Apr 1, 2023 · Hi! Pretty much the title, what's wrong with this schematic, what improvements could be made, etc. This is an esp32 board for general led projects, whether they are digital or analog leds. It can take up to 24v, and drive 5v leds even with that high voltage, at up to 15a. To program it I'll be using a UART interface, and then OTA updates. You can see the TX and RX pins on …

Aug 21, 2022 · I was wondering if you could possibly look over the PCB I have designed, it is a LED strip controller powered by an ESP32. I have have built simple boards before (and some slightly more complicated keyboard design boards) using Lolin / Wemos board that plug in to them to control LED strips for various lights around my house.

Aug 9, 2021 · Hi all, I have never submitted a schematic review before so hopefully I am doing it ok. I am newish to circuit design (have build some PCBs for keyboards and other small projects). I built quite a few lighting control projects (WS2812) using off the shelf eps8266 / esp32 dev boards and wanted to move over to designing something myself from scratch. This board should …

Jun 17, 2024 · PCB Review: LED driver & LEDs array automotive area Hello and thank you for reading, I designed my first schematic and PCB with following idea in my mind: to bright unused car rear light - some kind of personal project. There are 3 inputs:

Jul 31, 2022 · Based on the very helpful responses I got from my previous post previous post seeking review of my STM32-based keyboard with dimmable per-key backlighting, I've made adjustments to my design. Changes: Replaced dimming circuit with low-side N-MOSFET design (RFM04U6P) Corrected VBUS connection to ESD protection Removed standalone +5v TVS …

Jul 31, 2022 · Dear Community, I would like to receive your feedback on my schematic and PCB for LED Strip Controller Board called Universal LED Controller. The main purpose is to be able to easily control LED Strip of various kinds. This includes 12V RGB Strips with common anode and individual cathodes and 5V addressable LED Strips like the WS2801 and WS2812b. Main …

Oct 23, 2022 · Although you could easily buy a similar tealight LED candle circuit, I personally find that this circuit is a bit better at simulating a flickering flame than many of the cheaper tealight circuits out there, while allowing you to customize things like the LED color/flickering frequency.

Hi r/wled community, I’m excited to introduce the MagWLED-1, a compact and powerful LED strip controller that’s fully compatible with WLED. This tiny device packs a punch with its USB-C Power Delivery support, making it perfect for small to medium installations and even wearable projects.

May 4, 2024 · I'm trying to build a simple circuit with two 5mm LED's that will flash to look like a fake car alarm. Most of the schematics I've found online all utilize a BC547 transistor, a 1K resistor, and a 1,000uF electrolytic capacitor. Some circuits used a 470uF capacitor. The value of the capacitor determines the rate of the interval between flashes.

Feb 6, 2021 · Hello! I am trying to create an RGB LED (WS2812) matrix in KiCad 5. It's 16x16 chips, so 256 total. The schematics is easy enough using copy and paste, but is there an easy way to do the placement + layout in pcbnew? The create array function doesn't work because it doesn't change the refdes'. Is there an option that's easier than going full Python scripting?
