Okay, to sum it up for Version 3.0.0 and 3.1.0:
|
|
|
|
|
|
|
|
|
|
1. UART is powered by 3.3V
|
|
|
|
|
2. Lift Pin16 (VCC) and Pin4 (V3)
|
|
|
|
|
3. Connect Pin16 to +V5 rail [or directly to VBUS, not tested yet]
|
|
|
|
|
4. Solder a capacitor between Pin1 (GND) and Pin4 (V3) 0.1µF
|
|
|
|
|
5. The M6211 has no reverse current protection! (use this instead RP108J or add a pMOSFET)
|
|
|
|
|
6. you get 3V on the +5V line while powering over 3.3V
|
|
|
|
|
7. I measured 76µA in deepsleep. (20µA ESP8266 Core, 40µA ME6211, 6µA CH340C ???)
|
|
|
|
|
8. completely stripped LDO leads to 17µA in deepsleep
|
|
|
|
|
9. Replace LDO with this MIC5219-3.3
