TWELITE UART Datasheet
TWELITE module specialized for serial communication
1 - TWELITE UART (BLUE / RED) Datasheet
Model: MW-(B/R)-UART-(P/U)
TWELITE UART (BLUE / RED) is a wireless module equipped with a 7P interface.
1.1 - TWELITE UART (BLUE / RED) Datasheet
Latest Edition
TWELITE UART is ideal for connecting to external microcontrollers via UART. It implements a 7P interface that includes TX, RX, VCC, and GND.
The Serial Communication App (App_Uart) is pre-installed, allowing immediate wireless communication with microcontrollers, etc., simply by wiring.
Users can also edit and rewrite the application (firmware) themselves.

Precautions
Wiring Precautions
Inputting signals that do not meet I/O characteristics may damage the product.
For example, microcontrollers operating at 5V cannot be connected directly. Please use voltage level conversion (level shifting).
Also, RS232C cannot be connected directly due to different operating voltages. Use a signal converter between RS232C and UART.
General Notes
Please always evaluate and verify the product in your own usage environment.
For applications requiring high reliability or related to human life, please consult your distributor in advance.
