DuinoTech Arduino Compatible Linker Base Shield – Marked 2.54mm Headers, SPI / IIC / UART

Breadboards get fiddly. Wires fall out mid-build. You lose twenty minutes chasing a loose connection on pin 13. The Linker Base Shield kills that frustration. Clearly marked 2.54mm headers replace the confusing I/O pin layout, so you plug in your modules and they stay put. One SPI, two IIC, one UART – all labelled where you can actually see them. Built for people who want to build without fighting their board every single time

• Clearly marked 2.54mm headers replace standard I/O pins
• Connections: 1× SPI, 2× IIC, 1× UART – all labelled
• Easier than breadboard or protoboard for repeatable builds
• Arduino compatible – stacks directly on your board
• Ideal for starters moving beyond jumper-wire chaos
