FYSETC S6 V2.1 motherboard

The FYSETC S6 board is based on the STM32F446 32-bit microprocessor and, like the F6, has six drive slots and supports the full range of TMC drives. During the design of the S6, possible scenarios for the use of 3D printers were considered and a number of extended applications were implemented, such as a counter-rotating circuit, 12V power supply, thermocouple support, 24V sensor support.

Technical specifications:

• Compact size: 117mm x 87mm, same as F6
• Based on STM32F446 180 MHz, all ICs are capable of withstanding 5V
• Support for 6-stage TMC drivers, no need for wired Uart/SPI
• Improved TMC jumper settings, simpler and easier to understand
• Main reverse power protection circuit, safer
• Input voltage max. 28 V, 12 V at 5 A, 5 V with 2ADC-DC circuit, 3.3 V at 0.6 A LDO
• Two automotive fuses to connect heated pad and main power input.
• 24V/5V/3.3V limit switch connector is optional, ready for other devices such as inductive sensor, BL-Touch
• 10 power mosfet outputs with PWM support (1 for HotBed, 3 for Heat-End, 3 for fans, 3 for RGB LED strips)
• 3-pin temperature connector, thermistor or thermocouple can be used (requires AD597 module)
• 3-pin connector for PWM fans, 2-way RGB LEDs, optional 12V and 24V
