Appendix A: SolderCore Expansion Interface
The SolderCore range of sensors use a standard interface called SExI (Sensor
Expansion Interface). This standard allows a single development hardware platform
to be used to evaluate a range of sensors.
Referring to Figure 3, a SExI device is comprised of two sections. Each section has
common power pins consisting of 3.3V, 5V and 0V. If a sensor uses only SPI, only the
top four rows of pins are required. For I2C based sensors, only the bottom four pins
are required, in both instances the sensor foot print can be halved.
The SExI footprint provides for sensors that use simple UART connections. The Tx and
RX pins are located on the right hand side of the module.
The DIO line can be used as a digital input of output line. Many sensors use interrupt
lines, to inform the external electronics/processor that an even has occurred. In most
instances the interrupt line is taken to DIO.
AN can be either a Digital IO or an Analog output pin. Sensors that output readings
as an analog signal use this pin. The SenseCore shield routes this pin to the ADC pins
to the SolderCore / Arduino headers.
The right hand connector is marked with a thick white bar to easily identify it.
