It can lithium battery powered, the lithium battery is not included, battery may be purchased here: https://www.amazon.com/dp/B07CXNQ3ZR; ★Add battery power detection circuit. Use ADC2_4 (GPIO 13) to read battery voltage. Please refer to this example: https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/examples/ESP32/ADC_Read_Voltage/Battery_power/Battery_power.ino [This is an upgraded version WiFi Kit 32! ] What's the Upgrade of New WiFi Kit 32? 1. 4MB (32M-bits) FLASH upgrade to 8MB (64M-bits) FLASH; 2. Better 2.4GHz antenna design and impendence matching; 3. Basic low power design (800uA in deep sleep); 4. Add battery power detection circuit. Use ADC2_4 (GPIO 13) to read battery voltage. Please refer to this example: ★https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/examples/ESP32/ADC_Read_Voltage/Battery_power/Battery_power.ino; 5. Add Vext power output pin, users can use this pin to drive some external device (sensor, motor etc.), when system need into deep sleep mode, Vext can be turn off. This pin was controlled by GPIO21, for example: Turn ON: digitalWrite(21, LOW); Turn OFF: digitalWrite(21, HIGH); 6.
