Figure 2-21 Shield and Pmod power and I/O reference voltage user-links
One user‑link selects 3V3 or 5V I/O operations for the Shield 0, Pmod 0, and Pmod 1 interfaces.
One user‑link selects 3V3 or 5V I/O operations for the Shield 1, Pmod 2, and Pmod 3 interfaces.
One user‑link selects 5V or 12V power for the Shield 0 interface.
One user‑link selects 5V or 12V power for the Shield 1 interface.
Caution
The maximum currents available at the power and reference pins are:
3V3/IOREF 1A maximum available for both Shields and all four Pmod interfaces.
5V/IOREF 1A maximum available for both Shields and all four Pmod interfaces.
12V 0.5A maximum available for both Shields.
