The BDMICRO MAVRIC-IIB is a powerful microcontroller board based on the ATmega128 MCU. It is fully programmable using familiar languages such as C and BASIC. The GNU GCC C compiler is very popular as it comprises the core of the de facto standard tool chain of the open source community , including Arduino programming and libraries.. Additionally, MCS Electronic's BASCOM-AVR BASIC compiler is also very popular, economical, and highly regarded by AVR enthusiasts.
The MAVRIC-IIB is the perfect microcontroller for many applications such as robotics where a fusion of many sensors and digital I/O are needed. Its copious program and data space allow you to implement sophisticated algorithms and logic without having to compromise features. MAVRIC-IIB's 8 channel, 10-bit A/D converter makes short work of reading analog sensors like the SHARP GP2D12 IR distance sensor. It has 2 on-board UARTs both of which are level-shifted to provide true RS232 levels, or they may be used using the unshifted TTL levels if that is more convenient. One of the UARTs can optionally be run as an RS485 interface which incorporates on-board termination and independent transmitter/receiver control for sophisticate bus communication protocols. MAVRIC-IIB is I2C ready out of the box with on-board pull-ups so you can hook up your existing I2C sensor, control, and display devices, and many other I2C peripherals. In addition to all that, 6 high resolution PWM outputs are available for driving servos and PWM motors with high precision. And with up to 51 digital I/O pins, it can handle even the most complex and demanding control tasks.
The MAVRIC-IIB also includes 6 R/C servo headers for controlling servos directly. An auxiliarly power input is provided to power the servos seperately from the microcontroller electronics which protects the on-board electronics from the high current drain and assocated brown-outs that can result from powering motors and electronics from the same power supply.
The on-board standard programming headers make development easy - 10-pin serial ISP header for connecting to your AVRISP or STK500, and also the standard 10-pin JTAG header for using your JTAGICE for programming and single-step, source level debugging.
The MAVRIC-IIB incorporates an advanced, on-board, low-dropout voltage regulator and can be powered with as little as 5.5 Volts. Four mounting holes are provided for securely mounting your board, and with its small size of 2.2 x 3.6 inches, you can mount it just about anywhere.
Let this microcontroller be the brain of your next project!
