This is the newly released Adafruit ESP32-S2 Feather, which has an integrated BME280 temperature, humidity, and pressure sensor! Featuring native USB and 4 MB of flash plus 2 MB of PSRAM, this board is ideal for use with inexpensive WiFi-enabled CircuitPython or Arduino. It can function as a disk drive or a keyboard because it is native to USB. For IoT applications, WiFi means it's fantastic. Additionally, Feather denotes that it integrates with the huge Feather Wings community for expandability.
The ESP32-S2 is a 2.4 GHz Wi-Fi System-on-Chip (SoC) that is highly integrated, low power, and now has native USB in addition to a few other intriguing new features including Time of Flight distance measurements. This SoC is a great option for a range of application scenarios because to its cutting-edge power and RF performance.
Features
-
ESP32-S2 240MHz Tensilica processor - the next generation of ESP32, now with native USB so it can act like a keyboard/mouse, MIDI device, disk drive, etc!
-
Mini module has FCC/CE certification and comes with 4 MByte of Flash and 2 MByte of PSRAM - you can have huge data buffers
-
Power options - USB type C or Lipoly battery
-
Built-in battery charging when powered over USB-C
-
BME280 temperature / humidity / barometric pressures sensor connected over I2C on address 0x77 for immediate ambient weather sensing.
-
LiPoly battery monitor - MAX17048 chip actively monitors your battery for voltage and state of charge / percentage reporting over I2C
-
Reset and DFU (BOOT0) buttons to get into the ROM bootloader (which is a USB serial port so you don't need a separate cable!)
-
Serial debug output pin (optional, for checking the hardware serial debug console)
-
STEMMA QT connector for I2C devices, with switchable power, so you can go into low power mode.
-
On/Charge/User LEDs + status NeoPixel with pin-controlled power for low power usage
-
Low Power friendly! In deep sleep mode we can get down to 80~100uA of current draw from the Lipoly connection. Quiescent current is from the power regulator, ESP32-S2 chip, and Lipoly monitor. NeoPixel and I2C are powered from a separate LDO regulator and can be disabled to get lowest quiescent current possible.
-
Works with Arduino or CircuitPython
