Display for the [[clectric Display Arc]] Per Gemini: If you are sourcing this for a custom module, the undisputed community standard for that specific 2.4" 240x320 ILI9341 display comes from **EastRising** (often sold through BuyDisplay). Because you have the choice between integrating the raw ribbon cable yourself or using a pre-made PCB, they offer two distinct part numbers. Here is exactly what to look for: ### 1. The Bare FPC Ribbon (For a super-slim 2U layout) * **Part Number:** ER-TFT024-3 * **What it is:** This is just the raw glass screen with the delicate, golden FPC ribbon tail. * **Why use it:** It is incredibly thin (only 2.6mm thick). You will need to place a 39-pin FPC surface-mount connector directly onto your custom Arc PCB to plug it in. It takes more layout work, but it guarantees the screen sits perfectly flush behind your 50mm AE faceplate. ### 2. The Breakout Board Module (For easy prototyping) * **Part Number:** ER-TFTM024-3 (The "M" stands for Module) * **What it is:** This takes the bare screen above and pre-solders it to a rigid green PCB with standard 0.1" (2.54mm) pitch pin headers sticking out. * **Why use it:** You can plug this straight into a breadboard or solder standard female headers onto your Arc board to mount it. *The Warning:* Because it includes its own PCB and headers, the total thickness balloons to around 5mm or 6mm, and the physical footprint is slightly wider, meaning you have to be much more careful with your AE panel standoffs. ### The Premium Alternative (Adafruit) If you don't want to wait for international shipping from BuyDisplay/EastRising and just want a guaranteed, high-quality 2.4" ILI9341 breakout board delivered in a few days to test with your Spark prototype: * **Adafruit Part Number:** 2478 * **What it is:** Adafruit's official 2.4" SPI TFT breakout board. It has rock-solid voltage regulation built-in, and they provide excellent 3D step files if you are modeling your 2U faceplate in CAD.
