Olimex LCD-DRIVER Revision D Schematic and BOM
Hardware design and BOM for Olimex LCD-DRIVER Rev D, supporting 4.3" to 10.1" LCDs with Microchip AR1021T touch controller and AP3031 WLED backlight driver.
Overview
This electronics design document provides the schematic and bill of materials for the Olimex LCD-DRIVER Revision D. The board is a versatile interface designed to drive LCD panels ranging from 4.3 to 10.1 inches. It features a Microchip AR1021T-I/SS resistive touch screen controller, a Microchip AT24C16C-SSHM-T EEPROM for configuration data, and a Diodes Incorporated AP3031KTR-G1 step-up DC-DC converter for WLED backlight driving. The design includes multiple connector footprints to ensure compatibility with various display manufacturers such as BOE, Innolux (AT070TN92), and GFT. Power management is supported by Infineon IRLML6402 MOSFETs and Rohm DTC114YKA transistors, accommodating both 3.3V and 5V logic levels.
Use Cases
- Interfacing 4.3-inch to 10.1-inch LCD panels with development boards
- Implementing resistive or capacitive touch screen control in embedded systems
- Backlight power management for multi-size IPS and TFT displays
- Customizing display interfaces for OLinuXino hardware
