Hello, I am working on a IoT project that involves using the wifi and ble capabilities of the esp32-c3-mini-1. The problem is that I am very space constrained (as even a 20mm coin cell battery does not fit inside the device that I am trying to incorporate this chip in). Is there any battery solutions that could work given the scope of my project? (The battery needs at least should have a good current capacity for at least a year and a half of operation in deep sleep as well as have a high discharge rate to support the RF requirements. The transmitting current consumption is in the 300mA and receiving us 82 - 84mA).
Or is there a way to use the coin cell batteries that I have (SR936) and attach them in such a way (2 in series and 1 in parallel with the other 2) to reach a nominal 3.1V and a 150mA current capacity. The problem with this, however, is that the discharge rate is really low at 100uA. Is there any component out there that can step up the output current for the esp32-c3-mini-1 or are coin cell batteries just not a viable option. (I liked coin cells since they fit in the size constraints).
If there is no such battery or battery configuration with the SR936, are there any recommendations on how I can achieve the goals of this project (to use wifi and ble for communication via app). That is, is there a better mcu to use?
