ESP32-S3 based mostly 1.28-inch spherical touchscreen show helps Arduino programming

Makerfabs “ESP32-S3 Spherical SPI TFT with Contact 1.28″” is a small ESP32-S3 with a 1.28-inch spherical colour touchscreen show, a microSD card, help for USB and battery energy, and two “Mabee” extension connectors.

The board joins different ESP32-S3 spherical show boards such because the Lilygo T-RGB board or Seeed Studio’s Spherical Show for XIAO, however with a thinner design, and a sq. PCB with trimmed corners as a substitute of a spherical PCB like the opposite two.

ESP32-S3 Round Display 1.28-inch touchscreen

ESP32-S3 Spherical SPI TFT with Contact 1.28″ (E32S3128GC) specs:

  • Wi-fi MCU – Espressif Methods ESP32-S3R8 dual-core Tensilica LX7 microcontroller @ 240 MHz with vector extension, 512KB SRAM, 8MB PSRAM, Wi-Fi 4 & Bluetooth 5.0 dual-mode (Basic + BLE) connectivity
  • Flash – 128 Mbit (16MB) W25Q128JV SPI flash, microSD card slot
  • Show – 1.28-inch spherical LCD with 240×240 decision (GC9A01 SPI driver), touchscreen controller (CST816S)
  • USB – 1x USB Sort-C port
  • Enlargement
  • Misc – Reset and Flash buttons
  • Energy Provide
    • 5V (4.0V to five.25V) through USB Sort-C port
    • 2-pin jST connector for 3.7V Lipo battery
  • Dimensions – Round 32.5 x 36 mm
  • Temperature Vary – -40℃ to +85℃

The corporate offers {hardware} and software program documentation within the board’s wiki, in addition to a number of Arduino samples, as demonstrated within the video above, in GitHub, the place you’ll additionally discover PDF and EAGLE schematics. Arduino samples embrace code to attract a JPEG, undergo animated GIFs, an LVGL graphics demo/benchmark, a clock that appears like a mechanical watch, and a demo to attract textual content and numerous shapes on the show.

Makerfabs is promoting the “ESP32-S3 Spherical SPI TFT with Contact 1.28″” board (possibly they might have provide you with a shorter title) on their on-line store for $29.80 plus transport. Additionally they have a bunch of different ESP32 Sequence rectangular shows starting from 3.2-inch to 4.3-inch in measurement.The ESP32-S3 spherical show from Makerfabs is cheaper than the Lilygo mannequin (now round $37 together with transport), however the latter is barely bigger at 2.1-inch and provides a better 480×480 decision.
