Feature:

1. The board has reserved BOOT and RESET buttons. Users can use USB to enter the DFU mode to update firmware

2. Thermistor can select pull-up resistance value through jumper, in this way to support PT1000 (2.2K pull-up resistance), convenient for customers DIY use

3. Onboard 2-way CNC fan, 1 way 4-wire fan interface

4. Proximity switch, CNC fan, 4-wire fan support VIN/12V/5V voltage selection

5. Onboard SPI output interface, this port is reserved with two independent IO ports, which can be used for material cut off, material blocking detection, or DIY operation of other functions

6. Onboard MAX31865, supporting 2-wire / 4-wire PT100/PT1000 option

7. CAN or USB communication is supported. The 120R terminal resistance of CAN CAN be selected through the jumper cap, and CAN ports are reserved for expansion

8. Equipped with DIY terminals, female reeds, double-way studs and screws, which greatly meet customers’ DIY needs
