beaglebone black tft lcd factory

The BeagleBone LCD7 Cape provides an LCD solution with touchscreen capability for BeagleBone boards. The 7" TFT LCD screen, attached to the topside of the board, can display up to a resolution of 800x480 and is a 4-wire resistive touchscreen. The board is equipped with seven buttons located at finger-friendly positions. These buttons include power, reset, and five user buttons, which are mapped to different GPIO signals. The backside of the cape is where the BeagleBone and additional cape can be mounted.

In revision A3 the Enter button has been moved from GPIO3_19 to GPIO0_3 and LCD_DVDD_EN has moved from GPIO1_31 to GPIO0_2. These changes in GPIOs are to support awake interrupt in sleeping mode.

The latest revision A3 have 10 eMMC pins removed from the LCD7"s expansion connector. This removal is due to the fact that this LCD7 Cape was originally designed for the BeagleBone (White); thus, when using with BeagleBone Black, these eMMC signals are subjected to load and noises, creating problems with booting and using the eMMC.

We have been reported by a small number of users that their LCD7 Capes revision A3 have some issues with BeagleBone Black. These issues could be hanging during boot or crashing when accessing Angstrom system menu. The LCD7 Cape was originally designed for BeagleBone (White), which boots from SD card. When using with BeagleBone Black and booting from eMMC, the integrity of eMMC signals on some LCD7 Cape may be affected. If your LCD7 Cape have this issue, there are three work-arounds below:

Cut 10 eMMC pins on connector J1 of your LCD7 Cape: 3-6, 20-25. You can visit this link for which pins are eMMC signals. The photo on the right shows J1 connector after the eMMC pins are removed.

Instead of permanently removing the eMMC pins on your LCD7 Cape, you can also use one of these Cape expansion connectors between the BeagleBone Black and LCD7 Cape. By using this connector, you can remove its eMMCs instead of the ones on LCD7 Cape. The photo on the right shows the Cape expansion connector is used and its eMMC pins are removed instead of the ones on LCD7 Cape.

Compatible with BeagleBone Black using Angstrom release 2013-06-20 onward. However, only booting from SD card is supported. Note: Using Angstrom release earlier than 2013-06-20 on BeagleBone Black and LCD7 may DAMAGE your BeagleBone Black. Ensure you are using 2013-06-20 or later.

Compatible with BeagleBone Black using Angstrom release 2013-06-20 onward. Note: Using Angstrom release earlier than 2013-06-20 on BeagleBone Black and LCD7 may DAMAGE your BeagleBone Black. Ensure you are using 2013-06-20 or later.

Thanks to Louis McCarthy and Gary Mort for the instructions below. These instructions were tested on "Linux beaglebone 3.8.13 #1 SMP Tue Jun 18 02:11:09 EDT 2013 armv7l GNU/Linux" release of Angstrom .

If you want to connect via DSS, you"ll need to level-shift the VSYNC, HSYNC, DOTCLOCK and ENABLE pins, the 24 color pins, (R0-7, G0-7, B-07); those will be connected to the corresponding pins at the BeagleBone. And the CS, SDI, SDO and SCL pins for initialization; those would be connected to CS, MOSI, MISO and CLK of an SPI port. To initialize the display you"ll have to output the init sequence that the display manufacturer dictates (you"ll have to look at their website or ask them for it). You"ll also need to read the display spec for other requirements and mode programming pins, and for instructions on how to drive the backlight.

This 7" touchscreen cape creates a fully integrated system when combined with your BeagleBone Black. Provides full Angstrom support for easy BeagleBone prototyping and projects. A secondary set of header pins gives built-in stacking cape-ability.

Compact and competitively priced, ARM platforms like Raspberry Pi and Beaglebone Black are becoming more popular and widespread in usage. Despite ARM architectures new popularity, it is still difficult to realize a stable and secure ARM-based TFT display application – but, Apollo Displays has done it.

Announced in the end of October 2011, the BeagleBone is a barebone development board with a Sitara ARM Cortex-A8 processor running at 720 MHz, 256 MB of RAM, two 46-pin expansion connectors, on-chip Ethernet, a microSD slot, and a USB host port and multipurpose device port which includes low-level serial control and JTAG hardware debug connections, so no JTAG emulator is required. The BeagleBone was initially priced at US$89.

A number of BeagleBone "Capes" have recently been released. These capes are expansion boards which can be stacked onto the BeagleBone Board (up to four at one time). BeagleBone capes include but are not limited to:

Launched on April 23, 2013, at a price of $45. Among other differences, it increases RAM to 512 MB, it increases the processor clock to 1 GHz, and it adds HDMI and 2 GB of eMMC flash memory. The BeagleBone Black also ships with Linux kernel 3.8, upgraded from the original BeagleBone"s Linux kernel 3.2, allowing the BeagleBone Black to take advantage of Direct Rendering Manager (DRM).

BeagleBone Black Revision C (released in 2014) increased the size of the flash memory to 4 GB. This enables it to ship with Debian GNU/Linux installed. Previous revisions shipped with Ångström Linux.

Launched in September 2017, PocketBeagle offers identical computing performance to BeagleBone Black in a physical form factor that offers over 50% reduction in size and 75% reduction in weight, along with over 40% cheaper purchase price (December 2018 MSRP US$25 vs. US$45 for BeagleBone Black). The miniaturization was made possible by using the Octavo Systems OSD3358-SM that shrinks all major subsystems of the BeagleBone Black into a single ceramic package attached using ball grid array. The advantages of the miniaturization come at the cost of removal of all built-in connectors except for a single micro USB port, the removal of on-board eMMC flash storage, and a reduction of header pins from 92 down to 72 due to space constraints, meaning that most capes will either not work at all or need heavy modifications to work with PocketBeagle. Just as the BeagleBone Black"s printed circuit board (PCB) is cut to fit snugly in an Altoids mint tin, PocketBeagle"s PCB is cut to fit snugly in an Altoids Smalls mint tin. Recommended use cases for PocketBeagle include embedded devices where size and weight considerations are most critical, such as quadcopter drones and other miniaturized robotics, along with handheld gaming applications.

NHD-7.0CTP-CAPE-N | BeagleBone Black Cape with TFT Display | 7.0" Sunlight Readable LCD | Capacitive Touchscreen | EEPROM with On-Board Dip Switches | Developing with Android & Linux

Engineered in Elgin IL USA, we designed this BeagleBone Cape to be a perfect fit for our 7.0” TFT displays and upgraded it with the sunlight readable NHD-7.0-800480EF-ASXN#-CTP display model. With capacitive 5-point multi-touch functionality and 800x480 resolution screen, this cape works seamlessly while developing with operating systems like Android and Linux. It includes an on-board dip switch for configuring EEPROM and secondary headers for additional cape connections. In addition to the secondary cape slot, we added four 3.5mm mounting holes that are compatible with standard M3 screws, a reset button, write protection pins, PWM backlight control, and an LED power indicator. With this cape we’ve made it easy to take your design process from concept to reality. When paired with the BeagleBone Black board (sold separately by beagleboard.org) you’ll have everything you need to plug-in and start developing.
