I've been doing some reading about how to connect a bunch of teensies together, but the forum posts I've found have either been for different devices or very outdated based on the use of old USB technology.
I have a macbook pro 2019 16 inch, which has 4 thunderbolt 3 ports. As far as I can tell, these ports support 15V at 5W for a total of 3amps each.
I have a teensy 4.1 with a bunch of different types of sensors attached with its own dedicated thunderbolt port on the macbook pro. I would also like to leave 1 thunderbolt port empty. This leaves 2 available thunderbolt ports.
Goal: power 5 more teensy 4.1s through the same macbook pro. Each of these teensies would be exclusively dedicated to reading a single capacitive proximity sensor and sending the output to the main teensy 4.1 (above).
I would like to achieve this by powering these teensies with a single thunderbolt port if possible, otherwise 2 ports is okay. None of the teensies would be overclocked, so they'd be running around 100mA. They do not need to be able to serially communicate with the laptop, just need power.
Would any of these options work? (ranked in order of my preference)
1) plugging in 1 of the 5 teensies to the laptop thunderbolt port, then connecting the daisy chaining the remaining 4 teensies in series by plugging in the Vin and GND of the 2nd teensy to the 1st, of the 3rd teensy to the 2nd, and so on. My concern is this would surpass the max current that can be handled by teensy 4.1
2) plugging in a usb hub (something like the TP-LINK 7 port UH720 Hub 7 x SuperSpeed USB 3.0 desktop) to the thunderbolt port on the macbook and plugging in each of the 5 teensies individually through their own usb cables to the hub. Critically, I do not want to use a powered hub, only something that draws power just from the macbook pro.
3) Using a nonpowered hub for each of two thunderbolt ports and plugging in 3 teensies to one and 2 teensies to the other.
If none of these options work, would I be able to make one of them work if I used teensy 3.2s instead? (draw max 50mA each)
Thanks!
