Review: Jastoo 2012 R3 ARM 32-bit Main Control Development Board - Review

Introduction

The Jastoo 2012 R3 ARM 32-bit Main Control Development Board offers a plethora of features and functions for electronics enthusiasts and developers. With a focus on performance and compatibility, this development board promises to be a versatile tool for various projects.

Features and Specifications

The Jastoo main control board module contains a SAM3X microcontroller with 512 KB of Flash memory, 96 KB of SRAM, and pre-burned bootloader in ROM. This ample storage space allows for storing user programs and facilitates quick and efficient operations. Its digital I/O pins range from 0 to 53, providing flexibility for input and output operations at 3.3V levels.

Functionality

With support for functions such as pinMode(), digitalWrite(), and digitalRead(), each IO pin can be programmed as an input/output port. The board also features special pins for serial communication (Serial 0, 1, 2, 3), PWM output (pin 2 to 13), SPI interface for communication with other devices, and analog inputs (A0 to A11) with 12-bit accuracy. Additionally, the board includes support for TWI communication and a built-in LED on pin 13 for visual feedback.

Compatibility and Expandability

The Jastoo 2012 R3 ARM board shares the same shape as the Arduino Mega 2560, ensuring compatibility with existing expansion boards. This allows users to easily integrate the board into their projects without any major modifications. The presence of CANRX and CANTX pins showcases support for CAN bus communication, although the API for this feature is currently unavailable.

Performance and Usability

In terms of performance, the SAM3X microcontroller provides a robust platform for developing complex projects requiring high-speed operation. The board's hardware features, such as PWM output and analog inputs, make it suitable for a wide range of applications. However, users should be cautious about voltage levels, as the board operates at 3.3V and may get damaged if exposed to higher voltages.

Conclusion

Overall, the Jastoo 2012 R3 ARM 32-bit Main Control Development Board offers a comprehensive set of features and functionalities for electronics enthusiasts and developers. With its ample storage space, versatile I/O options, and compatibility with existing expansion boards, this board is a promising choice for those looking to embark on intricate electronics projects. While there are minor limitations, such as lack of CAN bus API, the board's performance and usability make it a valuable addition to any developer's toolkit.
