Ahoy Pirates. First post & first Pimoroni product,
I bought a Pimoroni Pan-Tilt HAT for Raspberry Pi - without pan-tilt module from Adafruit and am unsure how to wire/portable-power it for use on my robot. I’ll be adding an assembled pan tilt arm w/servos (https://www.adafruit.com/product/1967) and a Pi cam to the Pan-tilt Hat. The hat will be on stackable headers on an Adafruit Motor Hat that’s on a Pi 3 B+. Robot and control app are so far working well but I need help with Pan-Tilt
The page for the Pan-Tilt HAT mentions using a high quality 5v/2.4A power supply, but (image here from Adafruit site https://cdn-shop.adafruit.com/1200x900/3353-00.jpg) 1) there aren’t any jacks on the Hat, and 2) I’m unsure what would be the best portable power options for the Pan-Tilt hat (despite building the bot and coding the app I’m REALLY GREEN to even basic electronics so kindly be very explicit, I have no training in electronics at all, just started making a few months ago).
So sorry for the engineering n00b questions, but:
- Can I solder something into the pins in the diagram, then use another 3350mAh cell-phone charger to power this hat and it’s motors? If so, what kind of jack would I attach and where would it go?
- Should I instead solder power from a separate 4AA (or 6AA with rechargables) directly to the Pan-Tilt Hat and if so, where do red and black wires go?
- If I go with option 2 - can I put a terminal or jack over location where I attach power so that I have more flexibility in swapping out power?
- Are the three separate battery packs (one for pi and one for each hat) the right way to be thinking about this project, or is there a preferable way to unify these with a beefier battery option I can somehow use across the two hats or even all three boards (Pi 3B+, Adafruit Motor Hat, and Pimoni Pan-Tilt Hat)?
I’ve shared some tutorial videos on what I’ve built so far (iOS to Pi uses MQTT, mosquito on Pi, and a simple python script on the Pi). For a look, see:
Thx for advice!
