PM-DC power module datasheet

Overview

The Particle PM-DC power module is a small module that contains:

• 5 - 12VDC input
• 3.3V regulated output for MCU (1A)
• 4.0V output for cellular modem (2.5A)

It can either be:

• A castellated module intended to be reflow soldered to your M.2 SoM base board
• A module with male pins on the bottom that can be plugged into a socket on your M.2 SoM base board

The PM-BAT power module is also available if you would like support for a LiPo battery as well as DC input.

Dimensions

Dimensions in mm

• Module is 35mm x 22.86mm (1.38" x 0.9")
• Pins and castellated holes are 2.54mm (0.1") apart

Pinout

3V3_AUX is powered by 3V3 via a load switch (TPS22918). It can supply up to the full 2A of 3V3. It defaults to off due to a pull-down resistor on the pin. Pull to 3V3 to enable the 3V3_AUX output.

If your base board is designed for the PM-BAT power module, you can substitute the PM-DC and the PM-DC power module will function properly, but features such as power management, battery input, charge LED, etc. will not be available, of course.

Pin layout

Dimensions in mm

• Male header pins are 0.1" spacing, 12 or 13 pins per side
• Two rows, spaced 0.8" (20.32mm) apart

The mating header is available from a large number of suppliers in both PTH and SMD styles.
