M5stack 5V Buck Converter Unit(ME3116AM6G)

Description

This 5V buck converter is a compact Unit Power supply module built around the ME3116AM6G DC-DC step-down chip. It accepts a DC 6-24V input and provides a stable 5V/1A output for embedded 5V loads, making it useful when a project needs a small regulated supply from a common DC adapter.

The 5V buck converter uses a DC-015 barrel jack on the input side and an HY2.0-4P Grove output connector on the 5V side. The connector layout keeps wiring simple for Grove-compatible controllers, sensor hubs, small test fixtures, and other electronics that need a dependable 5V rail.

Because the module includes a red power indicator and plug-and-play wiring, it is easy to check input power during assembly. For compact controller builds, the Unit Power module helps convert a wider adapter input into the 5V supply needed by many embedded devices.

Other Content

Before using the 5V buck converter, confirm that the input adapter is within the DC 6-24V range and that the connected device load does not exceed the 5V/1A output capability. The red indicator helps confirm that the module is powered before the downstream circuit is connected.

The HY2.0-4P output follows the Unit Power pin mapping: black wire is GND, red wire is 5V, and the yellow and white signal positions are not connected. This makes the module suitable for power-only Grove wiring where data lines are not required.

FAQ

What is this 5V buck converter used for?

It converts a DC 6-24V adapter input into a regulated 5V/1A output for embedded devices, Grove wiring, controller projects, and other compact electronics.

Can it power any 5V device?

It can power 5V devices as long as the load stays within the 1A output capability and the input source stays inside the supported DC voltage range.

Which connector is used for output?

The output side uses an HY2.0-4P Grove connector. On the pin map, black is GND, red is 5V, and the yellow and white positions are not connected.

Does the module show power status?

Yes. A red LED indicates power status, which is helpful when checking adapter input and wiring during setup.
