The Adafruit Sparkle Motion Mini is a compact ESP32-based WLED driver board with USB-C power input up to 5V 4A, dual 5V level-shifted outputs, built-in microphone, Stemma QT I2C port, GPIO breakout pads, and integrated NeoPixel.

TheAdafruit Sparkle Motion Miniis part of ourseries of “Sparkle Motion” boards, which are our attempt to make thebest smallWLED-friendly smart LED driving board in the whole world. Our resident mermaid,firepixie, makes a lot of projects with WLED, and she loves it! So, hw can we make something powerful enough to drive advanced LED projects that need a compact design?

TheMiniversion of the Sparkle Motion is a simpler version of our full-featured Sparkle Motion; it doesn’t include the high voltage support or IR receiver, to make it under 1 square inch in size!

This version includes a pre-soldered terminal block, which means no soldering is required to get started: a small screwdriver will get you going instantly. However, the board is bulkier, and the terminal block overlaps half of one of the breakout pads. (We also sell a Mini Sparkle Motion – WLED-friendly ESP32 NeoPixel LED Driver, which comes without the terminal block).

By using a 4-layer board and double-sided assembly, we’ve put together this feature set:

• Power via USB Type C for up to 5V 4A input –you can use off-the-shelf USB battery packs for portable operation.
• 4Amp resetting fuseto protect from over-current drive
• ESP32mini module with built-in antenna port – the classic ESP32 has the best WLED support, even if we’d prefer the ‘S2 or ‘S3. Comes with 4 MB of flash, dual-core 240MHz Tensilica, WiFi, Bluetooth LE, and Bluetooth Classic support.
• USB-serial converterwith auto-reset
• Two output signals plus 5V power and ground – both signal outputs are level shifted to 5V. These are on 0.1″ spaced breakout pads.
• Extra 2×3 0.1″ breakout padswith4more GPIO plus 3V power and ground.
• Built-in I2S microphone
• Stemma QT I2C portto connect external sensors/OLED/etc
• User button on GPIO 0plus Reset button
• Red built-in LEDon pin 12
• Small built-in NeoPixelon pin 18
• Separate analog/digital input JST portfor analog input, potentiometer, microphone, or externalIR receiver on pin 13
• Compact enough you can use it for wearable projects– 1.2″x0.8″ / 30mm x 20mm size with mounting holes

While we recommend it for use with WLED, it will also work fine as a compact ESP32 board for use with Arduino, ESP-IDF, MicroPython, CircuitPython, or any other ESP32-supported codebase.

Comes as a fully assembled driver board with a 3.5mm terminal block

Also, unlike the bigger version, we dropped the on-board IR receiver; however, it’s easy to add one byplugging in a JST SH 3-pin socket cableandslotting in an IR receiver module.
