SparkFun ESP32 Qwiic Pro Mini Review: Power-packed Performance in a Tiny Package - Review

Introduction to the SparkFun ESP32 Qwiic Pro Mini

If you're looking for a compact yet powerful development board for your next embedded systems project, the SparkFun ESP32 Qwiic Pro Mini is a game-changer. This innovative board houses the ESP32 Pico Mini from Espressif, offering a range of features and capabilities that make it stand out in the world of microcontrollers.

Features and Performance

The SparkFun ESP32 Qwiic Pro Mini boasts a dual-core 32-bit LX6 microprocessor with individually controllable CPU cores and adjustable clock frequency. It also includes a co-processor for tasks requiring minimal computing power, along with a rich set of peripherals such as an external SD card interface, capacitive touch sensors, ADC, DAC, and various communication interfaces like UART, SPI, I2C, and more.

Technical Specifications

The board features the ESP32-PICO-V3-02 embedded module with 448KB ROM, 520KB SRAM, 16KB RTC SRAM, 8MB SPI flash, and 2MB PSRAM. It operates on an input voltage of 3.0-3.6V, making it suitable for a wide range of applications. With a sleep current of less than 5μA, it's ideal for battery-powered and wearable electronics projects.

Ease of Programming

One important point to note is that unlike other ESP32 boards, the SparkFun ESP32 Qwiic Pro Mini requires user interaction to program. To initiate programming mode, you need to hold down GP0 while resetting the device. While this process is straightforward, it's worth mentioning that it's not automatic.
