More Raspberry Pi Zero 2 W lookalikes are coming to market, as after the Allwinner H618-based Orange Pi Zero 2W, the Radxa Zero 3W has now been introduced with a 1.6 GHz Rockchip RK3566 processor and up to 8GB RAM, plus WiFi 6 and Bluetooth 5.4 connectivity, which makes it one of the most powerful Arm Linux SBCs in the compact Raspberry Pi Zero form factor.
I've actually just received one of these HATs (the crashing version), and found this issue because my Pi Zero was crashing. Thanks for all the suggestions here.
Instead of messing around with capacitors, wouldn't it be simpler to do this:
remove (clip off / unsolder) the 5V pin(s) from the Pi header
attach the HAT to the Pi
solder a wire from the 3.3v pin to VCC on the HAT
