The PixelBlaster Nano is a feature-rich WLED controller in a compact form factor (32mm x 53 mm), offering high-current capabilities for any addressable lighting project you may have. It has all the features of much larger boards but at a cost point you cannot ignore. It supports virtually all LED strips and serial matrices using single-wire protocols, such as the WS2811 and WS2812B, to SPI (clocked-data) protocol devices, such as the WS2813 and SK9822, in 5V, 12V, 24V, and even the latest 36V strips.
******** 
- Uses the workhorse ESP32 dual-core 240MHz processor.
- Two channels of 5-volt logic-level translated outputs using ultra-fast and high-current LVC technology with matched and modeled serial inline resistors for high quality signal drive over short or long cables.
- Low-profile Wago push-button terminal block for easy and secure electrical connections.
- Compact form factor of 32 mm x 53 mm.
- High-quality 4-layer impedance-controlled PCB with gold-plated connectors (ENIG) for durability and corrosion resistance.
- ICS-43434 I2S 24-bit digital microphone with a sensitivity of -26 dB FS and SNR of 64 dBa.
- Onboard ATtiny1616 controller manages the AP33772S Power Delivery 3.1 sink controller.
- Input power: 5-36 volts @ 15-amp max. via high-current 5.5mm x 2.1mm DC power jack, or 5 volts @ 3-amps max. via USB-C connector.
- 15-amp replaceable power fuse.
- Onboard 100-amp Trench Power MOSFET "relay" that reduces current draw to just 80mA @ 5V when LEDs are turned off.
- Overvoltage protection circuit on input power that shuts off power to LEDs and the board
- 330µF bulk electrolytic capacitor on power output to smooth power delivery.
- Electrostatic Discharge (ESD) protection on all inputs.
- 38kHz Infrared Remote Receiver (IRM) compatible with all WLED-supported remotes.
- Supports ESP-NOW based remote controls.
- Easy flashing of custom firmware or upgrades through the USB-C connector.
- Pads exposing three ESP32 GPIOs for custom functions.
- Output pads exposed for hardwired solder options.
- Comes with a custom 3D-printed PLA+ case (design files available upon request).
- Comes with JST-SM 3 or 4-pin pigtail connector.
- Comes pre-flashed with the latest version of WLED.

- The PixelBlaster Nano PD comes pre-programmed from the factory with the lastest version of WLED. To update WLED, simply follow the instructions here under Software Update Procedure, Method 2.
- To reflash over the USB interface simply go here. (Note: after reflashing due to a driver issue, disconnect the board from your PC and connect to a power adaptor where you can then enter in your WiFI credentials via the AP.
