Mks-Sbase

The MKS-SBASE has a level shifter in the SPI circuit and therefore the EXP1 connector cannot be used. However adding an onboard jumper allows the J7 header to be used instead. Solder a jumper between pin 4 on U11 to pin 2 on the J7 header.

Firmware and Config

  • Firmware for the MKS-SBASE is LPC1768

In your .hal file, you will need to configure the Remora chip_type to “LPC”

loadrt remora_lpc chip_type=LPC

Hardware Pins

Remora firmware has some features available only on specific hardware pins.

Available PWM Hardware pins:

  • 2.0, 2.5, 1.18, 1.20, 1.21, 1.23, 1.24, 1.26, 3.25, 3.26

Available QEI Encoder Hardware pins:

  • 1.20

  • 1.23

  • 1.24 is used as index

Wiring

Wiring requires the following components:

  • 100mm Female-Female Dupont ribbon jumper

  • 6 way (1x6) Dupont connector

  • 8 way (2x4) Dupont connector

  • 1 way Dupont connector
