Triple-mode RGB Logitech G613 transplantation board

In terms of main control,
the wireless main control adopts Logitech G613 main control, which has one of the most stable wireless modes in the industry - Lightspeed, which is power-saving and stable, and is responsible for providing Bluetooth and 2.4G functions.
The wired main control uses APM32F103CBT6, which can replace STM32. The individual purchase price is around 5 yuan, which is suitable for individual enthusiasts to develop and try out. Wired power supply and light power supply can be completely turned off. When no analog switch is added to realize the FN function, the power consumption is not substantially different from the original G613.
Functionally,
the open source QMK firmware is used.
The main control board integrates almost all components including the encoder circuit. The basic functions can be realized by adding only the battery interface, switch interface, USB interface, diode, and RGB light to the large board. The FN function in wireless mode can be implemented by adding an analog switch (power consumption will increase).
Logitech GHUB software can be used, while retaining the 6 G keys of G613 and can be customized.
RGB, solenoid valve, and buzzer can be used in wired and wireless modes and can be turned on at the same time.
The OLED screen and encoder functions (now available in wired mode) can be developed by yourself, welcome to communicate.
Array replacement
adopts the main control board separation design, which leads to all matrices of G613. You can edit and build keyboards of various sizes by yourself, and just modify the lighting matrix.
The G613 main control can choose not to be welded. At this time, it is a wired QMK keyboard, and all other functions except wireless mode are retained. Convenient for personal choice. There is a five-key RGB HUB circuit in
the HUB
project for physical verification. The keyboard part firmware can be modified according to the QMK source code. You can use it yourself.
To flash the firmware
, please decompress the firmware source code and transfer it to the official QMK sample folder for firmware compilation. After flashing the BL and firmware, it can be used.
The shell
express is blocked and temporarily unavailable.
Notes
1. Please limit the maximum RGB brightness in the firmware. Otherwise, when there is no battery power supply and only uses the computer USB power supply, the lights will seize the main control power supply and make the keyboard unresponsive. There is no such problem when using batteries.
2. The maximum battery discharge current is 2.4A. Using the solenoid valve when RGB reaches maximum brightness may cause the solenoid valve current to be too small to be used. Please reduce the RGB brightness or use USB and battery power supply at the same time.
When plugging in USB to charge the battery, please turn off wired mode, as it may not charge properly.
3. The pads at the fixing screws of the M2 small board are reserved for SMT patch studs. Please modify the size according to the size you purchased.
