The μArt Kit

The μArt Kit

Overview

μArt is an isolated USB to UART-TTL adapter which you can use any time you want to connect a UART to your computer’s USB port, regardless of voltage levels, electric potentials, and communication speed, and whether it is used for data exchange or for programming Arduinos, ESPs, or other devices.

In this kit, this versatile high-quality device comes together with a Micro USB cable, a split “squid” cable that mates with the μArt using a single connector (female ends), a ribbon jumper cable (male ends).

Beschreibung

µArt aims to solve common problems of existing UART adapters by 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, providing signal integrity, and measures to improve usability. You don't need to worry that a tiny mistake will lead to a damage of expensive connected devices.

USB-UART converters are used during initial board bringup, for debugging and development, for flashing firmware, for exchanging operational data, for controlling peripherals, as service ports in the field, or as diagnostic interfaces during analysis. If you work or hack in the electronics engineering, computer engineering, or embedded systems fields, a UART adapter is most probably is one of your essential tools.

The µART will be of value for a wide public, starting from newbies to experienced engineers. Industry professionals will value being able to depend on the μArt and being able to focus on their work without having to second-guess their tool. Hobbyists and students, who can make mistakes more easily, will like that the μArt isolates faults and prevents damage to surrounding equipment.

You'll also find this device very useful in various applications together with Raspberry Pi, Arduino or Espressif. Moreover, the μArt supports non-standard and custom baudrates (such as 128000) so that you can use a fast and reliable setting for your MCU.

Main Features

  • Wide working voltage of 1.8 to 5.4 V, making it suitable for most projects, be it single-board computers, microcontrollers, FPGAs, or low-power electronics.
  • RXD, TXD, DTR, RTS, and CTS. Usable not just for basic communication, but also for flashing various modules from Espressif and multiple Arduinos such as the Pro Mini, Fio, or Arduino Pro. Hardware handshaking allows for reliable high-speed UART.
  • Non-standard baudrate support, so that you can use it with standard-clocked microcontrollers and still have a low error-rate. 
  • Up to 3 Mbaud transfer speed, the highest in the industry. This is enough bandwidth to stream uncompressed high-quality stereo audio.
  • Complete galvanic isolation, even for mains-level and higher voltages. Electrical current cannot flow between your computer and the other board. This provides safety for you and your computer, while also helping to keep noise levels down.
  • Reverse polarity protection. The converter will survive even if you mix up the power pins.
  • Over-current protection on IO pins. Made a false IO connection by mistake? Don’t worry, the μArt and your other board are both safe.
  • Pullups on all inputs, so that disconnected pins don’t cause funny things like garbage random input, a ruined terminal app, or corrupt application state.
  • Judicious filtering. Each IC in the converter is decoupled using multiple capacitors, both locally and in bulk. The USB signals and power are filtered, and sensitive pins are protected with RC networks.
  • Multi-level ESD protection for all interfaces. ESD damage is tricky because things can seem to work for a while after an ESD event, and you don’t need visible sparks to have it.
  • Voltage auto-sensing, meaning the converter will automatically use the correct voltage levels for UART communication.
  • Cross-platform support, with readily available and mature drivers for Windows, Linux, MacOS, and more.
  • Suitable for communicating with low-noise circuits, supported by the filters, the isolation, and careful layout.
  • GPIO pins that you can control directly over USB, parallel to the UART lines. They can also be reconfigured in software for alternate functions (for example, TXDEN for RS-485).
  • Four LEDs, each of different color to make them immediately distinguishable. One lights up if power is connected, two indicate RX/TX activity, while the last one is connected to a GPIO, giving you visual feedback about its state without special software on the host computer.
  • Four-wall shrouded header protects against ESD from fingers and from shorts by dangling wires.
  • Custom-designed case, professional and ergonomic, giving both mechanical and electrical protection, and a cool transparent-translucent look.

Scope of delivery

The μArt comes in a custom-designed plastic case by default and provides mechanical protection as well as adds to the electrical protection. Additionally, following cables are included:

  • A high-quality Micro USB cable by KabelDirekt
  • A split “squid” cable that mates with the μArt using a single connector (female ends)
  • A ribbon jumper cable (male ends)
