The 38 Pin ESP-32S Development Board Wifi + Bluetooth and is a functional wireless microcontroller board based on the ESP-32 chip. It is one of the most powerful and popular development platforms in the embedded electronics community. It has a lot of processing power, wireless connectivity, and support for many peripherals, all in a small package.
It is on the esp32 wroom board, which houses a dual-core 32-bit processor running at up to 240 MHz. The integrates 2.4 GHz WiFi and Bluetooth radio hardware, which means your project gets wireless capability without sourcing and wiring separate communication modules.
The 38 GPIO pins on this board expose nearly every available signal of the ESP-32 chip. This includes multiple ADC input channels for analog sensor reading, two DAC output channels, capacitive touch inputs, and hardware interfaces for UART, SPI, and I2C communication. This level of peripheral access makes the 38 pin dev board suitable for projects that need to connect multiple sensors and electronics modules simultaneously.
Programming is handled through the onboard USB Type-C port, which connects to the CP2102 UART bridge. This setup allows direct sketch uploading from Arduino IDE or ESP-IDF without any external programmer. The Type-C connector also handles 5V power input, which is internally regulated to match the ESP-32 chip operating requirements.
This board is available from StemVolt and is popular with developers, esp32 for engineering students and robotics builders that need a stable and well-supported wireless development platform for building real-world projects.
