The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit ESP32-S2 Reverse TFT Feather!

Like Missy Elliot, we like to “put our [Feather] down, flip it and reverse it” and that’s exactly what we’ve done with this new development board. It’s basically our ESP32-S2 TFT Feather but with the 240×135 color TFT display on the back-side not the front-side. That makes it great for panel-mounted projects, particularly since we’ve also got some space for 3 buttons to go along. It’s like an all-in-one display interface dev board, powered by the fantastic ESP32-S2 WIFI module.

This feather comes with native USB and 4 MB flash + 2 MB of PSRAM, so it is perfect for use with CircuitPython or Arduino with low-cost WiFi. Native USB means it can act like a keyboard or a disk drive. WiFi means it’s awesome for IoT projects. And Feather means it works with the large community of Feather Wings for expandability.

The ESP32-S2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.

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
• Color 1.14″ IPS TFT with 240×135 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.
• Works with Arduino or CircuitPython
