My not final schematic:
The things I want to achive:
- LiPo battery operation (JST-PH2)
- UART Programmibility
- A few sensor on the I2C bus
- Optional deep sleep
- 8 exposed pins for testing
The topics that are bit unclear and I would be grateful to get some insight are:
- How exactly the deep sleep and the wakeup works?
- Is this board sufficient to be programmed with an USB->UART programmer?
- Are there any hidden differences between the ESP8566 and the ESP8585 (besides the larger memory)?
