+## Feedback Loop
+The simplest way to test the SPI interface is with just a jumper *(wire)* and looping a data transmission from the **PICO** GPIO pin; back into the **POCI** GPIO pin. For this example, users are free to utilize any method or hardware they have to connect the **PICO** and **POCI** GPIO pins together. However, we recommend some IC hooks for a temporary connection.

+## Peripheral Device
+A more direct method for testing the SPI interface is with an actual SPI device. Users are free to utilize any hardware they already have; however, we recommend the [BME68x environmental sensor](https://www.sparkfun.com/products/19096), below. Its SPI pins are broken out on the edge of the board and can be easily connected to the RA6M5 Thing Plus. In addition, a [hookup guide](https://learn.sparkfun.com/tutorials/1168) and [Arduino library](https://github.com/BoschSensortec/Bosch-BME68x-Library) for the sensor are available.
