it supported include QuadSPI，standard SPI，I2C，UART，GPIO，I2S audio and PWM audio.
• NL6621M can be directly connected to plentiful peripheral equipment such as sound box，pick-up head，flash memory and LCD, etc. Plentiful internet protocols such as TCP/ IP, UPD and HTTP, etc. have been integrated to nl6621m. With high-performance transmission over radio, plentiful interfaces and protocols,
• NL6621M is a best choice for monolithic chip solution such as wireless audio, wireless video, wireless wisdom household and wireless medical treatment, etc.
• Secondary development: Complete open source, Standar_SDK，Wifi-Uart_SDK，Apple Homekit_SDK，Gizwits_SDK (mostly in Chinese for now)
• SDK mostly in C, and complied in Keil.
• Default firmware is AT commands
