Product Info

Esduino is an Arduino-style board based on a 9S12C microcontroller! What this means is that you can now easily utilize the powerful Freescale 16-bit 9S12C microcontroller in your projects by using any of a great number of Arduino shields already available from various sites worldwide. And if you can't find one that exactly matches your needs, you can always design your own, using the open-source hardware design files you'll find on the internet.

Since it is based on S12, your code can be developed using any S12 tools (e.g. CodeWarrior, AsmIDE, GCC, ICC12, etc.). For those who prefer the Arduino development environment, a community project is currently underway to port it to 9S12C. If you're interested with this project in getting involved, please contact us.

Esduino12C32-UR features:

• 9S12C32 16-bit microcontroller
  • up to 24MHz bus speed (with PLL enabled)
  • 32K flash and 2K RAM
• on-chip Serial Monitor (bootloader)
• jumper-selectable mapping of Arduino-defined PWM pins. This lets you choose the source for these pins in your application.
• two additional analog-to-digital channels available (PAD06 and PAD07), which can also function as digital inputs or outputs
• two additional digital I/O pins brought out (PM0 & PM1), which can be used for CAN interface, if desired
• SPI pins also brought out to a single connector, for use with SPI peripherals, such as ShiftBrite and soon-to-be-announced products
• on-board USB interface retrofit provides 5V to power all circuitry (poly-fuse protected)
• external power jacks (barrel and 2-pin Molex) to accommodate alternative power source when USB not connected (e.g. batteries)
• connector for optional ADXB adapter (see Accessories) supports low-cost addition of XBee radio module (purchase separately).  No XBee shield required!
• on-board 5V and 3V regulators supply all circuitry, and also power any application shields that you plug in
• fully compatible with free nqBASIC programming language
• compatible with all other 9S12 programming environments (CodeWarrior, AsmIDE, Eclipse, etc.)

What you get:

• assembled and tested Rev.2 Esduino board, with USB retrofit
• printed feature sheet and schematic diagram

*Note: ADXB feature non-functional on Rev. 0 and 1 boards. See schematic for details.

Product Details

  Not familiar with Arduino?
Arduino is an open-source physical computing platform based on an Atmel 8-bit microcontroller. Originating in Italy, it has become very popular worldwide over the past couple of years. The creators of Arduino refer to any application board designed to plug into it as a "shield". Many shield designs were created using the free version of CadSoft's Eagle schematic capture and circuit board layout program. If you want to design your own board, you can download Eagle and any of the open-source design files you'll find on the internet. Then you can modify them to suit your needs, and use a PCB prototyping service to have the boards fabricated for you.

If you don't want to layout a PCB, you can always opt to build your application by hand using point-to-point wiring with one of our many Prototyping Shield designs.
