Product description: Bigtreetech SKR 2 motherboard for 3D printers
Bigtreetech SKR 2 is a motherboard based on 32-bit STM32F407VGT6 microcontroller with ARM Cortex-M4 core. It is used in the Biqu B1 3D printer, among others. As firmware it can use Marlin as well as RepRap solutions. On the controller there is WiFi interface compatible with ESP-12S and ESP-07S modules. Bigtreetech SKR 2 allows to connect two types of displays: traditional 12864 LCD or touchscreen using SPI bus.
