El Olimex USB-SERIAL-L is a device that has managed to stand out in the USB to serial converter market thanks to its advanced features and its design with both professionals and electronics and programming enthusiasts in mind. This device, developed by Olimex, is not just "one more" in its category, but includes features that make it truly versatile in various technical environments.
Thanks to its nature as hardware open source, the USB-SERIAL-L not only allows for great flexibility in use, but also promotes collaboration and customization within the tech community, something that sets it apart from other, more basic products. Below, we'll take a deeper look at all of its specifications and what makes it so special.
Main features of the Olimex USB-SERIAL-L
This model has a series of features that make it a essential tool for developers and technicians who need to work with serial devices. One of its strongest points is that it supports transfer rates of up to 3 Mbps, surpassing other models in the same range that only reach 1 or 2 Mbps.
- Multiple voltage level support: Its adjustable design allows working with ranges from 0,65V to 5,5V, making it ideal for interfacing with a wide variety of processors, SoCs or FPGA systems.
- Signal amplitude: It offers full support for Tx, Rx, CTS and RTS signals. This means that it is able to efficiently handle some automated functions, such as starting and exiting certain bootloaders.
- compact design: Its dimensions are just 35 x 35 x 8 mm, taking up minimal space and having a plastic box that protects the electronic components.
- USB-C connection: This modern port ensures a stable connection and allows the device to be powered with +5V.
Advantages over other similar products
Compared to other models of the same brand, such as the USB-SERIAL-F and the USB-SERIAL-M, the USB-SERIAL-L stands out especially for including additional control signals such as CTS and RTS, something that other more basic models do not incorporate. In addition, its ability to adjust voltage levels makes it compatible with a greater variety of electronic devices.
Other products on the market, such as the BB-CH340T, can reach up to 2Mbps, but the USB-SERIAL-L exceeds this speed with support for up to 3 Mbps, making it more competitive for demanding tasks. This makes it a more advanced alternative in various technical applications.
User-focused design
A feature that many users appreciate is that the USB-SERIAL-L comes fully assembled and tested, ready to use right out of the box. Additionally, the package includes seven 200mm cables, which adds a level of convenience by eliminating the need to search for additional accessories.
The design also includes status LEDs for the eating, transmitting and receiving, making it easy to troubleshoot during use. To ensure reliable performance, the device uses the Silicon Labs CP2102N chip, which is known for its compatibility with both modern and older versions of Windows, Linux, Android and macOS.
Open Documentation and Support
The USB-SERIAL-L comes with a full documentation and accessible on platforms such as GitHub. This includes schematics in KiCAD format, design files and 3D models for the housing. Being licensed under open source standards such as CERN Open Hardware Licence, its adoption and customization in individual or group projects is encouraged.
Open support also includes drivers that are easily downloadable from the Silicon Labs website, although most current operating systems already include them pre-installed. This significantly reduces potential issues with the device. initial installation.
The device is available in the official Olimex store with a competitive price 9,95 Euros, making it an affordable option for professionals and hobbyists alike. In addition, its quality and functionality position it as an ideal tool for those looking for a versatile and economical solution.
With a robust design, innovative features and an open approach to the technology community, the USB-SERIAL-L stands out as one of the best options in its category to manage serial connections efficiently and reliably.
