Wemos D1 V1.0.0-ESP32 CP2104 Development Board WiFi and Bluetooth Module D1 LOLIN32 ESP32 Dual Core CPU 4MB Flash

Description

Product Overview

The Wemos D1 V1.0.0 ESP32 Development Board (also known as the LOLIN32) is a powerful, feature-packed IoT development board that combines the immense capabilities of the ESP32 dual-core processor with the convenience of a compact, breadboard-friendly form factor. This board is an ideal upgrade path from ESP8266-based boards, offering built-in WiFi and Bluetooth (BLE) connectivity, significantly more processing power, and a lithium battery charging circuit for portable applications.

Unlike standard NodeMCU ESP32 boards that lack native battery support, the Wemos D1 ESP32 features an onboard LiPo battery connector and charging circuit. This allows your projects to run on a single 3.7V lithium battery, which can be recharged directly via the USB port, with a maximum charging current of 500mA. The board’s ultra-low power consumption (deep sleep current as low as 0.015mA) makes it perfect for battery-powered IoT sensors, wearable devices, and remote monitoring systems.

The board is equipped with the ESP-WROOM-32 module, which houses a Tensilica Xtensa 32-bit LX6 dual-core processor running at up to 240 MHz, with 4MB of flash memory and 520KB of SRAM. It uses the reliable CP2104 USB-to-serial chip, ensuring stable communication and easy programming via the Arduino IDE. All 26 digital I/O pins and 12 analog inputs are clearly labeled and broken out, making it simple to connect sensors, actuators, and displays.

Key Features

• ESP-WROOM-32 Module: Powered by the Espressif ESP32 dual-core processor with integrated WiFi 802.11 b/g/n and Bluetooth 4.2 (BLE) for versatile wireless applications.

• LiPo Battery Support: Onboard PH2.0 battery connector and charging circuit allow the board to run on a single-cell lithium battery and be recharged via USB (max charging current 500mA).

• CP2104 USB-to-Serial Chip: High-quality USB interface chip ensures reliable communication, stable driver support, and easy programming across Windows, macOS, and Linux.

• 4MB Flash Memory: Ample storage for complex IoT applications, OTA (Over-The-Air) firmware updates, and data logging.

• 26 Digital I/O Pins: Includes support for UART, I2C, SPI, DAC, capacitive touch sensors, and PWM outputs—breaks out most of the ESP32’s peripheral functions.

• 12 Analog Inputs (12-bit ADC): Integrated high-resolution analog-to-digital converter for reading sensors like potentiometers, temperature sensors, and joysticks.

• Compact & Breadboard-Compatible: Measures approximately 58mm x 25.4mm (similar to D1 mini but slightly longer), fitting neatly on a breadboard with ample space for connections.

• User LED & Reset Button: Onboard programmable LED (GPIO2) for status indication and a central reset button for easy debugging.
