“This is a great board, especially given the low price. It lets you connect all sorts of electronics to your PC. Just the UART over USB would be worth the price for me, but it also supports I2c and more, which is great.”
“Great product brings USB-Serial conversion into the USB-C era and adds some bells and whistles. Works in Windows 10 out of the box as a FTDI style USB-Serial. Also well supported in Python with a custom HID interface for I2C, GPIO and a low-end ADC (although in most cases probably to connect a better chip over I2C).”
