Jarrett's uMesh ESP32 module is battery ready, has circuit protection, power supply, and antenna, all in a tiny 1-inch package. S-8254AA: lithium battery protector, provides protections for over-charge, over-discharge, over-current, and short circuit. He recently completed a project with an ESP32 Pico D4 and an OLED display that fits exactly on an AA battery holder, which he populated with a rechargeable 14550. This board also includes 18650 battery charging system and two LEDs to indicate the battery state. Weighing in at 50 grams with battery and SD card, its not the lightest option but its a nice action camera to boot.
