### ⭐⭐⭐⭐⭐ outstanding device
*by L***H on November 23, 2024*

works like a charm. designed and built well. the TTL port is very convenient for microcontroller comms. RS-232 port operates very smoothy and is not jerky like cheaper USB to serial converters. I use the device with OpenBSD and FreeBSD. Also works with Linux.
