Yo, this is a 4x4 custom macropad that you can use for making ur life ezz, lol it has 16 macros, 2 rotary encoders, RGB lights and an OLED display. and also it is a successor of my previous macropad Codemate.
whether you are a programmer, 3d modeller, editor or whatever u can easily use this macropad with just a little bit tweak in its firmware.
this is the schematic of the project, which u can see here:
you can see the MCU, the key matrix, the LEDs, encoders, everything in this schematic.
cuz i believe that having a macropad can ezz my workflow and also give make it faster and more efficient.
for this i am using a 2 layer pcb board:
- get the pcb ordered and solder all the components to it carefully
- get these things 3d printed:
- cover it with the top plate
- drill a 2 mm hole near the red holes:
- insert 4 m3 inserts in these holes on the main body.
- Now, put the soldered pcb with all the components inside the main-body
- put the top panel , and put m3 screws.
- now put the keycaps and the knob onto it.
- enjoy <3
written in Arduino framework for ESP32-S3 Zero using these libraries:
- FastLED — RGB control
- Keypad — key matrix
- Adafruit SSD1306 — OLED
- Adafruit PCF8574 — IO expander for encoders
- USB HID (built into ESP32 Arduino core) — keyboard + media keys
- opem Arduino IDE
- add ESP32 board support — paste this in Board Manager URL:
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json - install the libraries above from Library Manager
- select board:
ESP32S3 Dev Module - plug in USB into the devboard
- upload
