I installed the Pineberry Bottom Hat on my Rasppi 5. When I use the lsblk command the system does not recognize the NVME SSD drive. However, if I use the USB port to connect the NVME card, the system recognizes the NVME SSD Drive. I am using Kali Linux OS.
You might have to ask Pineberry rather than Pimoroni.
However, maybe try updating the RPi firmware and also see if it works with Raspberry Pi OS.
Yes. It worked with Rasp Pi OS on the micro ssd and with Kali Linux installed on the NVMe SSD.
