RP2040 mikroBUS Development Board - the board with the RP2040 microcontroller

Description

The board is 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, 264 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.

The module is equipped with a mikroBUS connector that contains two 8-pin female connectors. It offers communication interfaces (SPI, UART and I2C), six additional pins (PWM, Interrupt, Analog input, Reset and Chip select) and two power groups (3.3V and 5V).

In addition to the Thing Plus pin layout, the board also has a microSD card slot, single-cell JST battery connector (with charging circuit and charge flow sensor), addressable RGB LED WS2812, JTAG PTH pins, four (4-40 screws) mounting holes and Qwiic connector.

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