For EC200UEU module, after applying VBat does PWRKEY need to be pulled low for
VDD_EXT to become 1.8V?

Hi @PhilipSimons
When the module is in shutdown mode, you can power on the module by holding down the PWRKEY for at least 2 seconds. An open set drive circuit is recommended to control the PWRKEY pin.
