This is the first public release of the HelloWord smart keyboard.

IPOPULAR is the exclusive partner for this launch event.

The HelloWord 75 (Hanwen 75) mechanical keyboard is a Lego-structured mechanical keyboard. The keyboard uses independent module combinations. There is a multi-functional scene interaction module on the left that can replace various custom components. By default, it uses dynamic components with an e-ink screen and FOC force feedback knob. It uses keyboard firmware and module firmware based on the ARM Cortex-M chip. The keyboard body uses shift registers to achieve optimized key scanning circuits. Modules and keyboard bodies can be used independently or communicate and call each other through a serial protocol.
