I believe after #76e391446151732316c39055638c21bfe2827c88 the heater MOSFET source and drain got swapped. The symbol is upside down on the schematic, so it matches the fan drivers but drain and source are opposite in the symbol. Had some boards built at #58484556917e8c7f926e563aec05edcaa463c25e and the heater is always active.

Working on a PR to fix it up but wanted to post an issue since it affects the heater. I'm not very fluent with Kicad, so it might take me a little while.

Is it possible to buy?

Capturing this discussion from #3:

As a side note, the power handling increase going from the AO3400A to AON7400A is probably lost due to the SS54 diode on the power input being limited to 5A. Using another AON7400A could be suitable for reverse polarity protection instead of the diode. BOM cost increase would be fairly small since the extended part cost of the AON7400A is already done by using it once.

pls, add MAX31865, bltouch and runout connector(AH3364Q-P-B) support.

C487384 part #. 8x10 footprint. NEW

C59944 part #. 10x10 footprint. Old

both fit but c59944 is very tight

Is there no klipper config to set usb only?

USB doesn't work with this
