Figure 11: UART modem
The Module UART is 1.8V voltage interface. If user’s UART application circuit is 3.3V voltage interface, the
level shifter circuits should be used for voltage matching. The TXB0102RGYR provided by Texas
Instruments is recommended. The following figure shows the voltage matching reference design.

Module supports the following baud rates: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600,
115200, 230400, 460800, 921600. The default band rate is 115200bps.
3.5 I2C Interface
Module provides an I2C interface compatible with I2C specification, version 3.0, with clock rate up to 400
kbps. Its operation voltage is 1.8V.
The following figure shows the I2C bus reference design.
