Technological Arts introduces Esduino12, the first in a line of new products conforming to the popular open-source Arduino hardware form-factor. Based on the popular 16-bit Freescale 9S12C microcontroller, Esduino12 offers enhanced capability and programming flexibility over existing Atmel-based designs, yet retains hardware compatibility with the growing number of available Arduino application shields.
Esduino12 is programmable in assembler, BASIC, and C. For assembler and C programming, Freescale's free Special Edition of CodeWarrior for Windows is a popular choice. For those who prefer BASIC, the object-based Windows-hosted nqBASIC language is available free of charge from www.nqBASIC.com. A port of the Arduino development environment to the S12 is currently underway, as a community project.
With a base price of only $39, Esduino12 offers plug-in options for both USB and wireless XBee communications (no shield required), and provides simple three-way routing that enables the user to choose USB-to-XBee, USB-to-MCU, or XBee-to-MCU communications. Both 3.3V and 5V regulators are provided on-board, giving added utility to the design.
While a standard BDM connector is provided for advanced users, the Freescale Serial Monitor (i.e. bootloader) comes factory-programmed into the 9S12C chip, so that a BDM pod is not required for basic erasing and programming operations.
Two product configurations are being offered: #ESD12C32 ($39), with 32K flash and 2K RAM; and #ESD12C128 ($49), with 128K flash and 4K RAM. The optional USB-to-TTL interface (#USB2MCU) is $15.50, and a plug-in carrier for XBee modules (#ADXB-RA) is $7.50.
For easy implementation of custom applications, a selection of four new Arduino-compatible $10 prototyping shields has also been announced. These shield designs maximize use of the available board area, and are optimized for applications involving narrow and wide DIP packages, LED displays, and discrete through-hole components.
Further details on Esduino12 and Arduino-compatible prototyping shields may be found on the company's web site, at www.TechnologicalArts.com.
