Great Touchscreen for My BTT Setup! - truetrust

I recently decided to upgrade my 3D printing setup, focusing on integrating a cleaner control system with my Manta board. That’s why I picked up the BIGTREETECH TFT35 SPI V2.1 Touch Screen 3.5 inch Display IO2CAN 3D Printer PI V1.2 For BTT Manta M8P M4P Board CB1 Klipper Board. I was specifically looking to pair this with the BTT Pi board for a smooth Klipper experience, hoping for a responsive front end to manage my prints, and overall, it has delivered on that front.

Setting this up with the BTT Pi v1.2 was quite straightforward. The **touch accuracy** on this device is notably responsive; I tested it right away, and the calibration seems spot-on, which makes navigating menus much less frustrating than using just a knob. Other buyers seem to feel similarly, noting it’s a decent display for the ecosystem.

It really works as intended when paired correctly, creating a solid combination of the single board computer and the touchscreen interface. Everything functions smoothly, just as advertised.

Now, one important note I learned—and something I wish was clearer in the initial listing—is that this specific model doesn't automatically connect via IO2CAN to all carrier boards; I had to source an alternative connection method, which can be frustrating if you expect plug-and-play IO2CAN functionality out of the box for every configuration. Despite that minor headache, when it comes to pure function, the **fast shipping** meant I got to testing quickly, and the core display element itself is quite good. I also noticed one buyer mentioned a missing jumper for USB-C power testing, so be prepared to check all included components carefully upon arrival.

If you are already invested in the BTT ecosystem, especially if you are running a Klipper setup with the Manta boards and a CB1, this screen is a fantastic visual upgrade. It solidifies the localized control panel experience beautifully.

For anyone looking to finalize their BTT control stack with a responsive, dedicated interface, I highly recommend grabbing the BIGTREETECH TFT35 SPI V2.1. It’s a worthwhile addition to streamline how you interact with your printer.
