BIGTREETECH SKR MINI E3 V3.0 3D Motherboard TMC2209 3D Printer Parts For Ender 3 Upgrade Ender 3 V2 BTT SKR V1.4 Turbo Octopus

Introduction：

SKR MINI E3 V3.0 is an upgraded version of V2.0, which has the following features:

1. New ID design upgrade

2. G0 series MCU- STM32G0B1RET6

3. Heat sink design upgrade, increase the heat dissipation area, greatly improve the heat dissipation performance

4. Increase the fan that can control the heat dissipation of the device to lower the temperature of the device

5. Increase the thermistor interface protection circuit to prevent burning of the master control chip
