一、主板简介
BTT SKR E3 Turbois a customized motherboard for Ender3 printer
launched by the 3D printing team of
Shenzhen BIGTREE technology
co., LTD., which can perfectly replace the motherboard of the original
Ender3 printer.
1.
Motherboard features:
1） Use SGM6130 power chip, support 12-24V power input, power
conversion rate up to 94%, maximum output current up to 2.5A;
2）The hot bed MOS tube uses WSK220N04, low on-resistance, larger
heat dissipation area, and reduce heat generation;
3）Onboard Sensorless homing function, which can be used by
plugging in the jump cap；
4）Optimize the plate and frame to avoid the phenomenon of screw
hole gap and screws hitting components;
5）Support BLtouch, filament detection, power-off resume,
automatic shutdown, etc
6）Onboard EEPROM: AT24C32;
7）Add parallel double Z-axis interface;
8）Increase the board layer: 4 layer board;
9）Increase the heat dissipation area of the back driver and
strengthen the heat dissipation capacity;
10） Two CNC fan interfaces；
11）Increase the distance between the driving chip and the
components to avoid the trouble caused by the heat sink;
12）Add protection device to the thermistor interface;
13） 5V power supply with BLtouch, TFT and RGB interfaces is
optional;
14）The USB port adopts the ESD protector USBLC6-2, which
effectively protects the USB port from damage;
15）The main control adopts LPC1769 chip, the main frequency is
up to 120MHz, and the ARM-level Cortex-M3;
16）5 TMC2209 drivers on board, supporting dual extruders;
17）Onboard NTC100K thermistor, real-time monitoring of
motherboard temperature;
18）Adding the Standby function of TMC2209, customers can change
the firmware according to their personal needs,Set the Standby
function. In this mode, the drive chip will automatically cut off
