LoRa Gateway + LoRA Node Match up’
LoRa.AI is a smart control solution for air conditioner. Low power, wide range, intelligent infrared remote control scheme .LoRa.AI constitute by LoRa Gateway + LoRA Node. Gateway: MT7688AN + SX1276 (470 MHZ or 470 MHZ), Device: the STM32 + SX1276 (470 MHZ or 470 MHZ). provide cloud entry points, can use a mobile phone to remote control, setting. Node Power supply by lithium batteries(4000mAh), rechargeable, a charge can be used for 300 days.
MT7688AN family integrates a 1T1R 802.11n Wi-Fi radio, a 580MHz MIPS® 24KEc™ CPU, 1-port fast Ethernet PHY, USB2.0 host, PCIe, SD-XC, I2S/PCM and multiple slow IOs.
MT7688 provides two operation modes – IoT gateway mode and IoT device mode. In IoT gateway mode, the PCI Express interface can connect to 802.11ac.chipset for 11ac dual-band concurrent gateway. The high-performance USB 2.0 allows MT7688 to add 3G/LTE modem support or add an H.264 ISP for wireless IP camera. For the IoT device mode, MT7688 supports eMMC, SD-XC and USB 2.0. MT7688 can support the WiFi high-quality audio via 192Kbps/24bits I2S interface and VoIP application through PCM. In IoT device mode, it further supports PWM, SPI slave, 3rd UART and more GPIOs.For IoT gateway, it can connect to touch panel and BLE, Zigbee/Z-Wave and sub-1G RF for smart home control.
The SX1276 transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The SX1276 deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
