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...
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 ...
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 board to come on when you plug usb in ? if you want it on, you can...
The main reason we are using ESP32 as the client and not another Nano 33 BLE is because it is more powerful and it can connect to several peripherals simultaneously, and you might need it incase you need to send the data from the Nano to the Cloud The communication between BLE devices i...
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 ?
DS3231 is an RTC sensor that can be used for timekeeping. It has a battery backup that can keep time accurate even if your microcontroller board is turned off. To interface ESP2 with DS3231, you must install the RTClib library in your Arduino IDE. After that, you have to connect the ...
For my situation this limitation would be somehow acceptable, because both my battery racks are feeding the same bus bar (the same off-grid solar system). So I could always work with the broadcast address (0x108080FE) to control them in parallel (on/off, voltage and current limit settings...

How deep sleep is used in ESP32 As mentioned, ESP32 is a power-hungry chip. So, its deep sleep mode is particularly useful in battery-powered networking applications. It lets the chip mostly remain in deep sleep or idle state, waking periodically to execute assigned tasks. These tasks...
