ESP8266: Difference between revisions

Revision as of 05:38, 26 November 2022

A series of 32-bit microcontroller units from Espressif, followed by the ESP32. The first generation of the NodeMCU SoC was based around ESP8266.

There is only one (10-bit) ADC, and it reports values between [0, 1], not [0, 3.3]. This is not a scaling--the input voltage should not exceed 1V.
- This is not true for e.g. the NodeMCU, which applies a divider network to scale the 3.3V down to 1V. This allows supplying 3.3V to the external device.
- On the NodeMCU, this ADC can read the battery voltage instead of a connected external device. This is set in firmware.
