I'm designing a dev board to test out NeoPixel (both SK6805-EC15 and SK6805-EC20). The goal is to power it off a 3V battery (CR2032) and have the MCU be a low ram chip (STM32C0).

The SK6805 need 5V so I have both a boost power supply (TPS610997YFFR) and level shifter (SN74LVC1T45DBVR).

I'm guessing the battery might be insufficient so I have a jumper to disconnect the battery if needed.

I'm going to have the boards made at JLCPCB

Any suggestions? Thanks in advance
