Quick Start

This guide introduces the FoBE Breakout LPS22 and how to use it.

Hardware diagram

The following figure illustrates the FoBE Breakout LPS22 hardware diagram.

Mechanical dimensions

FoBE Breakout LPS22 is a single-sided 25.4mm x 25.4mm (1" x 1") 1.6mm thick PCB with two SH1.0 4-pin connectors and a set of 5-pin 2.54mm header holes. Fixing by 4 x 1.6mm Screw holes.

Interfaces

The board provides two 4-pin SH1.0 connectors, all providing the same IIC connections for MCU control.

Interface	Description
GND	Ground
3V3	Power supply
SDA	I2C bus data line
SCL	I2C bus clock line

And a set of 5-pin 2.54mm header holes, providing the same IIC connections for MCU control, plus an interrupt pin.

Interface	Description
GND	Ground
3V3	Power supply
SDA	I2C bus data line
SCL	I2C bus clock line
INT	Interrupt signal: Active Low

Configuration Jumper

The board features two jumper pad:

Interface	Description
LED-JUMPER	The PPS (Pulse Per Second) LED jumper. To save power, you can physically cut the trace between the pads of this jumper. You can later re-solder the jumper to reconnect the PPS LED.
LPS22-ADDR	The LPS22 I2C address jumper. The LPS22 can be configured to use either the default I2C address (0x5C: connect the JUMPER:H) or an alternative address (0x5D: connect the JUMPER:L).

Programming

FoBE Quill nRF52840 Mesh Example

The FoBE Quill nRF52840 Mesh development board provides multiple digital gpio; pins D2, D1, D0 are used in the example:

#include <TinyGPSPlus.h>
