A compact 2.5"x4" board, this simple SBC provides all the I/O of the Freescale MC9S12A512 processor chip, including dual logic-level and standard RS-232 serial ports, 10-bit resolution analog inputs, I2C, dual SPI links, PWM, and timer-controlled digital I/O. The PDQ Board Lite is powered by +5 Volts delivered via one of the I/O headers or from a standard micro-USB connector, the same type used on many cell phone chargers.
The PDQ Board Lite is programmed using the C language. It contains an embedded RTOS in firmware and is programmed using a C integrated development environment (IDE). The Mosaic IDE+ is a comprehensive GNU environment that simplifies the coding of any multitasking application and allows users to edit, compile, download, interactively debug, and run application programs.
