1 INTRODUCTION

The Oolite V3.1 motherboard pick up Oolite V3.1 module .The Oolite V3.1 module use the MT7688AN chipset. The MT7688AN 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. The MT7688AN provides two operation modes C 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 the MT7688AN to add 3G/LTE modem support or add a H.264 ISP for wireless IP camera. For the IoT device mode, the MT7688AN supports eMMC, SD-XC and USB 2.0. The MT7688AN 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.

storage condition

The calculated shelf life in a sealed bag is 12 months if stored between 0 <C and 40 <C at less than 90% relative humidity (RH). After the bag is opened, devices that are subjected to solder reflow or other high temperature processes must be handled in the following manner:

 Mounted within 168 hours of factory conditions, i.e. < 30 C at 60% RH.

 Storage humidity needs to maintained at < 10% RH.

 Baking is necessary if the customer exposes the component to air for over 168 hrs, baking conditions: 125 <C for 8 hrs.

8 INSTALLED MATTERS NEEDING ATTENTION (FOR WIFI MODULE)

a. In the opening of the steel mesh, the module of the pad hole in a ratio of 1:1 to expand 0.7mm and thickness of 0.12 mm.

b. Putting the module to the oven at 120  (\5) baking for 12 hours, and then on the basis of how much per hour can stick taking out the corresponding number of modules.

c. Bring gloves and electrostatic ring to get the module.

d. The furnace temperature on the basis of main board size .
