 ## Variants / branches
 
-### Legacy
+### [Legacy](https://code.electrolab.fr/Flax/solderstationmk2_hw/-/tree/Legacy)
 
 Based on the original hardware from F6ITU, re-created in Kicad 7.0 from the ground up. This variant aims at being as close as possible to the original design, with integration of the corrections on equipped board.
 
-### Flax_variant
+### [Flax_variant](https://code.electrolab.fr/Flax/solderstationmk2_hw/-/tree/Flax_variant)
 
 Single PCB, smaller 7 segment display, additional I²C connector for eventual extensions, designed for use with ST Nucleo STM32L011K4.
 
-### PIC_variant
+### [PICLight_variant](https://code.electrolab.fr/Flax/solderstationmk2_hw/-/tree/PICLight_variant)
 
 Single PCB, no 7-segment display, no encoder, temperature set with single potentiometer, based on PIC12F1572, double implantatio for SMD and through-hole components.
 
-### PIC_variant_THT
+### [PICLight_THT_variant](https://code.electrolab.fr/Flax/solderstationmk2_hw/-/tree/PICLight_THT_variant)
 
 Same as PIC_variant, only through-hole components present, aligned on 2.54mm grid for easier manual building on veroboard.
