This week, Adafruit announced a new product launch 240 x 135 color TFT screen They are placed on the back side, not the front side of the badminton board. The Adafruit ESP32-S2 Reverse TFT Feather measures 52 x 23 x 9.7mm and is now available for purchase at a price of $24.95 and is ideal for breadboard projects. Featuring 3 buttons, Feather comes with native USB and 4MB Flash + 2MB of PSRAM making it ideal for use with CircuitPython or Arduino with low cost WiFi.
The ESP32-S2 is a highly integrated, low-power 2.4GHz Wi-Fi System-on-Chip (SoC) solution that now has built-in USB as well as some interesting new technologies such as trip distance measurements. . With its cutting-edge power and wireless performance, this SoC is an ideal choice for a variety of application scenarios related to the Internet of Things (IoT), wearable electronics, and smart homes.”
Please note that Feather ESP32-S2 has a 240MHz single-core chip, so it will not be as fast as an ESP32 with a dual-core. Also, there is no Bluetooth support. However, we are very excited about the ESP32-S2’s original USB unlocking so much potential for advanced interaction! This little ESP32-S2 module that we’re using on Feather comes with 4MB Flash and 2MB PSRAM so it can store huge JSON files for parsing! “
Adafruit ESP32-S2 Reverse TFT Feather Display Specifications
– Tensilica ESP32-S2240MHz Processor – Next generation ESP32, now with native USB so it can act as a keyboard/mouse, MIDI device, flash drive, etc!
– Small unit is FCC/CE certified and comes with 4MB of Flash and 2MB of PSRAM – you can have huge data stores
– 1.14″ IPS TFT color with a resolution of 240 x 135 pixels – Bright and colorful screen with ST7789 chipset that can be viewed from any angle.
– Three user tactile buttons – D0, D1 and D2. D0/BOOT0 is also used to enter bootloader ROM mode if needed.
– Power options – USB Type C or LiPoly battery
Built-in battery charging when powered via USB-C
– LiPoly Battery Monitor – The LC709203 chip actively monitors your battery for voltage and charge status / percentage reporting via I2C
– Reset and DFU (BOOT0) buttons to access the ROM bootloader (it’s a USB serial port so you don’t need a separate cable!)
– Serial debug output pin (optional, to check hardware serial debug module)
– STEMMA QT connector for I2C devices, with switchable power, so you can enter low power mode.
– On / Charge / User LEDs + status NeoPixel with pin controlled power for low power usage
Low energy friendly! In deep sleep mode, we can reach 40~50uA current draw from the Lipoly connection. The quiescent current comes from the power regulator, the ESP32-S2 chip, and the – lipolye display. Turn off NeoPixel and external I2C/TFT power for lower quiescent current draw.
