1 INTRODUCTIONTheOolite V3.2 module canuse the MT7688AN chipset or MT7628AN chipset.

1.1 Oolite V3.2D

TheOolite V3.2D moduleuse the MT7628AN chipset.The MT7628AN includes a high performance 580/575 MHz MIPS 24KEc CPU core and high speed USB2.0/PCIe interfaces, which is designed to enable a multitude of high performance, cost-effective IEEE 802.11n applications with a MediaTek WiFi client card.There are several masters (MIPS 24KEc, USB, PCI Express, SDXC, FE) in the MT7628 SoC on a high performance,low latency Rbus. In addition, the MT7628 SoC supports lower speed peripherals such as UART Lite, GPIO, I2C and SPI via a low speed peripheral bus (Pbus). The DDR/DDR2 controller is the only bus slave on the Rbus. It includes an Advanced Memory Scheduler to arbitrate the requests from bus masters, enhancing the performance of memory access intensive tasks.

1.2 Oolite V3.2S

TheOolite V3.2S moduleuse 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–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.
