Overview

Nu-LB-Mini51 is the specific development tool for the NuMicro Mini51 series. Users can use Nu-LB-Mini51 to learn easily how to display information, store data, communicate with PC, and interact with humans through the Mini51 series. Besides, it also integrates an ICE controller called Nu-Link-Me and users do not need other additional ICE or debug the equipment.

Nu-LB-Mini51 Introduction
Nu-LB-Mini51 uses the Mini54LAN as the target microcontroller and includes rich functional blocks on board. Figure 2-1 is the positive and negative Nu- LB-Mini51. The positive Nu-LB-Mini51 includes a main chip (Mini54LAN), INT key, reset key, variable resistance, RGB LED, 8 LEDs, 128×64 Dot Matrix LCD and RS232 interface. The negative Nu-LB­Mini51 includes EEPROM, Flash, and an ICE controller called Nu-Link-Me.
Nu-LB-Mini51 is similar to other development boards. Users can use the functional blocks connected with Mini54LAN to develop and verify applications to emulate the real behavior. The onboard chip covers Mini51 series features. The Nu­LB-Mini51 can be a real system controller to design users’ target systems.
Nu-Link-Me is a Debug Adaptor. The Nu-Link-Me Debug Adaptor connects your PC’s USB port to your target system (via Serial Wired Debug Port) and allows you to program and debug embedded programs on the target hardware. To use the Nu- Link-Me Debug adaptor with IAR or Keil, please refer to “Nuvoton NuMicroT” IAR ICE driver user manual “or Nuvoton NuMicron‘ Keil ICE driver user manual” in detail. These two documents will be stored in the local hard disk when the user installs each driver.nuvoTon NU LB MINI51 Arm Cortex-M0 32 Bit
