I want to know the way to reduce power consumption more and ensure ESP-NOW communication.
I have questions about ESP-NOW utilization. Background : I want to make a system that several battery-powered sensor modules, i.e., master, from ESP32 , and a slave that receive data from all sensor modules of ESP32 , of which communication is by esp-now. The sensor modules should have batteries so...

Re: [ESP-WROOM-32]Mainly, How to communicate with I2C sensor requiring higher current than GPIO can flow.
Thank you for teaching politely! it is helpful for me. I could understand that 75 mA does not flow through I2C. I'm happy if you could answer additional questions. 1. I'm thinking of connecting the 3V3 pin of Esp32 to the power supply pin of the sensor, is it the same as what you intended? do I have...

[ESP-WROOM-32]Mainly, How to communicate with I2C sensor requiring higher current than GPIO can flow.
Hi. I am a beginner about embeded system. I use ESPr developper 32 development board of ESP-WROOM-32. The development framework is ESP - IDF (v3.1.2). I would like to connect this board to the SCD 30 (sensirion) sensor via I2C, and send sensor data to AWSIoT. Please ask you some questions about foll...
