Description
WeMOS D1 R32 ESPDuino32 4MB Wi-Fi and Bluetooth Board is already integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters, and power management module. The entire solution takes up the least amount of printed circuit board area. This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low power technology, power and RF properties best, which is safe, reliable, and scalable to a variety of applications.
Wemos D1 R32 is ESP32 Based WiFi/Bluetooth Board in Arduino UNO form factor. The UNO form factor lets you use existing Arduino Shields with ESP32 Wireless CPU. All I/O pins are 3.3V
The ESP32 chip integrates a dual-core processor with 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, clocks & Times, abundant peripheral Interfaces and security mechanism.
Software can be developed using many different platforms, including Arduino. It is designed for Generic low power IoT sensor hub, loggers, video steaming for camera, Wi-Fi & Bluetooth enabled devices, Home automation and mesh network applications, aimed at makers, hardware engineers, software engineers and solution provides.
The ESP32 is the most integrated solution for Wi-Fi + Bluetooth applications in the industry with less than 10 external components. ESP32 integrates the antenna switch, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. As such, the entire solution occupies minimal Printed Circuit Board (PCB) area.
