# Bat-Board
Bat-Board is a 12 key macropad with an OLED Display. It uses QMK firmware, easy to use and customize macro
I tried to make a multipupose and multi layer macropad. 1 layer for 1 purpose. I tried to make somthing like adafruit or protodesigns macropad. It will work like them but need a better case more like acrylic. I have used all of this first time. It was fun somtimes and sometimes frustrating. If think i need to add a stand like system in the case but building it is a liitle hard for me.
## Features:
- Multilayer Functionality.
- 128x32 OLED Display
- First key for main controller or for whatever you want
- 12 Keys
## PCB
Here's my PCB! It was made in KiCad. I was thing of using a silkscreen but didn't like anything .
Schematic
- [Schematics](/PCB/Macropad_Schematics.pdf)
I used MX_V2 for the keyswitch footprints. I think in retrospect, I should've added a ground plane
## Firmware Overview
This hackpad uses [QMK](https://qmk.fm/) firmware for everything.
- The main left button is for contol purpose works as togle and to switch between layers and more. More like ctrl button of keyboard
- Last 4 white keys will be the arrow keys of keyboard. Other keys are custom set macros and links.
- The OLED is Not decided yet but i am thing of something from naruto or demon slayer
I might add more in the future! That's it for now
## BOM:
Here should be everything you need to make this hackpad
- 13x Cherry MX Switches
- 4x SK6812 MINI Leds
- 1x XIAO RP2040
- 4x Blank DSA Keycaps
- 9x M3x16 Bolt
- 9x M3 Heatset
- 1x 0.91" 128x32 OLED Display
- 13x Through-hole 1N4148 Diodes
- 1x Red Blank DSA keycaps
- 4x White Blank DSA keycaps
- 9x Black Blank DSA keycaps
- 9x M3 hex nuts
Extras:-
- Few Jump Wires
- Breadboard
For testing before placing
Others:
- KMK Firmware
- Top Case.stl
- Bottom Case.stl
