Now V2 is almost done, some small DRC errors to fix before I can order it.

Functions in V2:

• Charger can be disable if using non LiPo batteries.
• Powersupply has two diodes to prevent battery from being connected to USB/CP2104 and USB from directly connecting to battery.
• CP2104 is supplied from USB so it should not draw power from battery
• Auto Reset when programming in same way as nodeMCU
• ADC to battery with ~2 ms on time of the voltage divider to save power
