LuaNode32
LuaNode32 is a compact ESP32-based development board built on the ESP-WROOM-32 module, housing Espressif’s dual-core Xtensa LX6 processor with 520 KB SRAM, 4 MB SPI flash, integrated 2.4 GHz Wi-Fi, and Bluetooth 4.2 with BLE. The board exposes GPIO, UART, SPI, I2C, ADC, DAC, and PWM interfaces through standard headers, and a USB-to-serial chip simplifies programming and monitoring. Wi-Fi and MQTT connectivity enable direct integration with IoT platforms for telemetry and remote control.
Overview
The LuaNode32 is a compact development board built on Espressif’s ESP-WROOM-32 module. It features a dual-core Xtensa LX6 processor with variable clock frequency from 80 MHz to 240 MHz, integrated Wi-Fi 802.11 b/g/n, Bluetooth 4.2 Classic and BLE. The miniature 25.5 mm × 18 mm form factor includes on-board Flash memory, a 40 MHz crystal oscillator, and a PCB antenna — making it well-suited for portable and autonomous IoT applications.
