When a control panel needs a human-machine interface, the first fork in the road is whether you're building a new interface or reviving an existing one. These two kits sit on opposite sides of that fork: one is an OLED display interface kit for the Infineon XMC4500, the other is a membrane keypad and touchpad repair kit for a KTP700 operator panel. Pick the one that matches the job you're facing today.
Quick verdict
If you're building a custom HMI around an XMC4500, the OLED interface kit is the natural choice. If you're repairing a KTP700 panel with a worn keypad or touch surface, the membrane keypad and touchpad repair kit is the one to get.
At a glance
| Feature | Infineon XMC4500 OLED Kit | KTP700 Keypad/Touchpad Kit |
|---|---|---|
| Price | USD 50.00 | USD 181.39 |
| Condition | New | Used |
| Part reference | KIT_XMC4X_HMI_OLED_001 | 6AV2123-2GB03-0AX0 |
| What it is | OLED display interface kit | Membrane keypad + touchpad repair kit |
Where the XMC4500 OLED kit wins
- It's designed around the XMC4500 series, so it's a natural fit for projects already using that microcontroller.
- The OLED display interface gives you a visual screen to integrate into your own panel design.
- As a kit, it lets you adapt the interface to your specific layout rather than being locked into a complete pre-built panel.
Where the KTP700 keypad/touchpad kit wins
- It zeroes in on a specific repair target: replacing the membrane keypad and touchpad on a KTP700.
- A repair kit like this is the direct path to fixing worn input surfaces without swapping out the entire panel.
- It's aimed at the KTP700 HMI assembly, which is what you need when a keypad starts failing.
Product notes
Infineon Technologies Kit Interface XMC4500 OLED Display
Priced at USD 50.00, the XMC4500 OLED display interface kit is an approachable way to add a display to an Infineon XMC4500-based project. It's listed as new, and the part number KIT_XMC4X_HMI_OLED_001 pinpoints the exact kit. Keep in mind that the item comes as pictured without extra parts or accessories, so you'll need a compatible XMC4500 board and wiring to drive the OLED screen. That makes it a strong fit for engineers and hobbyists already working with the Infineon platform, rather than someone looking for a complete, ready-to-mount HMI panel.
KTP700 Membrane Keypad + Touchpad HMI Repair Kit
The KTP700 membrane keypad and touchpad repair kit is listed at USD 181.39 and is meant for one specific job: replacing worn input surfaces on a KTP700 operator panel. The part number 6AV2123-2GB03-0AX0 gives you a direct reference for the HMI assembly. As a used item, it's a repair part rather than a brand-new component. This is not a tool for building a new interface; it's the targeted fix when a KTP700's keypad or touchpad stops responding reliably.
Final choice by use case
- Building or prototyping a custom HMI around an XMC4500? Go with the Infineon OLED interface kit.
- Repairing an existing KTP700 panel with a failed keypad or touchpad? Go with the KTP700 membrane keypad and touchpad repair kit.
Both products solve real problems, but they're not interchangeable. Choose the one that matches the project in front of you.
