Bottom line: The USB Slave SPI Breakout Board is a niche pick — read recent reviews before buying in the emulation hardware category, priced around $15.99. Read recent reviews carefully before committing.
The USB SPI Slave Breakout Board provides a simple interface for bi-directional communication with the PC from any MCU (including the AVR family). It is designed to connect directly to the standard bread board with a reduced footprint. Once connected to an MCU, the MCU Master SPI bus connects to the FT220X chip. This chip connects the SPI bus to the USB bus.Hardware Features:USB 2.0 Hi-Speed (480Mb/s)Independent USB to SPI Slave Bus Running 12MHz Max Clock SpeedBoard is used as COM Port on the PCUSB PoweredProvides external +3.3volts @ 50mAFT220X FTDI chip has on chip 512 byte Receive and…

Key Features
- USB Slave SPI Breakout Board Transfer data directly to the PC from any MCU. This product comes complete with sample software for both the MCU and the PC.
- Slave SPI bus runs at up to 12 MHz. Sample code allows up to eight individual channels (such as analog data) to be displayed on the PC at one time.
- Easy to use software. The PC communicates with the USB SPI Slave Breakout Board as COM Port. This allows any simple Terminal Window software (such as TeraTerm) to communicate directly with the MCU.
- Provides power for external MCU. This board has a +3.3V @ 50mA power output. Enough power for most AVR MCU's.
- Connects to standard Bread Board with reduced footprint. The board features surface mounted 0.1 inch headers on the bottom of the board. This allows the board to take up less real estate on the Bread Board and leaves more room for connections.
