How to power Coral edge-tpu dev-board off a battery
I bought a google Edge TPU Coral dev board (https://coral.ai/products/dev-board/). It’s an amazing device and I would like to include it in a robotics project. However: I was wondering how I should power it if it can’t be connected to a wall-socket. I thought of the following options:
- Connect it to a USB-C powerbank. Easy choice, but I don’t have any
- Connect it to a normal powerbank with a USB->USB-C converter. I was wondering if this can damage the board in any way
- Connect it to a LIPO battery with a 5V BEC. I looked at the data sheet and couldn’t find a specific place to attach my own power source outside of the USB-C input. Is there any way to accomplish this feat?
Thanks in advance :)
Solution
To answer my own question: I decided to be brave and just try it out. Here you see a 5V power bank with normal USB output, a USB -> USB micro cable, and a usb-micro to usb-c adapter. This could power the coral dev board, it booted, and I could ssh to it (although I guess it would be good to look at the power draw when running heavy neural network inferencing).
