nullbits SNAP 75% Mechanical Keyboard Kit (Black)

The SNAP is a high-quality split 75% keyboard kit with tons of room for customization.
Use the SNAP together, or separate! It snaps together for a traditional 75% layout or pulls apart for use as a split board.
Built around a Pro Micro, rather than a discrete microcontroller. This saves assembly time, and also reduces the build difficulty.
All required parts (diodes, caps, and ICs) are through-hole, meaning they're easy and forgiving to solder.
RGB underglow ready: 10x optional bottom-mounted SMT LEDs shine nicely through the acrylic support material. RGB underglow is supported natively in QMK, allowing for easy programming and configuration.

The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families.
The single wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board.
STM8 applications use the USB full-speed interface to communicate with the ST Visual Develop (STVD) or ST Visual Program (STVP) software..
STM32 applications use the USB full-speed interface to communicate with Atollic, IAR, Keilor TASKING integrated development environments..

AS3935 lightning module can be either powered by an internal voltage regulator or directly by VDD..
GY-AS3935 lightning sensor cannot drive an LCD display on it own. It need a microcontroller, like ESP8266/ESP32 etc.The Microcontroller will control....
If you have any problem, please contact seller as follow: click "DIYmalls"(you can find "Sold by DIYmalls" under Buy Now button), in the new page,....

The NIBBLE is a high-quality 65% keyboard kit with tons of room for customization.
Built around a Pro Micro, rather than a discrete microcontroller. This saves assembly time, and also reduces the build difficulty.
The NIBBLE has more programmable keys than a standard 65%, and allow for multiple layouts.
All required parts (diodes, caps, and ICs) are through-hole, meaning they're easy and forgiving to solder.
RGB underglow ready: 10x optional bottom-mounted SMT LEDs shine nicely through the acrylic support material. RGB underglow is supported natively in QMK, allowing for easy programming and configuration.
