Quail (https://www.mikroe.com/quail, PID: MIKROE-1793) is based on an STM32F427VI CPU, featuring 2048 kB of Flash memory and 192 kB of RAM. An on-board Cypress S25FL164K adds 8 MB of SPI Flash. Quail has 4 mikroBUS(TM) sockets for Mikroe click(TM) board connectivity, along with 24 screw terminals for connecting additional electronics and two USB ports (one for programming, the other for external mass storage). 4 UARTs, 2 SPIs and 1 I2C bus are available for communication.
