- Tue Aug 30, 2022 10:07 am #95173 I have a project which has been running on a NodeMCU with Arduino software.
This has been running fine with the original module type.
I recently bought some modules from BangGood, also as NodeMCU - but narrower.

The newer module would not load. Working from other sources, a large cap from EN to gnd fixed that problem.
Now my program compiles and loads, but doesn't run!
Nothing from the program (which asks for a valid network), and the WDT times out.
I've also tried programming the module only - with no external connections. Same same!

Any ideas??

- Wed Aug 31, 2022 11:36 am #95184 In Boards Manager I have used "NodeMCU 1.0 (ESP-12 Module) for each.
This worked originally, and seemed to be descriptive of the new module.
Amy suggestions on what I should try changing it to?

- Wed Aug 31, 2022 7:58 pm #95187 Without knowing what your new board is I have no idea - the key thing I would be checking is the memory on the board. Make sure you know the size and whether it's QIO or DIO. They are the things that make the boards different
