产品详情

The MAX32625PICO2 board is a rapid development platform designed to help engineers quickly implement designs with the MAX32625 Arm^® Cortex^®-M4 microcontroller with FPU. The board breaks out bootloader-specific serial interfaces through a 0.1in pitch, 2x7-pin header to allow easier connection to target boards. The board also includes the MAX14750 PMIC to provide all of the necessary voltages. A 10-pin Cortex debug connector allows usage as a DAPLink adapter. Additionally, on board are an RGB indicator LED and pushbutton. This provides a power-optimized flexible platform for quick proofs-ofconcept and early software development to improve time to market.

The MAX32625PICO2 board ships with a customized DAPLink image loaded that provides the standard DAPLink features of the USB Mass Storage Device (MSD) drag-and-drop programming, USB Communications Device Class (CDC) virtual serial port, and Human Interface Device (HID) CMSIS-DAP interface. This allows the board to be connected to another target platform to enable debugging. Additionally, it acts as a USB-to-I²C/ SPI/UART bridge to provide required interfaces with the target bootloaders. The microcontroller is also programmed with a bootloader, allowing the DAPLink image to be updated or replaced with your own application code.
