OUTLINE M5Stick CORES3 is ESP32 board which based on ESP32-S3 chip, contained 2-inch TFT screen. The board is made of PC+ABC. 1.1 Hardware Composition The hardware of CORES3: ESP32-S3 chip, TFT screen, Green LED, Button, GROVE interface, TypeC-to-USB interface, Power Management chip and battery. ESP32-S3 The ESP32 is a dual-core system with two Harvard Architecture Xtensa LX6 CPUs. All embedded memory,external memory and peripherals are located on the data bus and/or the instruction bus of these CPUs.With some minor exceptions (see below), the address mapping of two CPUs is symmetric, meaning that they usethe same addresses to access the same memory. Multiple peripherals in the system can access embeddedmemory via DMA. TFT Screen is a 2-inch color screen driven ILI9342C with a resolution of 320 x 240. Operating voltage range is 2.6~3.3V, working temperature range is -25~55°C. Power Management chip is X-Powers's AXP2101. The operating voltage range is 2.9V~6.3V and the charging current is 1.4A. CORES3 equips ESP32 with everything needed for programming, everything needed for operation and development 4 2. PIN DESCRIPTION 2.1.
