Budapest-based Karoly Pados has launched an isolated USB to UART-TTL adapter, the μArt, which claims it “tolerates common user mistakes without being damaged or causing damage to other hardware” and has already raised more than its required funding on Crowd Supply.
“It is no secret that there are many UART adapters on the market. So, you might ask, what’s the point of creating yet another one? The unfortunate reality is that despite the general usefulness of such devices, none of them seem able to solve the associated problems in a general and reliable way,” explains Karoly of the project. “This is where the μArt comes in, covering all use cases with a single device, and offering a reliable and robust solution that you can just trust to work right. The μArt has all the pins and features to enable various applications, protections to withstand or even prevent faults, means to preserve signal integrity, and measures to improve usability.
“The μArt is based on the principle that a UART adapter is your tool, and you should be able trust your tools to get the job done.”
The μArt’s features include a wide voltage range of 1.8V to 5.4V, support for non-standard baud rates, up to 3Mbaud transfer rates, complete galvanic isolation even up to mains voltage levels, over-current and reverse-polarity protection, and general-purpose input/output (GPIO) pins which operate in parallel to the UART lines.
More information is available on the Crowd Supply campaign page, which had raised more than 168 percent of its funding goal at the time of writing.
