The Best 3D printer motherboard for newbies —— BIGTREETECH SKR MINI E3 V2.0

Most 3D printer users have Ender3. However, because Ender3 has been launched for a long time, the stock board may not meet the higher needs of users. For novices who have not replaced 3D printer accessories,  BIGTREETECH SKR Mini E3 V2.0 is the most friendly for novices to update Ender3 motherboard. It is easy to install and easy to use. It also has many upgrades to improve its performance and performance-price ratio. This article will make a comprehensive introduction to  BIGTREETECH SKR Mini E3 V2.0.

Brief introduction

 BIGTREETECH SKR Mini E3 v2.0 is a customized motherboard for Ender3, which is launched by the 3D printing team of Shenzhen Bigtree Technology Co.,Ltd which perfectly replaces the original Ender3 printer motherboard.

The stock board of Ender3 is ATMega12849 of 8-bit AVR, and the built-in Marlin 2.0 firmware occupies a lot of memory, which makes some functions unavailable to users because of insufficient remaining memory.  BIGTREETECH SKR Mini E3 v2.0 is a 32-bit motherboard with ARM Cortex-M3 series chips, which can easily solve these problems and greatly improve the performance of Ender3.

The motherboard uses 4 integrated  BIGTREETECH TMC2209 drivers and increase the distance between the drivers to avoid the problem of heat dissipation. The drivers share the same UART port to improve the stability.

EEPROM AT24C32, more stable data storage, thermistor interface with additional protection devices.

The 5V power supply of bltouch, TFT and RGB interfaces can be selected, and it supports bltouch, filament detection, resumption of printing after power outage and shutdown after the completion of jobs.

Compared with its previous version  BIGTREETECH SKR Mini E3 V1.2,BIGTREETECH SKR Mini E3 V2.0 has been upgraded and optimized in many places. It is a powerful and perfect motherboard, which can greatly improve the user's sense of use. In addition, this motherboard can be used for Ender 3 Pro,Ender 5,CR-10 in addition to replacing the original Ender3 motherboard. Generally speaking, if you are a user of these 3D printers, but you have never change any 3D printer accessories, then  BIGTREETECH SKR Mini E3 V2.0 will be a good start. If you are skilled in replacing 3D printer accessories, this motherboard is also suitable for those who need to upgrade the machine.
