FM Microphone Transmitter Module 5V, 24 × 10 mm Board

✅ Save room in the case. The board measures about 24 by 10 mm, so it leaves room in a project enclosure.

✅ Skip the extra capsule. An on-board microphone picks up sound, so no separate capsule is needed for basic use.

✅ Set your own frequency. The tuning adjustment lets you match the module to a compatible FM receiver.

✅ Wire power and aerial. Connection pads are marked on the board for the regulated supply and an external antenna.
