If you need to have a logic shifter for your I2C bus, this is all you need. This will autosense the data's direction and act seamlessly in your design.

still working on the SI4732 Radio Project PCB with #Meshtastic functionality

we need to talk about that Ring Super Bowl ad

first PCBs of the year from @aisler.net are here! 🎉 (NNNI26 for €10 off this entire year!)

can't stop watching this clip of a tesla Optimus teleoperator taking his headset off before properly logging out the robot

Lots of Work and Brains went into this PCB KiCad Design. Equipped with an SI4735 & SI4732 FM Receiver, I2S MAX98357 3Watt Amplifier, SI5331 VCO,LoRa, Wifi, BLE CT62 ESP32-C3, LSM6DSV Gyro+Acc, RV3028-C7 RTC and an BME690 Temp, Humid eCO2 Sensor. Ready to Mount an 1.28" or 1.8" Inch Touch Display.

DIYables ESP32 WebServer (1.0.1) for esp32 by DIYables.io ➡️ https://github.com/DIYables/DIYables-ESP32-WebServer DIYables ESP32 WebServer library with WebSocket support #ArduinoLibraries #ArduinoLibs #esp32Libraries

0.645 x 0.645 mm is the size of this LDO! It's half the size of the 0402. Low Quiescent Current is here 340 nA The Dropout Voltage of 140 mV and 300 mA output current isn't so important. An ultra-low current switching regulator would work too, but this LDO has a significantly lower PCB footprint.

Have you ever used the autocomplete hotkey in KiCAD's PCB editor? Did you even know about it?

IMPORTANT AND DEEPLY EMBARRASSING CORRECTION: MAY 23rd and 24th!!!!!!!!!!

This Device really got me thinking: WHY 2x ESP32? The interesting part about it is: It is the same as Waveshare www.waveshare.com/product/ardu... de.aliexpress.com/item/1005009... Got one for 23 € Finally:ESP32 for BT sink and another ESP32-S3 for Display. Both ESP32 on one USB Connector

Design of a PCB for a simple FM Radio takes longer than expected. More and more ideas come up. Dual FM Tuner. I2S Audio, Synth VCO, BME690 Air Quality and #LoRa or #Meshtastic support. Did I mention ESP32-C3? Or Seeed Xiao Bord support?

Just in time! E-Traxx, a formula student team we recently partnered with, faced a last-minute PCB issue before their race. We reviewed and adjusted their design on a phone call, and with our 2 Layer Blitz service, we delivered the boards in just 3 days. Ready for the event! 🚀

When the client asks if you can 'just make the PCB smaller'… after routing is done.

The IoT HDMI mux is alive. Here's the progress so far: - USB, ESP32, WiFi & BT antenna all working - HDMI mux is muxing - Identified a missing +5V connection to the HDMI sink (this has been bodged) - Confirmed reliable 1080p60 output after the fix #IoT #ESP32

RAK12052-MLX90640 (1.0.1) for arduino by RAKWireless ➡️ https://github.com/RAKWireless/RAK12052-MLX90640 RAKWireless library for the matrix #ArduinoLibraries #ArduinoLibs

This is not a serious government.

Working on a small multiuse PCB layout. Works with E-Ink and LCD Touchscreen. Several Sensors on Board(Gyro, Mag, ACC, Temp, LuX), RTC, LiPo Bat Charger and BME688 Air Quality Sensor on a size of 28x26mm

I've always found circuit boards aesthetically inspiring, and in recent years this fascination has turned into a number of PCB-styled demos. I think a key inspiration for these has been the "Absolut Intelligence" vodka advert a couple of decades ago.

I've been so focused on the next #SqrDisplay prototype HW and case design that I forgot to finish the #Edge3S Carrier reference PCB - well, I just did and I even got a proper EdgeS3 CAD model done for the M.2 connector footprint. #maker #pcbdesign #soon

Updateing KiCad :-) to Version 9.0

New PCB Idea: #PCBPhotos ESP32-S3 + Round GC9A01 Display with some clever Sensors: BME690/BME688 for Air Quality, BNV080 for Air Quality(Grey Box), LSM6 Gyro+ACC, LIS3 Magnetometer, MAX98357 Audio Amp, ICS43434 Microphone, BH1750 Ambient Light, 2x WS2812 RGB LED. (ready to connect to #Seeed Display)

Greetings from the woods :-) I do not know what this deer wants to tell me

Mit dem ESP Offline Programmer lassen sich ESP-Boards ohne Computer mit Firmware bespielen. Das ist unterwegs oder für das Flashen vieler Boards nützlich. #ESP8266

Seed Display with self Made audio Extension works.. on my way to Bike Computer

First RX TX confusion this year😄

Redesigned a litte EINK Board. Now with RTC, Gyro, Magnetometer and a side RGB LED

K-type Thermologger PCB Works. Made with KiCad

Refinement of the PCB Design of a USB C Variable Power Supply using USB C PPS Standard

Redesigned a USB PPS Lab Power Supply. Based on jasontoo SparkAnalyser.

How IT started , how it ended. Dead sensor. Bought 3 gy87 on Ali. All dead

#Deye Wechselrichter in dem USA, Pakistan & weiteren Ländern wurden offensichtlich fernabgeschaltet. Darum: - Wechselrichter nicht direkt mit dem Internet verbinden! - Nichts bei Deye kaufen (vielen ja schon früher negativ auf wegen Fehler Relais, siehe #Deyegate) www.golem.de/news/chinesi...

You can not imagine how much time it takes for FineTuning a PCBDesign. Everytime you look at it you find some new issue that you just need to fix in a moment. Or all of a sudden you have a new Idea

Finished a NEW Design to fit on Seeed Display. Sent for PCB production today.

Wallswitch PCB with Environment Sensor and eink

Beertime

You remember this old Project: WifiWallSwitch with EInk Display? Had to make an update: With MAX98357 Speaker support, Magnetic Sensor QMC5883, BME280, Jog Dial, Rotary Encoder & LSM6DSO Gyro+ACC. Most should work on HomeAssistant ESPHome

Small Webradio "Version4" with some small improvements: Added LIS3M MagSensor, GC9A01 Round LCD Display, Jog Dial, BME280

News Thermologger PCB: About to put this MAX31856 ThermoLogger Design with ADG1607 Multiplexer into PCB production: 8 x K-Type Sensor Probes can be monitored at a time. Perfect to monitor your solar power plant or your heating system

Das #LoRaWAN Gateway um eine Mastantenne erweitert. Erstaunlich was das doch ausmacht (externe Antenne und ca 3m höher). Der Empfang hat sich hierdurch um einiges verbessert.
