Introduction

LedBox V2 / V2.1 is a fully contained, sound reactive, ESP32 based module for controlling 5-12V addressable LED strips (WS281x, SK6812, etc.), supporting both 3-(VDD,DAT,GND) and 4-(VDD,DAT,CLK,GND) wire configuration.

The module (V2 & V2.1) has a dedicated step-down converter, which allows to seamlessly use both 5V and 12V strips (input voltage has to match strip's voltage). It also contains a digital MEMS microphone, side button, 32kHz IR receiver, 10A safety resettable fuse, 1000µF buffer capacitor, 3.3V/5V level converter for both Data and Clock lines, together with an impedance matching resistor. These features ensure maximum functionality, safety, and led strip compatibility, all in a small 3D printable enclosure.

LedBox V2.1 has these additional features:

• MOSFET that automatically disconnects the LED strip power when in standby
• Potentiometer for precise impedance matching
• 3 unallocated GPIO pins for possible expansion

Purchased module comes with the latest version of sound-reactive firmware.

Specification

Firmware versions

The original precompiled SR WLED firmware has a disabled IR control. Therefore, it is recommended to use builds from this repo, which are compiled with correct pin/microphone settings and IR control support, to work with the module straight out of the box.

The firmware is compatible with both, V2 and V2.1.

Version	Firmware
0.13.3	LedBoxV2_SR_WLED_0.13.3.bin
0.13.2	LedBoxV2_SR_WLED_0.13.2.bin
0.12.0	LedBoxV2_SR_WLED_0.12.0.bin

Gerber files

Do you share the Gerber files? I try to order PCBs on your PCBWay account/affiliate but it cannot be ordered - i cannot find gerber files on this Github page.

Gerber Files for the PCB

Hello,

I really appreciate your fantastic work!

Is there any chance to get the gerber files? So I can order your great design on jlc?
Is there maybe a partlist too?

Thanks for your help!

Boot mode

According to the schematics, GPIO0 is pulled low directly to GND without a 10k resistor. How will this work? Since GPIO0 has a 45k pullup resistor, how would you be able to pull it low and enter boot mode?

12V led strip

How it work with 12V led strip like WS2815?
WS2815 need 12V logic level.
