Saber Board that is Proffie Firmware compatable, Larger in size, Includes integrated LiPo charger and Battery Protection Circutry.
Designed specifically to be assembled by EasyEDA stock parts.
4CH LED Full current control using 2xL7135 for 700mA (stackable to 3 for 1A) no need for external resistors
1 main Neopixel data line and 3 extra Neopixel or for accent leds
3.3v switchable power out for...
A ESP-12 IoT controller for RGB LED Stripe 5-12V.
3+1 channels through MOSFET, PWM and dimming functionality.
The MOSFETs can be replaced by NPN Power transistors (input resistors are as THT parts placed, the 10k pull down's not needed.
The 4th channel is a Logic level up-converter (3.3V->5V). Driven by a 2N7002, can be replaced with BSS138 or similar. Note that it's is a very small power output...
ATtiny85 controlled candle simulation using NeoPixels, LDR light sensor and IR remote receiver.
Low-speed, high resolution pixel poi based on WS2812B LED strip.
A dual microcontroller board for controlling "Neopixel" LEDs, with one micro dedicated to driving the LEDs while the other micro is busy reading push buttons, polling rotary encoders, reading IR remote signals etc etc.
The microcontrollers -two atmega328s -communicate with one another over their I2C bus. The very short wire run negates the need for the usual pull up resistors on the bus.
NeoPixel led strip controller, designed especially for led suits. It can:
- display animation - sequences of frames at regular (given) interval,
- switch animations on MIDI event - note on/off, velocity used for brightness adjust,
- MIDI over UDP over WiFi (UDP broadcast so far, but i'm working on multicast),
- use regular SD card to storage animations.
[These guys use them] for...
Level Shifter to run 5V NeoPixels (WS1812B) LEDs via a 3.3V SPI bus (e.g. Raspberry Pi).
The P-SPI header was designed in such a way, that the PCB can be plugged on top of the Raspberry without further cabeling.
The P-LED-DRIVE outputs the signal to the LEDs, while P-LED-SENSE _optionally_ connects to the output of the last LED in the chain.
Connecting P-LED-SENSE allows a software running on the...
LED controller for LED-strings, -strips and -rings with individually addressable LEDs.
The controller offers a wide spectrum of usefull functions:
- I²C front panel connector for a on display UI and rotary controller.
(for use with DUPPA.NET's I²C rotary controller and a I²C OLED Screen)
- WIFI AP AND Standard Mode, for use with and without existing Wireless network infrastructure.
Board for five individual Neopixel type APA 106 LEDs either 5mm or 8mm size. Two versions provided. The new one has positions for a large electrolytic filter capacitor and 1206 size decoupling capacitors (0.1 uF recommended) between LEDs. Not sure if all five decoupling caps are required, it may work with about three but positions are there.
Multiple Boards can be cascaded.
I did not provide...
*This design has not yet been built and tested*
Cascade-able 5 Chip Neopixel board suitable for decorative lamps especially using the ESPEasy NeoFlame plugin.
Should work well with any Neopixel application that is suitable for groups of five LEDs.
This board is for individual WS2812b LED chips. Not the ones pre-mounted on a heat sink pcb with resistor and capacitor already installed.
