Add configurable startup delay before power latch activation - #600
Merged
Conversation
Add STARTUP_DELAY_MS (default 1000 ms) to prevent the board from latching on when the MCU is briefly back-powered through unexpected means such as UART. The delay is applied after peripheral init but before the self-latch GPIO is set, so a transient power source will lose power during the window and never engage the latch.

Instead of a delay, it is better to monitor the battery voltage. |
