M01 M.2 2242 E-key Top

Description

52Pi M.2 E-Key HAT M01 provides a 2230/2242 size M.2 E-key expansion slot for the Raspberry Pi 5, making it convenient for users to connect some M.2 E-Key expansion cards, such as the Google Coral Edge TPU or other common wireless network cards, wired network cards, etc.

M01 is compatible with the standard HAT size of Raspberry Pi and supports two sizes of m.2 cards: 2230 and 2242. The included mounting screws make it convenient for users to switch between the two sizes at any time.

Features

• Designed for RPI 5: Dedicated to the latest single-board computer, the Raspberry Pi 5.
• PCIe Support: PCIe x1 interface in both Gen2 & Gen3 standards.
• Hollow design: Hollow design provides excellent ventilation airflow for cooling.
• Camera/Display fpc cutout: The openings in the PCB allow for the routing of two Display/Camera FPC cables.
• Gold-plated PCB: Gold-plated PCBs offer superior electrical performance.
• PCIe ultra-short signal lines: The short trace routing of PCIe is more reliable and faster, fully meeting the signal requirements of PCIe 3.0.
• LED Indicators: Features LED light for M.2 device status.
• Compatible Form Factor: Board format is compatible with the original Raspberry Pi HAT dimensions of 65 x 56.50 mm.
• M.2 Standard-Compliant Power System: Integrated voltage regulator delivering up to 3A for the 3.3V power rail, compliant with M.2 standard.
• All Necessary Accessories Included: Comes with a FPC PCIe ribbon, M2 and M2.5 screws, spacers, and extra custom CNC SSD mount screw.

How to enable PCIex1 functions on Raspberry Pi 5?

• We assume that you are using Raspberry Pi OS (bookwork 64bit) which can be download from the official website: [ https://www.raspberrypi.com/software/ ].

By default, the external PCIe header is not enabled, so to enable it, you can add one of the following options into /boot/config.txt and reboot:

# Enable the PCIe External connector.
dtparam=pciex1

And the connection is certified for Gen 2.0 speed (5 GT/sec), but you can force it to Gen 3.0 (10 GT/sec) if you add the following line after:

dtparam=pciex1_gen=3

• Save it and reboot your Raspberry Pi 5.
