Power a TTGO with an 18650 shield?

[Winfried]

Hello,

I know nothing about electronics.

I ordered https://www.aliexpress.com/item/4001113579534.html to power a https://www.aliexpress.com/item/33048962331.html and get rid of the power bank I currently use.

1. Can the TTGO actually be powered by this shield, and if yes, through which pin? The 5V pin?

2. I then need to power a sensor, which requires 5V. As shown, the TTGO only has a single 5V output: Should I solder both the shield and the sensor to the 5V pin?

Thank you.

The documentation and the circuit for this board are available here - https://github.com/Xinyuan-LilyGO/TTGO-T-Display

As per the circuit diagram, you can power your TTGO T-Display using the battery shield. The TTGO TDisplay has an internal voltage regulator that converts the 5V to 3V3. The connections you have planned are correct.

But Im not sure if you can use both USB and external 5V at the same time. Better to get this confirmed by TTGO. Just disconnect the battery shield when USB is connected during programming.
