Using an external battery of 6V or 9V we can power ESP32 through the Vin pin by connecting the GND of ESP32 with the GND of the battery. Any voltage between 5V to 12V can be connected to an ESP32 Vin pin however it’s recommended to not use more than 9V external battery. As ESP3...
Last way on the list to power ESP32 is by using the external batteries. ESP32 runs on 3.3V so it can be easily powered using the external batteries. While powering ESP32 with an external battery, always use the Vin pin as it is connected to an onboard voltage regulator which protects ...
The ESP32 is intended to be suitable for low power applications - in other words, running on batteries. The optimal voltage for the ESP32 is 3.3V. The nominal voltage of a Li-ion battery is 3.7V but it can be anywhere between 3V and 4.2V. Many of the development kits come with the...
I have a few TTGO boards with a switch on them and the battery charge. It seems however that if you plug in USB , the esp32 comes in regardless of the switch position, so to charge the battery the esp32 has to be on. To me this seems pointless and a bad design, who wants the...
I'm using the example of ..\bluetooth\esp_hid_device to do some tests. I can use Lightblue APP on Android phone to read the battery level. It's 0x64 always. I can't find the code to change it. Could anyone can tell me after I get the voltage of battery how do I change the ...

Currently, I am using ESP32 PPPOS component for my device (ESP-32 BOARD) to connect with the internet via 4G SIM, and now I want this device to connect to another one via modbus tcp/ip but it did not work. What should I do ?
(for Wi-Fi control) and an FS1000A as RF transmitter. The project called433mhz_jam, isavailable on github.I also used a battery pack to power the device, so it's remote controlled and throwable. This allows for a better flexibility and to work real time on the attack instead of ...
