Description

The Squeak Board is a small PCB that adapts the Cuica's 20-Pin Interface, simplifying electrical integration with a DUT.

Programming Interfaces

• 20-Pin JTAG Port
• 20-Pin SWD Port

I/O Interfaces

• 4x GPIO Screw Terminals
• I2C 0.1" Pitch Header Pins
• I2C 1mm Pitch JST Connector
• UART 0.1" Pitch Header Pins
• UART 1mm Pitch JST Connector
• SPI 0.1" Pitch Header Pins
• SPI 1mm Pitch JST Connector

Additional Interfaces

Four low-power terminals are also provided:

• 2x GND Screw Terminal
• 3.3v Screw Terminal
• 5.0v Screw Terminal

There are also jumpers at J1, J2, J3, and J4, which can be used to allow the GPIO lines to be driven by the two on-board push-button switches or to control the two on-board LEDs for Test Script debugging.
