Introduction

History

The Elevate is a joint project between me (Gondolindrim), MrKeebs and Tesletron from Framework; I am the PCB designer, MrKeebs is the runner and Tesletron the case designer. Although the case is not open-source, I really wanted to open-source the PCB so I could improve it for next revisions with feedback from the community.

My intention with this board is to make a Bluetooth keyboard, and learning the know-how involved in such technology. This is in order to apply that know how to every other component of the Acheron Project.

The keyboard consists of a 50% bluetooth board, supporting three layouts, among them a split spacebar.

Here’s a list of the board’s features:

• AVR ATMEGA32U4 processor;

• QMK firmware compatible;

• USBC type connector;

• RGB underglow through intelligent integrated controller WS2812B LEDs;

• Three layout support:

• Hardware reset through a push button and reset network;

• Overcurrent and overvoltage input protection through a fuse and schottky diode;

• Case Electrical Static Discharge (ESD) protection through a discharge net;

• ESD protection for the USB connection – GND, VCC and data pins.

• 4-bit DIP switch:

  • Battery on/off control;
  • Bluetooth on/off control;
  • Keyboard on/off control;
  • And a bit connected to the MCU for programmability (changing layouts, for example);

• Bluetooth through a MDBT40 module;

• In switch LEDs;

• Three status indicator LEDs: battery, bluetooth and VCC.
