the board

#

the controller...

#

#

#

do all the pins sit inside the mcu?

#

cause he nice nano had two holes open for the battery (b+, b-)

#

That isn't a nice!nano controller though. It is a wired RP2040 controller.

#

correct

#

so do i still leave the top two holes open

#

?

#

i think im supposed to

#

if i fit all the pins into the board holes

#

Bastardkb server might be the appropriate place to inquire, because this is a ZMK server

#

the top two holes are left open like the nice nano

#

oh

#

they dont respond over there

That doesn't really mean that a non-related server would be the right place to ask though. FWIW, pro micro footprint has 2 GND on one edge, and 1 GND on the other edge. Aligning these would be your best guidance. Otherwise, you can exercise patience on the bastardkb server.

#

what do you mean by ground?

#

i see two grounds on the left side of the board

#

and one on the other site

#

side

#

how does that help me in regards to knowing if i should leave the top two pins exposed within a pin through it?

Aligning the GND pins on controller, with GND pins on the PCB helps you with this question. It applies to all PCBs designed to support the pro micro controller.

#

how do i know which is a gnd pin on the pcb?

#

it hard no markings

#

2 GND on one edge, and 1 GND on the other edge
Because of this fact, paying attention to them will avoid installing the controller upside down

#

has

#

hmm

#

how does that help me know which side should be up?

That is why we recommend seeking support at the vendor's discord server, who will be more familiar with the hardware. Otherwise, a multi-meter will also help with this matter.

I believe that bastardkb has some video tutorials where he puts together some keyboards

#

Might apply here

Because if you align the controller's 2 GND pin edge on the PCB side with 1 GND, it will be "wrong"

i didnt buy it from bastardkb its an open source kit loool

But you are still on the wrong server. BastardKB server is still the right place to inquire given their hardware knowledge about the PCB, yes?

true true

#

last q

#

do you know how i can find the ground on the pcb?

#

i have a multimeter

#

do i check for continuity?

long minnow Jul 16, 2024, 2:08 AM

#

Yes, all GND pin will be shorted together

#

@long minnow last q i swear

#

how can i know what pins do what on a microcontroller

#

and where can i find guides on the specific microcontroller...

#

i googled and i cant find the ones for mine

I don't know what this question means. I don't think it is relevant to BKB's PCB. You should be patient on BKB server. Replies are volunteered and not an entitlement.

Did i say it's an entitlement?

Let’s not get argumentative please

I'm trying not to but it doesn't help when someone responds like that.
