Thanks!
Yeah why not, I can create an article here and I can do one in Italian as well. I’m Italian by the way 😀
How to create an article? When I’ve a bit of time I will do it
Thanks for the suggestion! Very appreciated!
I’m actually already using a specific circuit for recharging that use a solar panel, so it will be just useful to use the step up. I didn’t think about that!
By the way, this is my first version of the project, but I’m going to expand it with even more feature, and the radio module is one of them, together with a multiplexer for many I2C devices with same address
Hi Renzo,
Yeah I know, in fact I was unfortunately doubt about the 3.7V from the battery as well. The problem is that I want to find a reliable source of 5V for outdoor use. What about something like 3 AA battery in series 4.5V
I’ve a solar circuit designed for my board that charge the lithium battery, but I don’t have anything to recharge the Alkaline battery 1.5V. In that case I may need to change them often, even the module doesn’t consume much power when sleeping, when active I think it use something like 100mA. I’m not sure how long it will last with a battery pack
Thanks for the reply! I was looking also on the other library regarding the E22 module that is very interesting. I think the pin configuration should be the same. Am I right?
For the AUX pin I can use pin 15 as the shield with a pull up resistor, but for M1 and M0 I can use pin 27 and pin 25 if I read correctly, they should be fine.
In final production phase I will probably just connect M0 and M1 directly to 3.3V or GND depending on the use. I was wondering: I know that the module works better with higher voltage than 3.3V, I’m powering up everything with an 18650 battery, can I power also the E22 module with the battery in order to have higher voltage than 3.3V, instead of power the E22 with the 3.3V from the ESP?
