BASE26 compatibility with Core2?
-
I purchased a base26 for use with my Core2 however when powered by the DC barrel jack the core2 flashes the backlight and does not power up. I have two of these base226 units and neither appears to function with the Core2. I found no mention in the specification that indicates compatibility with Core2 or not. Should it work? Is there an alternate for Core2?

Hello @_Rob
yes, judging from looking at the schematic I think it should be compatible.
You'll need to adapt the program slightly to allow M5Core2 being powered from the DC jack. Try changing the last parameter of
M5.begin()fromkMBusModeOutputtokMBusModeInput.Explanation: in M5Core2 the 5 V pin on M-Bus needs to be actively switched between input or output as required. At startup the 5 V pin is set as an input allowing the M5Core2 to power up, but as soon as the
M5.begin()function is executed, by default the 5 V pin is being changed to become an output and thus power is cut again. With the aforementionedkMBusModeInputthis can be prevented and the 5 V pin continues to be an input.Thanks

@_rob I have the same concerns, the tracks of the BASE26 module touch the vibrator motor (in red on photo). This causes the CORE2 to restart constantly.
I notified M5Stack support to warn of the incompatibility

The vibration sensor of M5Core2 and M5 Base series are incompatible in mechanical design. Please do not stack them together.
