wlpuah / RUMBA32 - History

v1.0B fixes

- Remap HEATER_BED_PIN to PWM capable pin
- Remap FAN_PIN to PWM capable pin
- Tidy labeling of stepper driver jumpers
- Change stepper driver voltage jumper to default to 3V (as per schematic)
- Add back in MOSFET driver voltage select, default to 5V
- Move 5V regulator voltage sense trace away from noise source under regulator IC
- Add pads for optional I2C EEPROM
- Add SMD test points for three unused STM32F4 pins
- General tidying of schematic and PCB routing

Update to v1.0B

Change bed MOSFET to BUK9Y4R4-40E
Remove jumper to select bed MOSFET driver voltage source, hardwired to 5V (BUK9Y4R4-40E has +/- 10V as maximum VGS, so 12V could be damaging).

Update README.md

Fix schematic image

Routing Done

Routing work finished and PCB tentatively ready for prototyping. Several schematic changes - mostly microcontroller pinout, but also changes to 12V regulator.

Ongoing PCB Work

Mainly power supply work

Initial PCB work

Remove unneeded components, clear back traces to microcontroller, ready to start layout work
