Description
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 module has soldered connectors.
|
The product is compatible with Arduino On the Adafruit website, you can find the user manual, along with support for the Arduino IDE. |
Module dimensions: 51 x 22.7 x 7.3 mm, terminal pitch is 2.54 mm, it has soldered connectors.
Mobile projects
Controller 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. |
