MACROPAD RP2040 Bare Bones - keyboard module with LED backlight, encoder and display

Description

Mechanical keyboard module based on the RP2040 microcontroller. Equipped with Cherry MX compatible switch sockets (no switches and sockets included). On the board, the user has an encoder, buzzer and OLED display with a resolution of 128x64 px, communicating via the SPI interface. Each of the buttons is illuminated by the RGB NeoPixel diode, and additional sensors can be connected thanks to the STEMMA QT connector. The module is controlled by the RP2040 microcontroller, which has two ARM Cortex M0 + cores operating at a frequency of 133 MHz, 264 KB of RAM and 30 GPIO ports. The microcontroller is not equipped with flash memory, but on the board there is an external memory with a capacity of 8 MB connected via the QSPI interface. Can be programmed in C/C++, CircuitPython or MicroPython. Full documentation and examples of use are available on the product page.
