I would like to use the ESP32S UNO PSRAM with a 3.7 Lithium battery. Can you recommend a battery that I can purchase? I ordered one but the plug is the incorrect size. I chose not to solder the battery leads to the provided plug in case there might be other issues.
I purchased these batteries from Amazon: MakerFocus 4pcs 3.7V Lithium Rechargable Battery JST1.25 Connector 2pin, 852540 3.7V 1000mAh Battery with Protection Board and Insulated Rubber Tape Compatible with ESP32 Development Board WiFi Kit
Yes, you will be needing a 2mm pitch instead of 1.25. That jst1.25 standard probably aims to be as compact as possible for those mini ESP32 boards.
The Arducam ESP32S UNO, on the other side, takes the form factor of an Arduino UNO, so we can pretty much say that it speaks more Arduino when it comes to the hardware accesories.
