Adafruit has announced the impending release of another Feather-format development board, designed to combine an Espressif ESP32-S2 system-on-chip with a compact full-color TFT display: the ESP32-S2 TFT Feather.
"With a 4MB Flash/2MB PSRAM [Pseudo-Static RAM] ESP module on the bottom, and a 1.14″ 135×240 IPS TFT [In-Plane Switching Thin-Film Transistor display] on the top, its an adorable all-in-one," writes Adafruit's Phillip Torrone of the new design. "We revised this a few times to improve the low power capabilities but now its ready to ship."
The ESP32-S2 is an increasing popular microcontroller which entered mass production two years ago. Like others in the ESP32 family, it includes a 240MHz Xtensa LX7 central processing core — but it combines this with an ultra-low-power coprocessor built around the free and open source RISC-V instruction set architecture.
The system-on-chip also includes 320kB of static RAM (SRAM) and 128kB of flash ROM on-board, 802.11b/g/n 2.4GHz Wi-Fi with time-of-flight (TOF) calculation support, and a cryptographic subsystem with RSA secure boot and hardware acceleration of SHA, AES, and HMAC operations.
Adafruit's spin on a host for the SoC offers full pin compatibility with the Feather ecosystem, giving it plenty of accessories and add-ons to play with, while the on-board display makes visual feedback as easy as possible.
"We just have to finish testing the initial run," Torrone writes of the first batch of boards, and we’ll get these in stock soon." Pricing hasn't yet been confirmed, but more information is available in the Adafruit blog post.
