Never have less than a drawer-full of various USB to serial devices. We've all been there - late at night when you have to hack together an old PCB with a stray MAX232 on it, when one of these is what we really need! #embeddedsytems#firmware#hardware#development
Espressif programmer test success! 💻✨🔧
While developing boards, there are oftentimes we want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip (https://t.co/y9qH7vD83A) with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 up to the ESP32-P4! Here, we are testing it with a HUZZAH ESP8266 breakout board (https://t.co/DkzFdmpq7D), one of our first Espressif chipset products.
