4. Requirements
The uEZGUI-EXP-DK comes with the necessary flex cables to begin development right away with the purchase of a
compatible uEZGUI kit. A 7V-24V power supply with a minimum of 1A current will be required to power the
uEZGUI-EXP-DK and connected uEZGUI. At this time, the uEZGUI-EXP-DK’s expansion pin configuration is compatible
with uEZGUIs based on the following microcontrollers:
•
NXP LPC1788 (part numbers starting with uEZGUI-1788)
•
NXP LPC2478 (part numbers starting with uEZGUI-2478)
•
Renesas RX62N (part numbers starting with uEZGUI-RX62N)
With the 70 pin break-out and the ability to cut PCB traces, the uEZGUI-EXP-DK could be re-configured to support future
uEZGUIs, or to swap for the desired pins on existing uEZGUIs. Note that some features of the uEZGUI-EXP-DK will only
work with certain microcontrollers, such as the 4-bit microSD card slot and I2S audio.
