Open4337-C Standard, LPC Development Board

Description

Overview
Open4337-C is an LPC development board designed for the LPC4337JBD144 microcontroller, consists of the mother board and the MCU core board Core4337.

The Open4337-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.
