A dev board with the form factor of a XIAO ESP32S3, but without the need to depress the Bootloader and Reset buttons every time you want to upload a new sketch. One may argue that depressing those buttons is no big deal, but consider that an IoT project could very well entail the MCU/circuit board b...

The code suggested by liaifat85 does not work as intended. The ESP32 enters deep sleep and awakes per the defined time intervals, but it appears the code contained in the loop never gets executed. Therefore, I don't see any volts or amps values displayed either on the serial monitor or on my phone a...

Thank you @liaifat85...I appreciate your help!

I created an app that monitors my car battery's voltage, plus current from a trickle charger, via a Bluetooth LE connection to a XIAO ESP32S3 and power sensor. I plan to check the readings every 24 hours for about a minute or so. Ideally, the ESP32 would be in deep sleep mode for 23 hours and 59 min...

I've created an phone app that connects to a Bluetooth LE ESP32-S3 and power sensor. I'm using it to remotely monitor the voltage of my car battery via BLE. The ESP32-S3 and sensor are powered by the 12V car battery via an IC voltage regulator. I'd like to minimize the parasitic drain on the battery...

Thank you Mike...I appreciate your help.

I'm using an ESP32S3 with an Adafruit INA260 voltage/current sensor. I'm powering the ESP32 with 5V from an L7805CV linear voltage regulator (including the necessary filtering capacitors). The INA260 can be powered with either 5V or 3.3V. Would it be preferrable to power the INA260 with the 3.3V out...
