Oh cool, another USB-UART bridge. I can get one for 1$ on aliexpress. Nice time and moneywaster bro. ~You Oh no, no. This board comes with a twist that makes it like 100x better. Take a closer look at that 3v3-out! What do we use our UART-based programming boards for? 3-sigma of times it’s either Arduino board, or ESP8266/ESP32 - based device. These rarely require more than 500mA of continous power, and therefore can be powered with standard USB port. /posts/lichtenblinks/ Mon, 01 Jun 2020 00:00:00 +0000 /posts/lichtenblinks/ I really enjoy cheap electronics. I think the pinnacle of XXI maker culture is DIY affordable electronics. Even though buying knock-off arduino from china may be somehow morally questionable, it certainly enabled me to overcome fear of accidentally frying my devkit. This freedom to make mistakes is probably why I ended in electronics field at all. Back in 2012-ish, I made my first somehow complex DIY project - RC tank that I controlled via SSH!
