ESP32-S3-N16R8 WiFi Bluetooth IoT Development Board ESP32-S3-N16R8 WiFi Bluetooth IoT Development Board
ESP32 S3 Dev Board - 16MB Flash, 8MB PSRAM, 2 x USB-C
The ESP32-S3 development board is assembled with an original ESP32-S3-WROOM-1 module from Espressif, with 16MB Flash and 8MB PSRAM (ESP32-S3-WROOM-1-N16R8). It is a general-purpose Wi-Fi + Bluetooth LE MCU module that integrates complete Wi-Fi and Bluetooth LE functions. Most of the I O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing.
The ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b g n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. ESP32-S3 supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache. There is a RGB WS2812 LED connected to IO38. It has a Red, Green and Blue LED that are individually addressable. This module has 2 USB Type C connectors. The one is used to power the board, for flashing applications to the chip, as well as for communication with the chip via the on-board USB-to-UART bridge. It is connected to a UART of the ESP32 chip via a CH340 chip. The second USB connector is connected to the ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 specification. It can also be used to power to the board, for flashing applications to the chip, for communication with the chip using USB 1.1 protocols, as well as for JTAG debugging.

Descrie si implementari avansate:
- faciliteaza conexiune wireless a doua dispozitive ce au porturi fizice de RS 485, CAN si UART
- viteza stardard incepand de la 50 bps pana la 921600 bps
- latenta redusa tipic 5-10ms (max 20-25ms) pentru aplicatii critice unde acest indicator conteaza
- sincronizare tipic 1 secunda, resincronizare conexiune la min 5 sec incepe cautare - timp de timeout configurabil
- selectie canale de lucru 2.4Ghz de exemplu de la 2-6 ori fixe, etc
- cautare automata canale 1-13 si selectie cel mai liber Wifi 2.4Ghz
- reincepere cautare canale libere daca exista pierderi de pachete, semnal slab ori interferente radio (2 min timeout)
- reglaj automat al puterii in functie de semnal (comunica intre ele si ajusteaza semnalul automat individual)
- auto recovery daca bridge-ul s-a intrerupt
- meniu configrare parametri (baudrate, mac, semnal, canale selectie, timeout si parola)
- watchdog in diverse stagii in functii de lucru
- parola la meniu configuratie
- indicator stare led (searching, connected si link transmisii date)
- keep alive - PING (automat la 2 sec cand nu comunica si la max 60 sec cand exista comunicatie)
- wifi payload curat de informatii seriale max 250 bytes (e destul)
Meniu configuratie:
- adresa MAC (master slave)
- baud rate de la 50bps pana la 921600 bps
- setare timeout - tipic 5 sec (timpul minim in care decide cand e offline pentru a reincepe resincronizarea)
- setare min canal de lucru (1-13)
- setare numar max canal de lucru (1-13)
- setare semnal min acceptat (daca se seteaza max, el se va stabiliza la max marind automat puterea)
- setare parola meniu
De ce bridge over Wifi:
- la nivel hardware modulul driverul (485, CAN si UART) este izolat galvanic pe alimentare si comunicatie
- eliminarea de cabluri conexiune fara distrugere elemente de constructie
- conexiune intre dispozitive la distanta wireless, distanta depinde strict de castig antene cat si de mediu: exemplu antena 2-3 dbi in interior 10-30m si in exterior linie dreapta pana la 100m - fara obstacole
- viteza mare de transmisie (pana la 921600 bps)
- izolare galvanica (nu necesita conexiune fizica)
- un bridge universal configurabil in, aproape, orice interfatare cu orice dispozitiv
Nota:
- In principiu cu puterea de emisie standard (aproximativ de max 100mW) si cu antene unidirectionale cu castig 6-9dbi se poate ajunge cu usurinta la distane de pana la 1000m (in linie dreapta).
