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.
A simple level shifter to control WS2812/WS2813/Neopixel with a 3.3V GPIO pin
Instead of using level shifter ICs or MOSFETS you can simply sacrifice 1 LED to do the level shifting for you. The voltage for that sacrificed LED needs to be lower than 5V. Using a diode to reduce voltage to 4.3V works.
Note that the brightness of that LED will be lower than that of the other LEDs. So you may want to...
A simple PCB for driving a string of 5v WS2812 (or similar) Addressable LEDs using an ESP32 development board.
Input is via a 5v 2.1mm DC barrel jack. Output is 5v via a 3pin terminal block.
Has connections for an INMP441 I2S microphone and 3 momentary switches.
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...
Breakout Board for driving WS2812 LED strings from Wemos D1 Mini and External 5VDC Power Supply.
Includes 3.3 -> 5V Level Shifter on D4/GPIO2 for WLED software compatability.
+5VDC and GND are on copper areas to maximize current availability for LED strips
<p>An ESP8266-based gadget with 2xAA NiMH batteries charged by a solar panel, and sockets for I2C and UART ports, intended to be used with the AM2320 temperature / humidity sensor, an I2C OLED display, HC-05 Bluetooth module and a HC-12 433 MHz low bandwidth module. Contains 4x WS2812 RGB LEDs, and a single button.</p>
<p>In its basic form, it's a solar-powered ESP8266 gadget with WS...
Very simple power board for a Wemos D1 to power a strip of LED's aimed to be used together with the WLED software project to control the strip.
Work In Progress and **NOT** tested yet, use with caution!
A wireless high-speed ArtNet/DMX bridge for the contest at https://jlcpcb.com
It receives ArtNet DMX data via TCP/IP and transmits DMX data nad control data for NeoPixel / WS2812 / WS2811 LEDs.
It can also act as a slave device with LEDs in 802.11LR mode (esp32 specific long rang mode)
* 802.11LR ArtNet Node & ArtNet Master
* Approx. 100-200 FPS
* Over-the-Air Updates
* Powered by 5V
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...
