VDD_SDIO is not pulled low when entering deepsleep. So flash and psram aber active in deepsleep. Any ideas how I could change that?

Hi jimmo, thanks for your help! This is the code I use, maybe I can switch something of in the Code? import time import machine led = machine.Pin(21, machine.Pin.OUT) while True: # 30 Secs blink for i in range (0, 15): time.sleep(1) led.value(1) time.sleep(1) led.value(0) # 30 secs deepsleep machine...

Hello Forum, I‘ve got a TTGO T8 v1.7 Board, details can be found on Github https://github.com/LilyGO/TTGO-T8-ESP32 and I‘ve attached the schematics. The board can be powered by a Battery and this battery does only provide the 3.3V rail. Seems pretty right to me! But when I use machine.deepsleep() an...

You want to look up the specs of the microcontroller itself: https://www.st.com/en/microcontrollers- ... 2f7x2.html

@RajaRamesh:
You simply switch on or off the Pin which is connected to the Relay. There is no magic involved here!

By the way: You can think of voltage as the force with which a water stream flows (water high up from a mountain has more force). The current is the amount of water flowing.

So you stream from the ESP8266 has enough force but simply it is not wide enough and so it‘s not enough water.

The relay module should be controllable by an ESP8266 board. You power it via 5V from the esp board and use a 3.3V gpio pin to trigger it. It‘s not actually really specified to get switched by 3.3V instead of 5V but it should work. The think you struggle with right now is not voltage, it‘s current. ...

See the shematic: As far as I know there is no debouncing happening anywhere. You need to do it yourself.

You need to use an relay: https://www.instructables.com/id/WiFi-I ... 8266-Quic/

Do you have a link to the board?

Flash is typically 512 KB to 4 MB. But don‘t worry, even 512 KB are enough for starting.
