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?

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! 🚀

Close-up of the IoT HDMI Mux PCB with three HDMI ports connected.
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
