NL6621-Y1 2.4G Uart Serial Wi-Fi Transceiver Module for Arduino
This is a serial Wi-Fi module based on NL6621M. It is TTL serial communication interface and its parameters can be set by AT command. - Working frequency: 2.4GHz - Wireless criteria: 802.11 b / g / n - Wireless Network Mode: station / softAP / SoftAP + station - Working voltage: 3.3V - Working current: 200mA(MAX) - Sleep current: 3.7mA - Onboard ports: UART TTL£¬ which can be used as control interface or GPIO. I2C£¬ which can externally connect to EEPROM storage chip. - Serial port baud rate: 115200 (default)£¬ can be modified to other values ?by AT command - Serial communication format: 8N1 - Antenna: Built-in PCB antenna - Great for DIY 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 both serve as slave controlled by main processor and 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 tools: Complete open source SDK such as Standar_SDK£¬ Wifi-Uart_SDK£¬ Apple Homekit_SDK£¬ Gizwits_SDK CPU on the chip: - The basic frequency can be configured as£º 160M£¬120M£¬80M£¬40M£» - 448KB RAM£¨CODE RAM is 192K£©can be used by WLAN and custom-built applications Application area:Smart security guard£¬ Internet household appliances£¬ Smart toys£¬ Wi-Fi lamp£¬ Smart card terminal£¬ Wi-Fi sound box
