+# UART Terminal for Flipper Zero
+[Flipper Zero](https://flipperzero.one/) app to control various devices via UART interface.
+
+## Capabilities
+- Read log and command output by uart
+- Send commands by uart
+- Set baud rate
+- Fast commands
+
+## Connecting
+| Flipper Zero pin | UART interface  |
+| ---------------- | --------------- |
+| 13 TX            | RX              |
+| 14 RX            | TX              |
+|8, 18 GND         | GND             |
+
+Info: If possible, do not power your devices from 3V3 (pin 9) Flipper Zero. It does not support hot plugging.
+
+## Keyboard
+UART_terminal uses its own special keyboard for work, which has all the symbols necessary for working in the console.
+
+To accommodate more characters on a small display, some characters are called up by holding.

+
+
+## How to install
+Copy the contents of the repository to the applications_user/uart_terminal folder Flipper Zero firmware and build app with the command ./fbt fap_uart_terminal.
+
+Or use the tool [uFBT](https://github.com/flipperdevices/flipperzero-ufbt) for building applications for Flipper Zero.
+
+## How it works
