6 days agoYou have connected 1k resistor to program pin of TP4056 to ground. That means that you want to charge your battery with 1A of current! Isn't that abit too excessive? I would lower that charging current by half so that IC chip doesn't blow for being too hot!
But the main reason why your ESP is not working is that you are missing a FLASH chip. Only ESP32-C6FH4 or ESP32-C6FH8 contains internal Flash memory. Basic C6 model hasn't got an internal flash memory.
Other issues:
-Your antenna doesn't have compensating PI filter.
-You don't have a battery BMS circuit, so you need to heavily rely that LI-Po or Li-ion battery that you have bought has a built-in BMS
-Your 3.3V regulator has a small drop-out voltage. So if your battery is nearing 3.3V then your regulator output is no longer able to maintain 3.3V output because of that drop-out voltage. This is when you get into trouble and brownout situations....
-Pins 5, 28, 37 and 40 from the ESP32 should be fed through a filter that filters 3.3V. So, L1 is filtering the incorrect pins.
-Your schematic doesn't fully mirror the PCB layout, Like 3.3V is on the schematic:VDD33 and in PCB layout it is: VDDA
-There might be parasitic capacitance on the RF trace because how it is now routed. If you don't get enough transmission power, then this might be the propable cause.
