Memory Socket on standard V6.1 screen?
¿ªÔÆÌåÓýHere is something I never noticed before. The standard V6.1, 2.8 IN. screen has a memory socket similar to Nextion 2.8 screen. Can the standard screen hold a more elaborate program similar to the nextion family of screens? If so, where can I find the programming parameters? ? ? ? Jamey KS 0Z JN |

As one can see from the picture, the SD card socket is not connected to anything.
It's there because the original design it's cloned from had one and it has stayed. It does allow having images and other stuff on an SD card if using some small microcontroller like most arduinos. But I, doubt there's any space left in the arduino used in uBITX for the filesystem and other stuff to make any use of it. |

¿ªÔÆÌåÓýThank you. ? Yes, I have read from VU2ESE that the there is no more room on the Arduino. I found a pretty reasonable priced Nextion 2.8¡± (for USA, anyway) at RobotShop.com . ?
Tax and shipping are in that total. ? Their price without tax and shipping is: US $25.40. ? Jamey KS0ZJN ? From: [email protected] <[email protected]>

Jamey: I have been buying displays from BuyDisplay.com for several years now. They have good prices (i.e., a 2.8" TFT display is under $18) and reasonably fast shipping. We are using their 5" display: which is an 800x480 display with great fidelity with SPI interface for about $48. While I think the smallest display I've ordered from them was a 3.5", my guess is their 2.8" would be a good substitute for yours at about half the price. True, you will have to wait a couple of weeks, but depending upon where you are in your project, that might not be an issue. Jack, W8TEE

It looks like that SD card socket is only there for convenience in an embedded system. The traces are just connected to those labelled holes. On Fri, Mar 11, 2022 at 3:05 AM KS0ZJN <star-guy@...> wrote:
