===== - Names of the different bus instances for flipper board in Arduino =====

Unlike a classic arduino uno board, the flipper has multiple instances of each communication bus. 

To use each of this instances you need to call them by their names, in the following table you will find the matching between busses in the flipper schematic and arduino instances.

^ Schematics NAME  ^ Arduino NAME  ^
| I2C0             | Wire          |
| I2C1             | Wire1         |
| SPI0 | SPI |
| SD_SPI | SPI1 |
| USB | Serial |
| UART0 | Serial1|
| UART1 | Serial2 |
