Open4357-C is an LPC development board designed for the LPC4357FET256 / LPC4357JET256 microcontroller, consists of the mother board and the MCU core board Core4357.
The Open4357-C supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with NXP LPC series microcontrollers.
