README
readme.mdXT30 Power Module
A "power brick" for ArduPilot/Pixhawk/PX4 systems, with XT30 power connectors and digital voltage/current measurement.
Overview
This project contains the PCB design files for an XT30 power module, designed using KiCad 8.0. The module provides power measurement and 5V flight controller power.
For power measurement, the INA219 sensor was used due to it's more reliable readings at low current levels (<5A), making it suitable for low-power vehicles, such as ground rovers.
Max Ratings: -Max voltage 17V -Max current 15A
The power module supplies 5.2V at up to 2.5A.
The KiCAD files contain JLCPCB part ID's (LCSC) for easy manufacturing at JLCPCB.
The JST-GH connectors are standard Pixhawk power and i2c connectors (https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-009%20Pixhawk%20Connector%20Standard.pdf), and will plug straight into most flight controllers.

ArduPilot configuration
Due to a digital I2C power measurement IC being used, the power module has a 2nd connector to the I2C port on the flight controller.
In ArduPilot, ensure the BATTx_MONITOR parameter is set to INA2XX and BATT_I2C_ADDR to 64,
and then reboot.
Testing
This board has been successfully used on several 3S ground rovers using the latest version of ArduPilot.

Questions
How big is the XT30PowerV2 PCB?
It measures 46.3 × 17.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the XT30PowerV2 use?
18 parts, built around the CRCW040210K0FKEDC, GRM21BR61E106MA73L, CRCW040259K0FKEDC and SM04B-GHS-TB(LF)(SN). The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the XT30PowerV2 KiCad files?
From the stephendade/XT30PowerModule repository on GitHub, at the commit this page was made from: the board is XT30PowerV2.kicad_pcb and its schematic XT30PowerV2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the XT30PowerV2 design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
