Das ESPDUINO-32 Board basiert auf dem ESP32 WROOM 32 Modul von Espressif.

Das ESPDUINO-32 Entwicklerboard vereint die typische Arduino Bauform mit dem ESP32.
Der ESP32 WROOM32 basiert auf der Xtensa Dual Core 32bit MCU in Kombination mit einem 4MB SPI Flash Speicher.

ESPDUINO ESP32 WROOM32 Entwicklerboard

Im Vergleich zu typischen ESP32 Entwicklerboards verfügt das ESPDUINO-32 Entwicklerboard neben einer USB Buchse zusätzlich über einen 5,5×2,1mm Hohlsteckeranschluss. Über den Hohlstecker anschluss kann das ESPDUINO-32 mit Eingangsspanungen von 5-12V versorgt werden.

Des Weiteren verfügt das ESPDUINOEntwickler Board über einen CH340 USB TTL Konverter, sodass eine direkte, serielle Kommunikation über die USB Schnittstelle erfolgen kann.

Der ESP32 WROOM32 unterstützt

• 802.11 b/g/n Standard
• HT40 WLan Transceiver
• Bluetooth bis 4.2
• Takfrequenz 160MHz
• SRAM 512kBytes
• 4MB 32Mbit SPI Flash

ESPDUINO ESP32 WROOM32 Development Board

Compared to typical ESP32 development boards, the ESPDUINO-32 development board has besides a USB socket also a 5.5×2.1mm barrel connector. The ESPDUINO-32 can be supplied with input voltages of 5-12V via the barrel connector. Furthermore, the ESPDUINO developer board has a CH340 USB TTL converter on board and support a direct, serial communication thru USB interface.
