"Black pill" board?

Postby Kenjutsu » Wed Nov 09, 2016 7:03 am

Hello everyone,

Has anyone seen/used this board before?

At first glance, it looks like a "black" Blue Pill board. For port A and B, it has the same pins brought out, but for port C, only PC13, which I can only assume is for the on-board LED. It also has less gnd and 3V3 pins and no 5V and VBat. For the price, I am quite tempted to buy 5. Seeing that this board is so close to the Blue Pill board, I assume it should work?

Thank you

it has already extensively been discussed in the bluepill vs redpill thread

Thank you, I think I will give it a skip for now ;)

Yes. It works

I have one of them.

I build a bootloader for its config (LED is not on same pin as the Blue Pill)

I have been using many regular Blue Pill boards from various sellers, so I guess any of the following?

Just for cross referencing, the Black Pill was discussed in the Blue Pill Red Pill thread, here viewtopic.php?f=28&t=117&p=19277&hilit=black+pill#p19277

I have not had time to look at the Black Pill in detail, but it does have a stronger USB connector than the Blue Pill, which is an advanAge, but the PCB is bigger and wider, and leaves less space around it in a breadboard.

I dont recall what the USB pullup resistor value is, but it worked for me without modification

My Black Pill just arrived. The LED is attached to PB12, not PC13 as with the Blue Pill (at least on my board). There is now a wiki page for the board. It also comes with the correct 1.5 kohm pullup on PA12 so the USB works, in my opinion that makes it better than the Blue Pill.

Benji

I have one of them as well, and it worked fine. Its also better than the Blue Pill because the USB connector is much stronger.

The Blue (and Red) Pill have very cheap USB connectors which often break off the top of the PCB as they are only secured by a couple of small PCB pads. The Black Pill has through hole fixings on the USB connector, making it a lot stronger

I believe I may have found the schematic for the black pill. If so it can be added to the wiki. My boards are on order, so I can't verify that this is the right drawing. The 1.5k USB resistor is shown on the schematic as R7. Schematic is here.
