Categroy

Description

Control

FireBeetle enable/reset pins

Touch

Pin with capacitive touch function

Analog

Analog pin

Port PIN

Default physical pin number of the chip, which can be used to directly control the corresponding pin

Arduino

IDE

In Arduino IDE, the pin numbers have been remapped by FireBeetle, and you can directly use this symbol to control the

corresponding pin

RTC PIN

FireBeetle 2 ESP32-E supports low power function, and in Deep-sleep mode, only RTC pin keeps working and can be used

as a wave-up source. When RTC pin is used as an output pin, it keeps outputting level value when the chip is in Deep-sleep

mode, while as an input pin, it can wake up the chip from Deep-sleep.

GND

Common ground for all power supplies and logics

Power

When powered by 5V-USB, VCC outputs about 4.7V and 3V3 outputs 3.3V; When powered by 4V li-ion battery, VCC

outputs about 4V and 3V3 outputs 3.3V(Actual measurement)

FireBeetle 2 ESP32-E has up to 24 physical GPIOs, which are mainly for connecting peripherals like sensors, actuators, etc. Meanwhile,

these IO pins can be multiplexed for other functions such as UART, SPI, I2C and so on. The table below provides users with a detailed

description of FireBeetle 2 ESP32-E GPIO.
