Clear Acrylic Mounting Plate for TPS3116D2 Class D 2.1 Bluetooth Board

Bottom line: This is a focused review of the clear acrylic mounting plate designed specifically for the TPS3116D2 class D 2.1 Bluetooth amplifier board, and it will appeal to hobbyists and DIY speaker builders who need a simple, clean way to secure the board. In this review the biggest reason to buy is the combination of rigid, 3 mm construction and pre-labeled knob positions that eliminate guesswork during assembly, letting builders finish a portable Bluetooth speaker project faster and with a professional look.

Key Features

• Easy installation: The plate is cut to fit the TPS3116D2 board so mounting holes and spacing make installation straightforward and reduce trial-and-error during assembly.
• Thick, rigid construction: At 3 mm thick the acrylic supports the amplifier board without extra bracing, giving a solid feel in portable or bench-mounted projects.
• Pre-labeled knobs: Each knob position is etched on the front of the plate, making it simple to identify controls and avoid mis-wiring or mis-labeling when building an enclosure.
• Custom finish option: The clear plate can be painted on the back side to add color while preserving a glass-like finish on the front, enabling a polished final appearance.
• Designed for projects: The plate and TPS3116D2 board pair is presented as a ready solution for portable Bluetooth speaker builds, reducing parts sourcing time.

Who It's For

This mounting plate is aimed at hobbyists, makers, and small-scale builders who are assembling a TPS3116D2-based Bluetooth 2.1 amplifier into a custom enclosure or portable speaker. If you value neat presentation and a quick mechanical fit, the pre-labeled controls and sturdy acrylic save time and improve the final look.

It is less relevant for users who need weatherproofing, custom metal faceplates, or who prefer fully integrated commercial chassis; those projects may require different materials or thicker structural panels than a 3 mm acrylic plate provides.

Pros & Cons

Pros

• Clear, professional appearance that can be customized by painting the back side.
• Sufficient rigidity for the TPS3116D2 board thanks to 3 mm thickness without added bracing.
• Pre-labeled knob etchings reduce assembly errors and speed up wiring and setup.
• Straightforward fit for portable Bluetooth speaker projects, simplifying parts selection.

Cons

• As an acrylic plate it is not as impact- or weather-resistant as metal alternatives.
• Limited to the TPS3116D2 form factor, so it will not fit other amplifier boards without modification.
