ESP32@10MHz uses 8mA

Big ESP32 + SX127x topic part 3

ESP32 power consumption at different CPU speeds I conducted some basic power consumption tests with an ESP-WROOM-32 module on a bare breakout board, and a simple test script using the Arduino framework. Script: Switch a GPIO port between high and low state with a 5s interval (delay(5000)) and write state information to the serial port. Tested with CPU frequencies 240MHz, 160MHz, 80MHz, 40MHz and 10MHz. The tests ran fine with correct timing. (As expected but I had not tested this with lower …
