LiPO SHIM - Raspberry Pi Forums
hi there.
have purchased lipo shim.
have soldered female header on , followed instructions use pimoroni 1 line code , installed it.i enabled pin 4 power off.
when turn on pi shim fitted starts turns off instantly.
if remove shim pi boots normally.
have not got battery yet can not test it. because there no battery correct voltage reason pi switches off?
there setting can use pi adapter shim fitted or have done wrong.
regards paul

let me see ...
one-liner shuts pi down when gpio 4 pulled low.
lipo shim designed pull gpio 4 low when battery voltage low.
without battery, shim detect low battery.
