Mini or micro USB for D1 board?

Hi, I just ordered by mistake, the wrong cable for my Wemos D1 board.

Can someone please advise what cable I need to go from laptop USP to Wemos D1 board? USB to USB mini, or USB to USB micro....????

A weblink would help also. Thank You !!!

To avoid confusion please post a link to the board that you have ordered

This is what i ordered and received...but the end is too big for the wemos d1 board.

Could we have a photo of the board?

But @seniorcitizenhere did not say mini.

@UKHeliBob asked for a link to the board so we can know if it is a mini or a D1 R2 (Uno Size).

Unfortunately @seniorcitizenhere posted a link to the cable, which we already know is unsuitable.

But it does tell us that micro-USB does not fit. To my knowledge, almost all Wemos D1 boards, even the D1 R2, use micro-USB. Never saw one with USB-mini or full-size USB-B like Uno.

But some of the newest Wemos boards use USB-C.

Oops my bad.
But pictures will help to.

Here's the D1 mini that I have installed in my project; also here's a D1 (not mini) that I also own. The cable I have fits BOTH boards, and that's the cable I need to buy (but I need a short cable). They do sell 6" which is perfect for me, but I just don't know what type cable to order.

oops. when i typed this I couldn't see HOW to attach a photo (don't see the attach paperclip, etc)

How about just the link?


New forum members cannot attach photos until they have read/posted a few times.


From this angle it looks like a micro usb.
But it could be a micro b usb.
Photos from different angle?


heres a photo of the Cable I have and the end of the D1 board(not the mini board...although same connector)

Hopefully ??? this photo will help show better what I have....hence what I am looking to buy
This cable fits bot boards

Standard D1 and D1 mini. Micro-USB should fit.

Can you show close-up end-on photo of your old cable and new cable together?

the smaller one on the LEFT is what fits. The one on the Right is what I ordered by mistake.

I dont know whether the one on the LEFT is a mini or micro end?

Left is a micro-USB

Right is a USB-C. You were sent wrong item.

Unfortunately I ordered the wrong cable, and they shipped what I mistakenly ordered.

so what is the correct one on the LEFT ? That's what I need to order now

See post #16

And see USB hardware - Wikipedia

THANK YOU SO MUCH. (I just read the bottom of your #16 reply....and didn't notice the top...)

Now I know what to order. This forum is a lifesaver for sure.

Strictly speaking, it's a micro-b USB. Apparently there is also a micro-a USB. Never seen one of those in the flesh myself.

USB-C (not same scale as above):
