mlab-modules / usb232r02

Universal USB-UART converter ideal for prototyping high-quality devices. USB Full Speed/Full Handshake support.

USB232R02A

The module USB232R02A is a versatile and high-quality converter from USB to serial UART with 3.3V CMOS drive output and TTL input. It features a 5V-tolerant input and utilizes the reliable FT231XQ chip from FTDI The converter uses FT231XQ chip from FTDI, ensuring maximum compatibility with all major operating systems. With supports for Full Speed USB and Full Handshake UART signals.

The module provides the ability to power your devices via 5V from USB and 3.3V from the integrated power source simultaneously. The protection of the host device for overcurrent is realized by reversible fuse (750mA). 5V header is powerd from USB bus (trought fuse). The 3.3V power source is supplied from an LDO integrated in the FTDI converter. The 3.3V current limit is 50mA.

What makes this module special?

USB23202A is differ from other USB-UART converters with its compatibility with MLAB standards, this fact will save any engineer or maker o lot of time. One of its key features is a unified dimension and pattern of M3 mounting screws that can be used to create a solid foundation and ground plane for your complex designs, thanks to its aluminum mounting board ALBASEx. This not only ensures mechanical durability but also makes it easy to mount your device into your final designs. With uniform cable wiring methods, this device protects your design from unnecessary malfunctions, providing you with a tool to easily and quickly prototype your high-quality devices. Invest in the USB23202A and take your designs to the next level!

usb232r02's Issues

Různá svítivost RX/TX ledky.

RX a TX ledky jsou aktuálně v konfiguraci zelená/červená a mají u sebe stejný odpor. Bylo by vhodné změnit odpory tak, aby měli podobnou svítivost.

Alternativně lze sjednotit RX,TX barvu na červenou a zelenou využít pro #3

Missing power LED

Na modulu není LEDka indikující přítomnost napájení. Vzhledem k tomu, že tento modul často slouží jako zdroj napájení, tak by bylo užitečné, aby takovou indikaci obsahoval.

USB signals needs to be routed differentially

Vbus should be routed in the opposite direction from pin 5 of U1. Then D- and D+ could be routed parallel with the same length. Similar constraints apply to DM and DP signals.
