Description

TM4C123GH6 Development Board –( Professional Grade Rugged, Practical, Student-Friendly)

With On-Board CMSIS-DAP Debugger, USB-Serial Converter, CAN Transceiver & Robust Power System

This development board is a powerful, feature-rich platform designed for engineers, students, and professionals working with TI TM4C123G ARM Cortex-M4F microcontrollers.
It provides robust debugging, built-in communication interfaces, a CAN bus transceiver, strong power protection, and durable connectors—making it significantly more advanced and reliable than typical Tiva-C LaunchPad alternatives.

Key Features

TM4C123GH6 – ARM Cortex-M4F MCU (LQFP-64)

• 80 MHz 32-bit MCU

• Floating-point unit (FPU)

• 256 KB Flash, 32 KB SRAM

• Rich set of timers, ADC, UART, SPI, I2C, PWM, USB Device

Integrated CMSIS-DAP Debugger (On-Board)

Your board includes a built-in CMSIS-DAP debugger, so no external programmer is required.

• Connects via USB Type-B (much stronger and more durable than micro-USB)

• Supports SWD debugging

• Jumper-selectable SWD interface → can be used:

  • With this TM4C123 board

  • OR with any external ARM MCU board

• LEDs for RUN and MODE status

• Built-in USB to UART bridge in the debugger

• UART0 TX/RX can also be routed via jumpers to any project hardware

CAN Bus Interface (TJA1050 Transceiver)

A full CAN interface is integrated using NXP TJA1050.

• CANH / CANL screw terminal output

• CAN TX / RX mapped to PE4 / PE5 through jumpers

• 120 Ω termination selectable by jumper

• The entire CAN circuitry can also be used with external MCUs

Flexible Power System

A reliable industrial-grade power stage:

• DC-Jack input (7–12V supported)

• USB device port + USB host (debugger) ports

• High-efficiency 5V and 3.3V regulators

• PPTC resettable fuse on 5V line for safety

• Multiple power test points

• Power LED indicator
