Adafruit has teased us with the announcement of the panel-mount TFT ESP32-S2 Wi-Fi Feather Board. It appears to be a succeeding version of the previous ESP32 Feather boards, by changing few positions of the components like the ESP32 module and USB-Serial converter, with the ESP32-S2-MINI module.
Apart from the NeoPixel in the schematic diagram, the STEMMA-QT header fits in the middle of the device. The four colorful dots indicate the vertical appearance of the connector. It serves the purpose of I2C as the larger JST PH connectors cannot fit on the compact feather board.
From the two Feather PCBs with ESP32-S2 SoC from the earlier devices, the panel-mount Wi-Fi Feather board has the TFT on the back and embedded with some tactile buttons. The TFT display makes the device quicker as it powers each pixel of the screen with a single MOSFET. TFT displays are mostly brighter than LCD displays.
From the Twitter handle of Adafruit Industries, it can be understood that the company has been working on all-in-one-device. Hence, including a TFT display and WiFi on a single feather board. The design process of the device had started at the time of the creation of PyPortals, which was around 2 years ago now.
The company says “It started designing a low cost ‘mini PyPortal’ that would be able to run CircuitPython similar to those lilygo all-in-one esp32+display boards, but it did not have circuitpython running directly on the original esp32”
