Re: Alpha 864 power adapter connection cannot be powered on, unable to boot.

I'd suggest buying one each - UM25C (this is USB power meter, supporting USB type-C IN and OUT) and - USB type-C to USB type-C cable Use that to measure if USB type-C PD function is behaving normally. I think LattePanda should make a DC power cord for sale: one end is the 4-pin PH2.0 JST male connec...

Re: Connectors of display and touchscreen.

What is the current sourcing capability on the 3.3V rail (if getting the power feed from the 0.1" pitch DuPont connectors)?

(Natually not getting the power from the 30pin 0.5mm pitch FPC cable.)

Thanks!

Re: L.P. Alpha DC power experiments and observations

Now that I have some time to start playing with both Linux and Windows, including adding load (benchmarking, playing video, etc.) I don't feel confident to run LPA864 on just 12V 1.5A power supply, unless I know the workload will ALWAYS be low. 12V 2A will be very marginal and IMO minimum requiremen...

Unknown LP Alpha connectors

Hi, There is a white 10-pin white-colored low-profile connector on the back side of LattePanda Alpha. It's on the long side of the PCB and is on the same side of the Intel WiFi Module. (not on the flat panel display/touch FPC connectors side) What is it used for? Also, there is a two-pin "SW" connec...

Re: WD Blue M.2 is work well LattePanda Alpha?

@ vnlevanduoc That pic is mPCIe slot. Not to be confused with M.2 slot. How many external SATA drives you need to connect to? There are M.2 SATA interface cards. Simple/inexpensive one (no active electronics) support one regular SATA drive. There is an Innodisk SATA adapter that can support 2 SATA d...

Re: WD Blue M.2 is work well LattePanda Alpha?

Latte Panda Alpha has the M.2 M-Key slot which has 4-lane PCIe bus capability. It can accommodate ordinary M.2 NVMe SSD, for example Samsung 970 EVO 250GB - NVMe PCIe M.2 2280 SSD (MZ-V7E250BW) It can also the regular/quite-common/cheap M.2 SATA SSD, for example WD Blue 3D NAND 500GB PC SSD - SATA I...
