NLED Dual Level Shifter Board

This dual channel level translator(shifter) is used to convert 3.3 volt signals to 5 volt signals. It features on-board low drop out linear regulators for both the 5 volt and 3.3 volt rails. That allows it to support a VIN of up to 12 volts, which makes it easy to connect to other devices. The TXS0102 I.C. allows speeds up to 24Mbps, designed specifically for addressable LED pixels which utilize clock and data lines, or other types of SPI based communication. The layout of the board allows it to be used inline with standard wiring for adressable pixels, no tricky wiring or jumping.

Pixel Differential SPI Board

Converts TTL SPI signals into differential signals and back to TTL SPI. Useful for long distance SPI communication with various LED pixels and other uni-directional SPI devices. Featuring dual in/outs, for either sending clock(CLK) and data(DAT) for synchronous chipsets, or dual data(DAT) in/out for asynchronous chipsets(such as WS2812 and similar).

Short Feature List:

• Supports wide voltage range for both 5 volt and 12 volt type pixels.
• Supports standard SPI(clock and data) or single-wire asynchronous (data)
• Designed for LED Addressable Pixels, but can be used for other SPI networks and similar uses.
• Supports all pixel chipsets. WS2801, WS2811, WS2812, WS2813, APA102, LPD8806, etc.
• Allows pixel data to be transmitted long distances. Depends on wire, enviroment, and chipset.

NLED DMX & RS485 Isolation Board

Update: Upgraded to version 2 hardware, same functionality and form factor. Improved hardware and layout, added data direction connection.

This simple device offers full electrical isolation for differential signals, such as DMX or RS485. Based on the venerable SN75176 transciever with a dual digital isolator and 1:1 DC-DC transformer. The device accepts a TTL input signal when setup to transmit and outputs a TTL signal when setup to receive. The differential conversion is handled by the transciever. Accepts voltages from 5 to 12 volts, but always outputs TTL(0 to 5 volt) signals. This device works with many NLED products and controllers, but would also work with any Arduino or other embedded device as it communciates with standard TTL signals. For details on electrical isolation specifications, please use the BOM to look up part datasheets for details.
