The USB Serial Terminal Ultimate is a must-have app for anyone in need of a real serial terminal console for easy access. This app supports popular USB to serial TTL chips including FTDI, CP210X, CH340X, and PL230X. It is extremely useful for debugging serial communication applications, such as Internet of Things projects.

With this app, you can easily set up the connection with your serial chip by configuring parameters like baud rate, stop bits, flow control, and parity. The received serial data is displayed on the app console, allowing for real-time monitoring.

Additionally, the app allows you to write and save scripts for later use, making it convenient for repetitive tasks. It also includes a collection of AT commands for popular Bluetooth and WiFi chips like HM-10, HC-05, HC-06, and Esp8266, providing easy access and control over your Internet of Things devices.

Please note that your phone or tablet must support USB-Host Mode and you will need a USB-OTG cable for connection. It is recommended to use a shorter cable to avoid possible voltage drops and Serial chips malfunction. Your battery level must also be greater than 25% to ensure sufficient power for USB Host detection.

The USB Serial Terminal Ultimate app supports various features such as support for CDC-ACM based devices, USB with OTG adapter and USB Bridge chips, FTDI based devices, CH340G and CH340X based devices, Prolific PL2303X based devices, Silicon Labs CP210x based devices, and all Arduino boards. It also offers easy export of console logs to CSV and Text formats, support for different baud rates, selectable data bits and stop bits, and various flow control options.

Overall, the USB Serial Terminal Ultimate app is a powerful tool for serial communication applications, offering convenience and ease of use. It does not require root permission and provides instant developer support.
