Quote from: Rudolph on July 08, 2025, 06:23:04 PMBoth the NHD-7.0-800480AF-LSXP-CTP and the RVT70HSLNWC00 should work.

Adapting either of these to the VM820C is a bit of a challenge though.
The 30-position 2mm header CN2 on the VM820C has no pins for the backlight-LEDs.
And the pins for the backlight-controller on the VM820C are only connected to CN4.

The 45-postion FFC header CN4 is not compatible with the display connectors and is missing a couple of signals, so you need an adapter board to connect to either of these.

Connecting to the NHD-7.0-800480AF-LSXP-CTP might be a bit easier as it does not require VGL and VGH signals, but the RVT70HSLNWC00 does.

Both display have a 40pin FFC connector and the pinout is almost the same.
The NHD-7.0-800480AF-LSXP-CTP however deviates a little from one of the de-facto standard pinouts and has LED-K on pins 36/37 instead of 31/32.

The RVT70HSLNWC00 could be connected to a PCB800182 LCD adapter which I also used to connected my 1024x600 7" to, I reverse-engineered these adapters here: https://github.com/RudolphRiedel/PCB800182_LCD_Adapter
See above in this thread, I ended up not using the backlight-controller on the VM820C.

Now for the touch controller, both should work with the BT820, logically.
However, the NHD-7.0-800480AF-LSXP-CTP is using a 6-pin FFC that is not compatible with CN9 on the VM820C.
And RVT70HSLNWC00 uses a 10-pin FFC.
-> you need adapter boards to connect to either CN9 on the VM820C, or, what I found easier to do, connect to CN8 on the VM820C with wires using a cheap generic FFC breakout board on the display side.


Yeah, I wonder what the holdup is, I would be in the market for a fully integrated BT820 display module.

Frankly trying to figure out what the point of this new EVE5 is.

Jonathan,

If you would consider using out displays, all of our 3.5" to 7" use the GT911 touch, we decided to keep it simple and standardize our touch controllers.

We have released our new Main EVE C Library, Basic Demo and Example Code.

This repository contains:

EVE C Library for BT815, BT816, BT817, BT818

Demo Code: Basic EVE Demo and PNG Transparency Demo

Executable files for the Demo Code for Windows

RFTR Electronics uses a number of EVE2 and EVE3 displays, here is a fantastic intergration of our 3.8" 1U 480x116 1000cd/m2 display with Capacitive touch!

QuoteRFTR's IA20006000P50 is a reliable ultrawide-band 100W power amplifier instrument operating between 2000-6000 MHz and suitable for CW or Pulsed waveforms. This amplifier can be used in different applications such as radars, datalinks, mobile jamming or UAVs in S and C bands.

Ever wonder if it’s you or the hardware, wonder how a design will look on the display? This software is made for you. Drag an image onto your EVE display!

This forum needs a like button. 

Now I kind of want one.
But holy smokes, 5 gallons? That is like 20l?
That is maybe something to recommend for the company restaurant.

Yes, it is a lot, it is designed for Cafes I believe. They even have a 380L version if you really need a hit!

5 gallons of coffee cold brew under 2 hours!!! We have been working with Brew Bomb for several years, being one of our first EVE3 customers!
