Описание
The wi-fi module and Bluetooth, based on the system ESP32. On board is 8 GPIO ports with support for I2C and SPI, analog input and a connector with a 3.7 V lipol battery. It has a software in the Arduino IDE.
The product is compatible with Arduino
In the Adafruit website, you can findthe user manual along with support forthe Arduino IDE.
Module dimensions: 51 x 22.7 x 7.3 mm, terminal pitch is 2.54 mm. The kit includes: module and goldpinstrips for self-soldering.
Mobile projectsController Feather designed for mobile projects. Thanks to the integrated connector, possible is powering it from the rechargeable battery LiPol 3.7 V. The battery voltage was led through an analog pin so you can constantly monitor the state of charge of lipol. Also, available is powering from the microUSB port.
Leads
Pin Description BAT Voltage with a lipol battery 3.7 V. EN Pin disabling voltage regulator 3.3 V after you attach the low state. By default, in the high state. USB The voltage of the microUSB port is 5 V. RST
Pin to reset the system after indicating the low state. By default, in the high state. It has a voltage converter 3.3 V - 5 V
3B Regulator's output 3.3 V. NC Not connected. GND The weight of the system.A0, A1, A2,
A3, A4, A5
Analog inputs or GPIO SCLClock pin of I2C communication.
SDAData pin of I2C communication.
SCK Clock pin of SPI communication. MISOPin of input data of the SPI communication.
