MICROCHIP EV48R50A Graphics Prototype Board for Curiosity Boards
Detailed Product Information
The EV48R50A Graphics Prototyping Board for Curiosity enables developers and customers to integrate and prototype their display modules with 32-bit MCU Graphics development boards. The board has a compatible interface for the display connector on both the SAM and PIC32 development boards. It comes with multiple footprints for flat cable connectors to connect display modules. The board allows for the flexible mapping of display signals from the development board to the display module connectors. Display boards that support dual-edge female 67POS 0.020 connectors may be used with the prototyping board.
Product Usage Instructions
Users can utilize the LED driver and bare component pad circuits to test functionalities, such as backlight displays. Here are the instructions on how to use the Graphics Prototyping Board:
Connecting Graphics Connector to MCU Board
To connect the graphics connector to the MCU board, follow these steps:
- Locate the J1 connector on the Graphics Prototyping Board.
- Connect the graphics connector from the target MCU board to J1 connector on the Graphics Prototyping Board.
Prototyping Area
The prototyping area consists of bare component pads. Users can use these pads to connect various components and test functionalities.
Using LED Driver Circuit
The LED driver circuit is used to test the backlight display. To use this circuit, follow these steps:
- Locate the LED driver circuit on the Graphics Prototyping Board.
- Connect the display board to the corresponding connector on the Graphics Prototyping Board. The board accommodates display modules with different cables and interfaces, such as RGB and parallel 8080, as well as the interface to a touchscreen controller.
- Apply power to the MCU board.
- The LEDs will light up, indicating that the backlight display is working.

Introduction
The Graphics Prototype Board for Curiosity (EV48R50A) with its graphics connector, 6 LCD connectors, LED driver and bare component pads, enables the user to perform these actions:
- Prototype an off-the-shelf display (RGB, parallel 8080, and so on) to an MCU Graphics development board
- Prototype other color modes, such as RGB332 or other interfaces
- Probe display and touch signals for debugging
- Prototype touch controllers and other touch interfaces
- Connect to the Curiosity Pro or Ultra Graphics Port Standard interface
Overview
The Graphics Prototype Board has a compatible interface for the display connector on both the SAM and PIC32 development boards. It comes with multiple footprints for flat cable connectors to connect display modules. The board allows for the flexible mapping of display signals from the development board to the display module connectors. Display boards which support a dual edge female 67POS 0.020 connector may be used with the prototyping board.
Graphics Connector
The graphics connector provides an interface between the MCU board and the
graphics display. It adds the ability to change the wired interface by
providing an accessible jumper wire end point when connecting displays of
different types to the same MCU board.

LCD Connectors
The graphics prototype board comes with footprints for LCD connectors of
different pitch and positions. This can accommodate display modules with
different cables and interfaces, such as RGB and parallel 8080 as well as the
interface to a touch screen controller.

| 6 | J10 | 0.5 | 6 |
Bare Component Pads
The bare component pads further extend the capabilities of the board, allowing
the addition of more functionality to the design including prototyping touch
interfaces, probing displays, and touch signals for debugging. The user can
add features to the design, such as the addition of different sensor types.
