Marvell 88PA6120 3D Printer Development Kit
Enabling full featured consumer 3D printers
PRODUCT OVERVIEW
The Marvell® 3D printer development kit is a complete hardware and software platform to support the design of production
ready 3D printer systems built around the 88PA6120 system on a chip. The comprehensive hardware development platform
has support for multiple print mechanisms and technologies as well as a robust set of user interfaces enabling system vendors
to evaluate many possible solutions. The hardware development kit contains schematics, board layout files and bill of materials
to enable engineers to quickly modify the electronics to fit the individual needs of the 3D printer in design. Full Linux-based SDK
enables 3D printing functionality as well as robust volume proven user interfaces and network connectivity with all source code
reducing the customer development effort and time to market.
At the core of the reference platform is the Marvell 88PA6120 which integrates a powerful 533MHz ARM v7 compatible processor
to handle all the application processing requirements. The 88PA6120 augments the main processor with a direct engine control
interface supporting highly integrated real time motion control of 3D print mechanisms and print output thereby reducing overall
system cost.
The 88PA6120 integrates many system interfaces including a USB 2.0 device, USB 2.0 host and a dual mode USB 2.0 interface,
a complete 10/100 (Fast Ethernet) solution with integrated PHY, and dual SDIO interfaces for memory card and Marvell Wi-Fi
solutions. In addition 88PA6120 integrates support for a number of different serial peripheral interfaces including SPI, 16550compatible UARTs, and I2C for Bluetooth. User interfaces are supported by an integrated LCD controller and multiple GPIO.
