PM-DC power module datasheet
Overview
The Particle PM-DC power module is a small module that contains:
- 5 - 24VDC 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.

21 | GND | Ground |
22 | GND | Ground |
23 | NC | Leave unconnected (MCU reset on PM-BAT) |
24 | NC | Leave unconnected (power good on PM-BAT) |
25 | ENABLE | Power output enable. Has internal pull-up to VSYS, pull to GND to disable power outputs. |
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.
