The Oolite V3.2D module uses the MT7628AN chipset. The MT7628AN includes a high-performance 580/575 MHz MIPS 24KEc CPU core and high-speed USB2.0/PCIe interfaces, which are 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.
