Description

The PCIe To 2-Ch M.2 HAT+ (B) is an advanced dual-slot storage expansion board built specifically for the Raspberry Pi 5 single-board computer. Designed according to official Raspberry Pi HAT+ guidelines, it incorporates automatic EEPROM recognition for seamless operating system detection.

By leveraging an onboard packet switch chip, the HAT+ (B) manages concurrent communications for two M.2 Key-M NVMe solid-state drives (supporting 2230 and 2242 form factors). Equipped with an embedded power monitoring IC and real-time status LEDs (PWR and ACT), it ensures stable power distribution and visual feedback during high-throughput I/O processes—making it ideal for home servers, local data loggers, and edge computing nodes.

Software & EEPROM Configuration (config.txt)

To enable PCIe Gen 3.0 performance and boot directly from NVMe media on Raspberry Pi OS:

1. Enable PCIe Bus & Gen3 Speed:

   Open /boot/firmware/config.txt and append:

   Plaintext

   dtparam=pciex1
   dtparam=pciex1_no_max_autoprofile
   

2. Configure Boot Order:

   Run sudo rpi-eeprom-config --edit and update:

   Plaintext

   BOOT_ORDER=0xf416
