Marigold-5 Overview & Safety
Marigold-5 corner view
The Marigold-5 is a synchronous step-down, buck, DC-DC converter module that provides a regulated 5.1V rail for FIRST Robotics Competition applications. It accepts a 6V to 18V input compatible with FRC robots and other power systems and provides power through a high-current USB-C connector and an auxiliary output.
Built around the Texas Instruments TPS56A37, the Marigold-5 provides reliable 5.1V power to co-processors, such as Raspberry Pi and Orange Pi boards, even when input voltage sags.
