Swirly Grid
Connect one STEMMA QT cable to the Feather before fastening it to the swirly grid, since the port will be hard to access afterwards.
Fasten the Feather to the grid as shown using M2.5 x 12mm F-F hex standoffs and short screws.
Mount the breakout boards with M2.5 x 6mm F-F standoffs as shown.
Connections
The Power Deliverer is assembled without any soldering. Plugging in STEMMA QT cables and screwing in wires to terminal blocks is all that's required.
Follow the Fritzing diagram above to see how it all goes together.
First, plug a STEMMA QT cable from the Feather to the INA219 board.
A second STEMMA QT cable connects the INA219 to the HUSB238 Power Delivery Dummy.
To measure current, the INA219 is connected between the HUSB238 and the DC powered device you're running:
- HUSB238 V+ to INA219 V-
- INA219 V+ to DC output V+
- HUSB238 GND to DC output GND
The output DC power socket is the female half of the waterproof DC power cable set which can either run out of the case freely or be zip-tied to the swirly grid as shown.
The case was designed so the 10x2 swirly grid snap fits into the base. There are cutouts for the two USB C ports, the DC power line, and the TFT display.
Four push tabs can be used to press the Feather's buttons.
Download the STL model linked below to print on an FDM printer. You can use the STEP file as a launching off point for modifications and remixes.
Snap Into Place
Feed the Power Deliverer into the case as shown, making sure to line up the ports with the holes.
