About Serial USB Terminal

'Serial USB Terminal' is a terminal / console app for microcontrollers, arduinos and other devices with a serial / UART interface connected with a USB to serial converter to your android device.

This app supports USB to serial converters based on
- FTDI FT232R
- Prolific PL2303
- Silabs CP210x
- Qinheng CH340
and devices implementing the USB CDC protocol like
- Arduinos using ATmega32U4
- Digispark using V-USB software USB
- BBC micro:bit using ARM mbed DAPLink firmware

To connect USB to serial converters, your android device must support USB OTG aka. USB host mode. Most devices support this today, but please check with one of the various USB test apps, if host mode is enabled in your android kernel.

Could not work much better. I've found this very useful for example when testing the range of NRF24L01 modules. I can just hook up a micro USB powered microcontroller on my phone and watch the serial debut output through the app.

Very nice to read values from scales. Not only this APP works fine but I do not need a PC or notebook to do the job! I set up the scale to send weight values continually, then a simple awk under Linux generates a list of individual weights from the APP exported file. A suggestion: It would be nice to have the exported file encoded as UTF-8, e. g. Thanks for the job!

Liked it so much I bought with a smile. Connects to my Prolific 2303 and CH340s cleanly which means I don't have to carry my laptop to every service call. Customers are amazed to see me arrive with just a small tool kit and plug my S7 in and talk to their systems. To make it perfect, needs Xmodem file transfer. If it gets this I can do firmware downloads to! It has to get 6 stars then - I'd even buy it again!!! ;-)
