Hi - ``` I was wondering if anyone has a diagram of the headers on the PyBadge? Adafruit has a brief description that I could find, but I am having trouble knowing what are grounds and what are the corresponding pins for Makecode. I want to be able to provide my students a visual they can use when they start wiring up their PyBadge. Thank you for any help! ``` ---

Here is the Feather spec: [Feather Specification | Introducing Adafruit Feather | Adafruit Learning System](https://learn.adafruit.com/adafruit-feather/feather-specification) A table with the pin labels is toward the bottom of the page. Here is info on the STEMMA connectors: [What is STEMMA? | Adafruit STEMMA & STEMMA QT | Adafruit Learning System](https://learn.adafruit.com/introducing-adafruit-stemma-qt) If you’re still stuck, then just give a holler. ---

I spent some time looking for an answer to this question. It will be interesting to see if anyone offers a diagram to answer it. ---

Once I can wrap my head around it I will create one to share here. ---

Hey Alex - This link was helpful, but I still have a question on which can be used as a ground. I notice there is only one pin for ground and I am hoping some of these other pins can act as ground, so we can attach different inputs to the board. Thank you as always! ---

Hi! If I’m interpreting the photos correctly, then the PyBadge has two connections for each pin in the Feather spec. So, two ground connections, two 3v3 connections, etc. To verify, if you have a multimeter, you can test the 3v3 and ground connections. I don’t own a PyBadge … at least, not yet. I’ve been wanting one for a while, though, and I’ll put it in the budget for next month! If you need additional connections, then you could use a breadboard or a proto board to give you some extra space to build circuits. I’ve linked a couple of products below that may be helpful. - [FeatherWing Proto - Prototyping Add-on For All Feather Boards : ID 2884 : $4.95 : Adafruit Industries, Unique & fun DIY electronics and kits](https://www.adafruit.com/product/2884) - [Assembled Terminal Block Breakout FeatherWing for all Feathers : ID 2926 : $14.95 : Adafruit Industries, Unique & fun DIY electronics and kits](https://www.adafruit.com/product/2926)
