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.
It's half the size of the 0402.

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?

"When we see an extremely DIY project, you always get someone who jokes "well, you didn't collect sand and grow your own silicon". [Patrícia J.

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! 🚀

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.
