Quail is an STM32-powered development solution for building hardware prototypes with click boards and C# managed code. It brings together click boards and Microsoft’s .NET Micro Framework for embedded devices (NETMF). Write code for your Quail projects in Microsoft Visual Studio (free in the community edition); drivers for individual click™ boards are provided by the MikroBUS.NET team.
Hardware-wise, Quail has 4 mikroBUS™ sockets for click board connectivity, along with 24 screw terminals for connecting additional electronics and two USB ports (one for programming, the other for external mass storage). The board runs on a 5V power supply.
