SRX_BARO00_DEV#

The SRX-BARO00-DEV is a small size, low power and high performance barometric altimeter board that intends to be integrated in robotic applications development. Its extreme compactness allows easy prototyping on breadboard and integration on host board with direct soldering of back side pads.

Coupled with the included c++ library, it allows precise measure of relative and absolute pressure, altitude or temperature!

Included components are:

How to wire board

_images/baro00-dev-wiring_spi.png

Sensors INT pads are available but their connexion is not mandatory for the boards to work. Proposed sensors parsing libraries does not use these features but the user can implement them if needed.

In the examples provided for esp32-s3 (app ESP32), the board is wired with the following pins:

  • baro_cs = 9

  • mosi = 12

  • miso = 13

  • clk = 14

Complete projects#

Complete projects can be used as examples and are ready to use for arduino platforms. The projects manifests and releases are available at Projects Manifests

Recommended projects are:

  • Sensors Parsing: compatible all arduino, reading of sensors

Sensors parsing#

If you do not want to use esp32s3, or just want sensors parsing, a reduced functionalities software is proposed. It includes parsing for the sensor of the board

  • LPS22HB barometer

… and an example main.cpp file with a loop implementation.

The software is compatible with all microcontrollers with using the arduino framework:
