Clicker 2 for STM32 is a compact development board featuring an ST Microelectronics STM32F407VGT6 32-bit ARM Cortex-M4 microcontroller and two mikroBUS host sockets that allow you to plug in any two out of more than 90 different plug-and-play peripheral modules (called Click boards). The STM32 chip comes preprogrammed with a fast USB HID bootloader, so you can load code into it without needing an external programmer.
If you want to use an external programmer, pads are available on the board for installing a header compatible with the mikroProg-STM32. Pin headers are included for this purpose.
The board also has two rows of pads (26 pins each, pin headers included) for connection to external electronics (compatible with mikromedia shields), and a LiPo battery connector (for Molex 5264-2P). An LTC3586-2 power management IC allows charging of a connected battery via USB and can provide an independent power supply to the MCU's real-time clock even when the board's power switch is off. The mikroBUS host connectors consist of two 1×8 female headers with SPI, I2C, UART, RST, PWM, Analog and Interrupt lines as well as 3.3V, 5V and GND power lines.
Rounding off the board's features are some buttons (two User; one Reset), LEDs (two User; Power; Charge Status), and pads for connecting your own external on/off switch if the on-board switch is not convenient (e.g. if the board is going into an enclosure).
The user LEDs can be used for visual indication of the logic state on pins PE12 and PE15. The user buttons are connected to PE0 and PA10.
The board measures 60.4 × 80.9 mm (2.4 × 3.2 inches). Without any mikroBUS modules installed, it weighs 26 grams (0.057 lbs).
