The TBS01A SDI-12 to UART module is a bi-directional interface for the conversion of commands and data into SDI-12 format and vice versa. The module is plug and play, targeting cost sensitive data logging applications. It offers low current consumption, small footprint and easy integration into products which require a SDI-12 interface.

The user does not need to invest any time for the implementation of the SDI-12 protocol and interface hardware, as this is an integral part of the SDI-12 UART interface module.

The TB01A contains all the necessary components of a complete SDI-12 interface. It includes SDI-12 front-end, controller, crystal and passive components.

TBS01A has been engineered specifically for applications where cost, performance, time to market and ease of integration are prime considerations.

In this version, the TBS01A comes in combination with a breakout board.
