AI-Thinker ESP-32S Wifi Bluetooth Combo Module

Anmerkung: Falls Sie eine größere Menge für Ihre Produktion benötigen, wir haben diesen Artikel auch als ganze Rolle (800 Stück/Rolle)

Das ESP-32S Wifi Bluetooth Combo-Modul basiert auf dem ESPRESSIF ESP32 Chipsatz und bietet beste Performance bei geringem Stromverbrauch. Das ESP-32S verfügt über einen Dual-Core-Prozessor, 448 KByte ROM, 520 KByte SRAM, 16 KByte SRAM in RTC, 802.11 b / g / n / e / I Wi-Fi, Bluetooth v4.2 BR / EDR & BLE, Uhren & Zeiten, periphere Schnittstellen und einen Sicherheitsmechanismus.

Das Modul bietet SDK Firmware für die schnelle Online-Programmierung und Open-Source-Toolchains auf Basis von GCC für die Entwicklungsunterstützung. Das Modul wurde für Anwendungen als Low-Power-IoT Sensorhub, Logger, Video-Streaming für Kameras, Wi-Fi und Bluetooth fähige Geräte, Hausautomation und Mesh-Netzwerk entwickelt.

Der ESP32 ist ein 2,4-GHz-WLAN und Bluetooth Combo-Chip entwickelt mit der TSMC Ultra Low Power 40-nm-Technologie. Das ESP32 ist die meist verwendete WiFi + Bluetooth-Lösung in der Industrie und vereint den Antennenschalter, HF-Balun, Power-Verstärker, rauscharmen Verstärker, Filter und Power-Management, so dass es auf dem PCB wenig Platz einnimmt.
