Adafruit announced the launch of a new product this week. 240×135 color TFT display Placed on the back of the Feather board instead of the front. The Adafruit ESP32-S2 Reverse TFT Feather measures 52 x 23 x 9.7 mm and is available now for $24.95, perfect for panel mount projects. The 3-button Feather comes with native USB and 4MB Flash + 2MB PSRAM, making it perfect for use with CircuitPython or Arduino with low-cost WiFi.
The ESP32-S2 is a highly integrated, low-power 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that not only incorporates native USB, but also some interesting new technologies such as Time of Flight distance measurement. or installed. With state-of-the-art power and RF performance, this SoC is an ideal choice for various application scenarios related to Internet of Things (IoT), wearable electronics and smart home. ”
Note that the Feather ESP32-S2 has a single-core 240 MHz chip, so it’s not as fast as the dual-core ESP32. Also, there is no Bluetooth support. However, we are very excited to unlock a lot of features for advanced interfacing with the ESP32-S2’s native USB! It comes with flash and 2MB of PSRAM so you can buffer huge JSON files for parsing!”

– Power Options – USB Type C or Lipoly Battery
– Internal battery charging when powered via USB-C
– LiPoly Battery Monitor – LC709203 chip actively monitors battery for voltage and state/percentage of charge reporting via I2C
– Reset and DFU (BOOT0) button to enter the ROM bootloader (this is a USB serial port, so no separate cable needed!)
– Serial debug output pin (optional, for checking hardware serial debug console)
– STEMMA QT connector for I2C devices, with switchable power supply to enter low power mode.
