OVERVIEW

GebraBit ATMEGA32A is a CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture  Module.

GebraBit ATMEGA32A operates with 3V3 or 5V Supply Voltages that users can easily select with the Considered onboard jumper selector. This feature helps to use a wide range of sensors and IC for interfacing with this module.

Because of the integrated 3V3 regulator, just 5V input voltage is sufficient for powering the module on. Users can also program the microcontroller through the ICSP (In-Circuit Serial Programming) header.

One of the important points about GebraBit ATMEGA32A is the capability of AREF (ADC Analog Reference) voltage selection due to the “AREF SEL” jumper selector. User can choose AREF voltage among AVCC, Internal reference voltages of nominally 2.56V, and external voltage from Considered on-board potentiometer or ARF pin.

Thanks to the embedded USER&RESET button, USER LED, and access to all pins of the ATMEGA32A microcontroller, GebraBit ATMEGA32A  will be the best choice for developing any kind of project, In addition, if you know it can be developed in Arduino environment so easy!

Finally don’t forget that this module is Pin Compatible with GEBRABUS , Such that all alternate function like I2C, SPI,… is exactly pin compatible with GEBRABUS. As a result, all GebraBit Module (Sensors, Interface,..) can sit on GebraBit ATMEGA32A and get ready to be initialized.

As its clear, the module core is, ATMEGA32A, A low power, CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. The ATmega32A is a 40/44-pin device with 32 KB Flash, 2 KB SRAM and 1 KB EEPROM. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching one million
instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.

WARNING: FOR ACCURATE INFORMATION ABOUT ICs ABSOLUTE MAXIMUM RATINGS AND ITS PRECIOUS  CHARACTERISTICS RANGES, USERS MUST CERTAINLY REFER TO ICs MANUFACTURE DATASHEET.
