Why Choose WEMOS Lite V1.0?
- Compact form factor — smaller than standard ESP32 DevKit boards, ideal for space-constrained projects
- CH340G USB chip — reliable serial communication, widely supported on Windows/Mac/Linux
- MicroPython ready — flash MicroPython firmware and start coding in Python immediately
- Dual-core 240MHz — run WiFi stack on one core, application on the other
- 4MB flash — ample storage for MicroPython scripts, web server files, and OTA updates
- BLE + Classic BT — dual Bluetooth modes for both legacy and modern BLE devices
Typical Applications
- MicroPython IoT prototyping — rapid development with Python scripting on ESP32
- Compact WiFi + BLE sensor node — temperature, humidity, and environmental monitoring
- Home automation — MQTT client for Home Assistant, Node-RED, and OpenHAB
- MQTT data logger — publish sensor data to cloud platforms (AWS IoT, Adafruit IO)
- BLE beacon — proximity detection and asset tracking
- OTA firmware updates — update firmware wirelessly over WiFi
Compatible With
Compatible with Arduino IDE (ESP32 board package), MicroPython (ESP32 firmware), and ESP-IDF. Works with standard ESP32 libraries including WiFi, BLE, MQTT, HTTP, WebSocket, and I²C/SPI peripherals.
FAQ
Q: Does WEMOS Lite V1.0 support MicroPython?
A: Yes. Flash the official ESP32 MicroPython firmware via esptool.py and use Thonny or uPyCraft IDE to write Python scripts.
Q: Is CH340G driver required?
A: On Windows, install the CH340G driver. On macOS 10.9+ and Linux, the driver is usually included. Download from the official CH340 driver page if needed.
Q: What is the difference between WEMOS Lite and standard ESP32 DevKit?
A: WEMOS Lite is more compact with a smaller PCB footprint. It has the same ESP32 chip but fewer exposed GPIO pins compared to the full 38-pin DevKit.
