An all-in-one development board with a display interface that runs on the excellent ESP32-S2 WiFi module.
This feather is ideal for usage with CircuitPython or Arduino with inexpensive WiFi because it has native USB and 4 MB of flash plus 2 MB of PSRAM. It can function as a disk drive or a keyboard because it is native to USB. For IoT projects, WiFi indicates that 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's cutting-edge power and RF performance make it a great option for a wide range of applications.
-
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
-
Color 1.14" IPS TFT with 240x135 pixels - bright and colorful display with ST7789 chipset that can be viewed at any angle.
-
Three User Tactile buttons - D0, D1, and D2. D0/BOOT0 is also used for entering ROM bootloader mode if necessary.
-
Power options - USB type C or Lipoly battery
-
Built-in battery charging when powered over USB-C
-
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 40~50uA of current draw from the Lipoly connection. Quiescent current is from the power regulator, ESP32-S2 chip, and Lipoly monitor. Turn off the NeoPixel and external I2C/TFT power for the lowest quiescent current draw.
