 **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!
- **WROVER module** has FCC/CE certification and comes with 4 MByte of Flash and 2 MByte of PSRAM - you can have huge data buffers
- **Lotsa power options** - 6-12VDC barrel jack **or** USB type C **or** Lipoly battery
- **Built-in battery charging** when powered over DC or USB
- UNO-shape so shields can plug in
- **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 pins** (optional, for checking the hardware serial debug console)
- **JTAG pads** for advanced debugging access.
- **On/Off switch**
- **STEMMA QT** connector for I2C devices
- **On/Charge/User** LEDs + status **NeoPixel**
- **Works with Arduino or CircuitPython**
- **53.2mm x 72mm / 2" x 2.8"**
- **Height (w/ barrel jack): 14.8mm / 0.6"**
- **Weight: 22.5g**
