CoAction Hero is a tiny board based on an ARM Cortex-M3 micro-controller (NXP LPC1759), that makes use of CoActionOS ecosystem that includes the hardware, but also an open source RTOS allowing multiple app to run concurrently, and a graphical interface to communicate with the board.
First, let’s have a look at the hardware specs:
- Micro-controller – NXP LPC1759 ARM Cortex-M3 processor @ 120MHz with 64kB RAM and 512kB Flash ROM.
- Storage – 1MB serial flash chip (pre-loaded with CoActionOS)
- Expansion port
- micro USB connector.
- 40 I/O pins are available on both sides of the board, and the board can be inserted in a breadboard.
CoActionOS RTOS will come pre-loaded on the board, and if you don’t want to, you don’t even need to know it’s there, and it’s use will be transparent. But let’s have a quick look at this real-time OS, which allows multitasking on Cortex M3 MCU, supports an unnamed filesystem, and they also provide a C/C++ library to help with hardware peripherals (GPIO, ADC, SPI, UART,…) programming.
Documentation, source code, and tutorials are available on CoActionOS website.
The desktop development environment, based on Qt 4.8 and GCC, currently runs on Windows and MacOS, with Android and iOS support coming once Qt 5.x is available for those mobile OS. Linux may also be supported at a later stage. The board connects to your computer via its micro USB port, and CoActionOS Link software allows you to browse the board’s filesystem, provides terminal access, install programs, re-flash the kernel, and monitor running processes. They recommend using Eclipse for compiling programs.
Several example projects are showcased on their kickstarter page such as driving a 1.8″ LCD, a DC Motor with PWM and PID, and an LED strip.
You can pledge as low as $29 to get the CoAction Hero board with a USB cable, and with a $99 pledge, you can add the Bluetooth and LCD expansion boards. Devkits should ship to backers in July 2013.
