ZRPi-3.5NSX Nextion Screen Case for Raspberry Pi and ZUMspot - Compact

In this review the ZRPi-3.5NSX case is evaluated for hobbyists building a compact MMDVM hotspot with an Enhanced 3.5' Nextion touchscreen. The bottom line: this case is for builders who want precise laser-cut fit and tidy enclosure for a Raspberry Pi (3B, 3B+, 2B or B+ or Pi 4B with thermal caution) together with a ZUMspot or generic Chinese MMDVM board and the included 3.5' Nextion screen. Its main appeal is the exact fit and clean presentation rather than active cooling or rugged outdoor protection.

Key Features

• Precise fit: Laser cut internal layers and stainless fasteners hold a Raspberry Pi and MMDVM board neatly, reducing loose cabling and wobble during use.
• Included touchscreen: The Enhanced 3.5' Nextion touchscreen ships with the case, letting users get a touchscreen interface without sourcing a separate display.
• Full body coverage: The case encloses components for a clean look and protects boards from accidental contact while still allowing necessary access to ports.
• Accessory support: Inner layers are designed to accept the Pimoroni Fan SHIM if a user later chooses to add active cooling for a Pi 4B.
• Hardware and extras: Stainless steel hardware, heat sinks, and rubber feet are included to improve stability and thermal conduction where applicable.
• Made in USA: Engineered and manufactured in Tacoma, WA, providing quality control and consistent build tolerances.

Who It's For

This case is aimed at amateur radio operators and makers building a compact MMDVM hotspot using a Raspberry Pi and either a ZUMspot or a generic Chinese MMDVM board. If you want a tidy, finished enclosure with an integrated touchscreen and a precise internal layout, this case fits that workflow well and simplifies assembly.

It is not ideal for users who require waterproofing, heavy-duty outdoor deployment, or sustained maximum performance from a Pi 4B without additional cooling. Also, connecting the Nextion screen may require extra soldering of pins or wires beyond the case instructions, so those uncomfortable with moderate hardware work should take care.

Pros & Cons

Pros

• Excellent build quality and design that customers report fits the Pi and MMDVM boards well.
• Includes an Enhanced 3.5' Nextion touchscreen so you do not need to source a display separately.
• Laser cut parts and stainless steel hardware provide a precise, durable enclosure with rubber feet and heat sinks included.
• Inner layers engineered to accept common fan addons like the Pimoroni Fan SHIM for better thermal options.

Cons

• The case is not waterproof and does not include active cooling, so Pi 4B users should monitor temperatures and avoid sustained full-power operation.
• Connecting the Nextion screen can require additional soldering of pins or wiring not covered in the case instructions.

Our Verdict

The ZRPi-3.5NSX is a strong choice for makers who want a tidy, well-made enclosure for a Raspberry Pi-based MMDVM hotspot with a 3.5' Nextion screen included. It delivers precise fit, solid materials, and useful extras at a sensible value, but buyers should accept that it does not provide active cooling or waterproofing and that some wiring effort may be required to connect the display.

Frequently Asked Questions

Does the case include a fan?
No, the case does not include a fan; inner layers are designed to accept the Pimoroni Fan SHIM if you add active cooling.

Is the Nextion touchscreen included and ready to plug in?
An Enhanced 3.5' Nextion touchscreen is included, but connecting it may require additional soldering of pins or wires not covered in the instructions.

Will this fit a ZUMspot MMDVM board?
Yes, the case is designed to fit a ZUMspot or compatible generic MMDVM boards such as Jumbospot models.
