1.1 Konpozisyon pyès ki nan konpitè
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 use the same addresses to access the same memory. Multiple peripherals in the system can access embeddedmemory via DMA.
TFT Screen se yon ekran koulè 2-pous kondwi ILI9342C ak yon rezolisyon 320 x 240.
Opere voltage ranje se 2.6 ~ 3.3V, ranje tanperati k ap travay se -25 ~ 55 ° C.
Chip Jesyon pouvwa se AXP2101 X-Powers. Operasyon voltage ranje se 2.9V ~ 6.3V ak aktyèl la chaje se 1.4A.
StackChan equips ESP32 with everything needed for programming, everything needed for operation and development

DESKRIPSYON FONKSYONÈL
Chapit sa a dekri plizyè modil ak fonksyon ESP32-S3 yo.
3.1.CPU AK MEMWA
Xtensa® doub-nwayo 32-bit LX7 mikro, jiska 240 MHz
- 384KB ROM
- 512 KB SRAM
- 16 KB SRAM nan RTC
- SPI, Doub SPI, Quad SPI, Octal SPI, QPI ak OPI entèfas ki pèmèt koneksyon ak plizyè flash ak RAM ekstèn
- Kontwolè Flash ak kachèt sipòte
- Flash in-Circuit Programming (ICP) sipòte
3.2.DESKRIPSYON DEPO
3.2.1. Ekstèn Flash ak SRAM
ESP32-S3 sipòte SPI, Dual SPI, Quad SPI, Octal SPI, QPI ak OPI interfaces ki pèmèt koneksyon ak plizyè flash ekstèn ak RAM.
The external flash and RAM can be mapped into the CPU instruction memory space and read-only data memory space. The external RAM can also be mapped into the
CPU data memory space. ESP32-S3 supports up to 1GB of external flash and RAM, and hardware encryption/decryption based on XTS-AES to protect users’programs and data in flash and external RAM.
Atravè kachèt gwo vitès, ESP32-S3 ka sipòte nan yon moman jiska:
- External flash or RAMmapped into 32 MB instruction space as individual blocks of 64 KB
- Ekstèn RAM trase nan espas done 32 MB kòm blòk endividyèl 64 KB. 8-bit, 16-bit, 32-bit, ak 128-bit lekti ak ekri yo sipòte. Flash ekstèn kapab tou trase nan espas done 32 MB kòm blòk endividyèl 64 KB, men sèlman sipòte lekti 8-bit, 16-bit, 32-bit ak 128-bit.
3.3.CPU CLOCK
Revèy CPU a gen twa sous posib:
- Ekstèn prensipal revèy kristal
- Entèn vit RC osilator (tipikman sou 17.5 MHz, ak reglabl)
- PLL revèy
Aplikasyon an ka chwazi sous la revèy nan twa revèy ki anwo yo.
The selected clock source drives the
CPU clock directly, or after division, depending on the application. Once the CPU is reset, the default clock source would be the external main crystal clock divided by 2.
3.4.RTC AND LOWPOWER MANAGEMENT
Avèk itilizasyon teknoloji avanse jesyon pouvwa, ESP32-S3 ka chanje ant diferan mòd pouvwa. (gade tablo 1).
- Mòd aktif: CPU ak radyo chip yo mache sou. Chip la ka resevwa, transmèt, oswa koute.
- Modemsleep mòd: CPU a fonksyone epi vitès revèy la ka redwi. Baseband san fil ak radyo yo enfim, men koneksyon san fil ka rete aktif.
- Lightsleep mode: The CPU is paused. The RTC peripherals, as well as the ULP coprocessor can be woken up periodically by the timer.
Any wake-up events (MAC, host, RTC timer, or external interrupts) will wake up the chip. Wireless connection can remain active. Users can optionally decide what peripherals to shut down/keep on (refer to Figure 1), for power-saving purpose. - Mòd Deepsleep: CPU ak pifò periferik yo koupe.
Only the RTC memory is powered on and RTC peripherals are optional. Wi-Fi connection data are stored in the RTC memory. The
Koprosesè ULP fonksyonèl.
