What type of the PCIe connector is on HummingBoard-T-AM64x?

Hi,
I only read some documents about TI AM64X and that development board. A type of the PCIe connector is M.2 on the HummingBoard-T . But, mini PCIe connector mounted on the LTE Modem (Quectel EC25) in the TI AM64X-Evalution Kit. The both connector type are not same isn’t it? How to conect the LTE modem and the HummingBoard?

It is why, I will have a WiFi module that have M.2 E-key PCIe connector. Can I mount it on the HummingBoard, and can I use it with no probrem?
Thanks,

AM64 HummingBoard-T has two M.2 connectors:

  1. E-Key (labeled on PCB “M1”) for PCI-E
  2. B-Key (labeled on PCB “M2”) for USB-3.0

We have successfully tested two wifi modules on the first connector:

  • QCNFA222
  • 8260NGW

Note USB-3.0 and PCI-E are mutually exclusive, only one is usable at a time.
Note also mounting cards on both connectors at same time is not recommended due to limited power budget and mounting difficulties with the fixation screw.

Hi,Josua
Thank you for the reply.
I see a specification of the AM64 HummingBoard, that has M.2 connectors.

I had miss understand the type of the connectors, because there is a LTE Modem with mini-PCI connector on the web page “TI AM64X SITARA SYSTEM ON MODULE”.
