+# Viktus Styrka
+
+![Styrka](https://i.imgur.com/)
+
+The Viktus Styrka is a 65% + left macro block created in a collaboration of OneCreativeMind and BlindAssassin111 (Viktus owner). All design done by BlindAssassin111. The board supports ANSI and ISO modifiers as well as split backspace and stepped/non-stepped caps lock.
+
+The PCB is an arm powered board utilizing the STM32F072CBT6 mcu. The PCB is designed to work with the universal daughterboard and a 4in (~100mm) 4 pin JST SR cable with reversed pinout (pin 1 of both connectors is the same wire etc.).
+
+On the PCB is a single button for a reset for flashing. As well, there is a [Segger J-Link 6-pin Needle Adapter](https://www.segger.com/products/debug-probes/j-link/accessories/adapters/6-pin-needle-adapter/) footprint for reflashing the mcu as a backup in case of a bootloader issue.
