Disclaimer: I am not an electronics engineer or expert. This diagram represents my personal setup and what worked for me. The intention is to ensure a minimum of 144 pixels due to the LED image definition, rechargeability, and a runtime of at least 2 hours. I invite the community to improve the design to work with the same OpenHoop Arduino Nano 33 BLE project and Adafruit NeoPixel LED density.
