NodeMcu Lua WIFI Board Based on ESP8266 CP2102 Module
We have ✅ 12 available of the EC-DPO02102N in our Sydney warehouse. An extra 100 units available with a short lead time.
The NodeMCU R2 is a Wi-Fi development board based on the ESP8266 (ESP-12E module), featuring a CP2102 USB-to-UART bridge for reliable programming and debugging. It integrates GPIO, PWM, I2C, 1-Wire, and ADC on a single breadboard-friendly board, and can be programmed with the Arduino IDE or NodeMCU Lua firmware.
The R2 version improves on the original with a CP2102 USB chip (replacing CH341) for better driver compatibility, higher current support, and a slimmer form factor that fits directly on a standard breadboard.
