// PiFi DAC+ v2.0 (Pi-DAC+ clone) connected to BPI-M3 on I2S1 / I2C2.
// The power, ground, and I2C pins are in the same position, but the
// I2S ones are not.
//
// On BPI-M1+, I2S0 and I2C2 or I2C3 would be used with jumper cables.
// On BPI-M2+, I2S0 and I2C0 or I2C1 would be used with jumper cables.
// On BPI-M3, I2S1 and I2C1 or I2C2 would be used with jumper cables.
// On BPI-M64, I2S0 and I2C1 would be used with jumper cables.
// On Pine64, I2S0 on Euler E and I2C1 on RPi header would be used with
// jumper cables.
//
// On ALL-H3-CC, I2S1 and I2C0 correspond to the Raspberry Pi pinouts.
// Alternatively, you could use I2S0 and/or I2C1 with jumper cables.
