✓✔ 【DIY Soldering Practice Kit & Functional Mechanical Numeric Keypad】 Build your own 17-key mechanical numeric keypad with this hands-on soldering project kit. The kit includes two SMD components (USB interface and chip) for surface-mount soldering practice, while the remaining components are through-hole parts for assembly. After soldering and assembly, you get a functional USB numeric keypad for daily data entry, spreadsheets, programming, and other applications.
✓✔ 【Hot-Swappable Blue Switches & Removable Keycaps】 Equipped with blue mechanical switches that provide a clicky typing feel and tactile feedback. The hot-swappable design supports standard 3-pin and 5-pin mechanical switches, allowing switches to be replaced without soldering. The removable keycaps feature an ergonomic curved profile for comfortable typing, and the white minimalist design fits various desktop setups.
✓✔ 【Plug & Play USB Numeric Keypad for Windows】 Connect the assembled keypad to a Windows PC with the included USB cable and start using it directly without additional drivers or software.
