ESP32-based SparkFun Thing Plus SkeleBoard For A Wide Range of Applications

Due to the expanded capabilities offered by every ESP32 processor coming to market, many designers and manufacturers realize the importance to unveil ESP32-based development boards in various form factors. Recently, SparkFun released a limited edition of the Thing Plus SkeleBoard based on the ESP32 WROOM (U.FL) that targets a wide range of applications ranging from low-power sensor networks to voice encoding and music streaming.

The motivation behind designing this board enables developers to get started with Espressif IoT ideations through a powerful yet generic onboard system-on-chip. The ESP32 WROOM features the Xtensa dual-core 32-bit LX6 microprocessor with a decent wireless connective through Wi-Fi, Bluetooth, and BLE modules. The processor is clocked at up to a frequency of up to 240 MHz with 520kB internal SRAM. There also comes a small 16MB of flash storage to save programs for targeted applications.

At the heart of the onboard ESP32 WROOM SoC is the ESP32-D0WDQ6 chip module is embedded to be scalable and adaptive. Even though there are two CPU cores, both can be manually controlled and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. With the low-power mode, the developer can power off the CPU and allow the co-processor to monitor the interfacing peripherals. Let us take a detailed look at the specifications of the SparkFun Thing Plus Skeleboard.

Specifications of SparkFun Thing Plus SkeleBoard:

• SoC: ESP32 WROOM featuring Xtensa® dual-core 32-bit LX6 microprocessor at up to 240 MHz clock frequency.
• Memory: 520kB internal SRAM
• Storage: 16MB of flash storage expandable with SD card interface
• Wireless Connectivity: Wi-Fi+BT+BLE
• Interfaces: Ethernet, high-speed SPI, UART, I2S and I2C
• Connector: JST connector (LiPo battery) and a U.FL connector
• GPIOs: 21 GPIO
• Power: 2.3 to 3.6V operating range
