Transfer SPI data directly to the PC

The USB SPI Slave Breakout Board provides a simple interface for bi-directional communication with the PC from any MCU (including the Arduino 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. 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.

Earth People provides sample software so the user can use the Arduino functions to send data to be graphed on the PC.

Hardware Features:

• USB 2.0 Full Speed
• Independent USB to SPI Slave Bus Running 12MHz Max Clock Speed
• Board is used as COM Port on the PC
• USB Powered
• Provides external +3.3volts @ 50mA
• FT220X FTDI chip has on chip 512 byte Receive and Transmit Buffers
• Compatible with any external +5/3.3 Volt MCU (Including all Arduinos)

Description

The USB SPI Slave Breakout Board consists of the FT220X chip from FTDI. This single chip solution connects the Slave SPI bus directly to USB. The board includes a USB Micro B connector and two 1x8 0.1 inch headers. The board is powered from the USB port of the PC. It provides +3.3V regulated output to power up user MCU’s or any other power need. Current from the +3.3V regulated output is 50mA. No external power is needed for the USB SPI Slave Breakout Board.

High Speed Data Display

The USB SPI Slave Breakout Board comes with example software that displays data from the External MCU (Such as the Arduino Mini Pro). The user can display multiple channels of data analog, temperature sensor or digitally generated data.
