This number does nothing Ever wondered about the ubiquitous 'Serial.begin(115200);' in your Arduino projects? It turns out, with boards like the ESP32-S3 offering native USB support, this baud rate doesn't really matter when streaming data. My tests even showed surprising results with different speeds using Arduino and ESP-IDF, highlighting potential in USB full-speed capabilities. I dove into raw performance testing, and saw deviations from expected UART limits. Check out the full video and explore the results if you're curious about maximizing your data transfer speeds! 12 August 2025
I broke it and then i fixed it Started off on a techie adventure with an RP2040 DVI board from Adafruit, aiming to get the pico-zxspectrum going. Things started acting haywire once the USB hub got involved, ending in a complete shutdown, intuitive diagnosis showed the power pin was a ghost town! After pin-pointing (and removing) the dead IC, I performed a delicate soldering operation to bless it with a new 3V3 regulator. Working the kinks out with the resolution led to a thrilling revival and, voila, we were back in business with DVI output and SD Card support! 01 July 2024
