A newer version of the module is available in our offer under the name:

SparkFun Pro Micro - board with RP2040 microcontroller

Description

SparkFun Pro Micro is a board equipped with the RP2040 microcontroller designed by the Raspberry Pi foundation. The system has two ARM Cortex M0 + cores operating at a frequency of 133 MHz, 256 KB of RAM and 30 GPIO ports. The microcontroller is not equipped with flash memory, but on the board there is an external memory with a capacity of 16 MB connected via the QSPI interface.

On the board, in addition to the RP2040 system and Flash memory, the user will find a 3.3 V voltage stabilizer, Boot and Reset buttons, power and RGB WS2812 LEDs, a USB type C connector for powering and programming the module, and 20 GPIO outputs with such parameters such as four 12-bit ADC inputs, 10 PWM outputs, I2C interface, SPI and two UART interfaces. The I2C bus is also available on the Qwiic connector.

The platform supports the popular MicroPython and C/C++ programming languages. Programs can be loaded to memory via the USB interface using the built-in UF2 bootloader. The guide with examples of use is available on the product page.
