第一版

MediaTek 

LinkIt One負責對IoT DB通訊,及氣溫、光照與魚缸水位四項主要任務
Wrtnode負責產生即時影像
 
此外還結合通訊功能在緊急高水溫情況下發出簡訊給飼主給予警訊(這個目前的版本還沒有)
MediaTek MT76888 Duo
 
MT7688 family integrates a 1T1R 802.11n Wi-Fi radio, a 575/580MHz 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 a 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.

LinkIt ONE

 

The LinkIt ONE development board is an open source, high performance board for prototyping Wearables and IoT devices. It's based on the world's leading SoC for Wearables, MediaTek Aster (MT2502) combined with high performance Wi-Fi (MT5931) and GPS (MT3332) chipsets to provide you with access to all the features of MediaTek LinkIt. It also provides similar pin-out features to Arduino boards, making it easy for you to connect to various sensors, peripherals, and Arduino shields.

It also provides similar pin-out features to Arduino boards, making it easy for you to connect to various sensors, peripherals, and Groves.

LinkIt ONE is a co-design product by Seeed Studio and MediaTek. It brings together the parties' knowledge in open hardware and industry leading reference designs for Wearables and IoT devices to create this powerful development board.

LinkIt ONE development is fully supported on the MediaTek Labs site: check out the LinkIt section and register here to download the SDK, participate in the Forums, and more.
