The 30-Pin ESP-32 Development Board Wifi + Bluetooth is a small wireless microcontroller board that has the ESP-32 chip from Espressif. It is made for students and developers who need WiFi and Bluetooth connections in a smaller pin-count form factor than the 38-pin versions.
The development board is based on the esp wroom 32 chip architecture. It has a dual-core processor and can connect to WiFi and Bluetooth at 2.4 GHz on a single module. connect to digital I/O, multiple ADC channels, hardware UART, SPI, and I2C interfaces through 30 GPIO pins. This means it can connect to a lot of different sensors and other modules.
The Type-C USB port that works with the CP2102 UART bridge is a useful new feature in this version. The Type-C connector is better than older port types for connecting things over and over again. The CP2102 chip also makes sure that serial communication stays stable while you program and debug.
The board operates between 2.2V and 3.6V, which aligns with the ESP32 chip’s native voltage requirements. It can be powered directly through the USB Type-C port or through regulated external supply connected to the VCC pin.
From a software perspective, this esp32 nodemcu compatible board works with Arduino IDE using the 30-Pin ESP-32 Development Board Wifi + Bluetooth package, and also supports ESP-IDF for more advanced firmware development. The combination of wireless capability and hardware interface support makes it a practical choice for building sensor nodes, remote controllers, and connected automation devices.
Available through StemVolt, this esp board is commonly used by IoT developers and engineers who need a wireless-capable microcontroller in a compact and modern form factor for real-world project builds.
