DIY Bluetooth Speaker Kit with FM Radio

This all-in-one kit lets you build a dual-channel Bluetooth speaker that also receives 87-108MHz FM radio. It includes 12 LED lights that flash to the music and a remote control for volume, mode and channel changes. Power comes from any 5V USB source such as a phone charger or computer port.

STEM learners and hobbyists who want hands

The kit is aimed at school STEM projects and anyone who enjoys assembling their own audio gear. Buyers who want more storage or a ready-to-use speaker without assembly should look at something else. No enclosure is included, so you will need to provide your own housing.

15cm wire antenna for 87-108MHz FM reception

A 15cm crimped wire serves as the FM antenna and plugs into the Bluetooth receiver board. Auto-search scans and stores local stations as P01, P02, P03 and power-off memory recalls the last station. Sensitivity adjustment on the back controls how the 12 LEDs react to the audio signal.

Questions about this item

What comes in the DIY Bluetooth Speaker Kit and what must I provide separately?

The kit includes the Bluetooth receiver board, 12 LED flashing lights, a 15cm wire for the FM antenna, a 3.5mm audio cable, and a remote control. You must supply a 5V power source such as a phone charger or computer USB port capable of 2A for best sound quality.

Which version or capacity of this kit should I choose for a school STEM project?

Only one version of this kit is offered. It combines a Bluetooth speaker, FM radio covering 87-108MHz, 12 music-reactive LEDs, AUX input, USB and TF card playback, and a remote control in a single package.

What does the 87-108MHz FM range mean when the speaker is assembled and in use?

Once built, the kit works as a digital FM radio that auto-scans and stores every station it finds between 87 and 108MHz as presets P01, P02, P03 and so on, and remembers the last station after a power loss.
