Pi4, ClusterHAT, FanSHIM, etc. NOT included.
Keep the 3.3v rail alive between reboots.
When rebooting a Raspberry Pi 4 the 3.3 volt rail is reset which causes problems for some HATs.
3v3 Sustain fits in between a Raspberry Pi and a HAT/pHAT and provides a stable 3.3 volts (300 mA max) during reboots.
It also has a cutout to help keep the Pi 4 cooler (can be used with the Pimoroni FanSHIM, etc.).
Included
- Pre-soldered 3v3 Sustain PCB
- 4x 12mm M2.5 spacers
- 8x 6mm M2.5 screws
