TI’s LaunchPad boards have a history of being both low cost and fully featured. There’s a board for each of TI’s major processor lines, and all of them support the same “BoosterPack” interface for additional functionality. Today, TI has announced a new LaunchPad based on their new Tiva C ARM processors, which is designed for connectivity.
The Tiva C Series Connected LaunchPad is based on the TM4C129x processor family. These provide an ethernet MAC and PHY on chip, so the only external parts required are magnetics and a jack. This makes the Connected LaunchPad an easy way to hop onto ethernet and build designs that require internet connections.
This development board is focused on the “Internet of Things,” which it seems like every silicon manufacturer is focusing on nowadays. However, the real news here is a low cost board with tons of connectivity, including ethernet, two CANs, 8 UARTs, 10 I2Cs, and 4 QSPIs. This is enough IO to allow for two BoosterPack connectors that are fully independent.
For the launch, TI has partnered with Exosite to provide easy access to the LaunchPad from the internet. A pre-loaded demo application will allow you to toggle LEDs, read button states, and measure temperature over the internet using Exosite. Unlike some past LaunchPads, this one is designed for easy breadboarding, with all MCU pins broken out to a breadboard compatible header.
Finally, the price is very right. The board will be release at $19.99 USD. This is less than half the price of other ethernet-ready development boards out there. This makes it an attractive solution for hackers who want to put a device on a wired network, or need a gateway between various devices and a network.
