The Advantages of SP32 Microcontrollers
Energy Efficiency and Low Current Regulation
The SP32 microcontroller is equipped with an internal regulator that efficiently regulates low currents as low as 5 microamperes, making it ideal for deep sleep mode. This energy-saving feature allows the microcontroller to wake up quickly through GPIO interruptions, ensuring optimal power usage. Additionally, the SP32 microcontroller comes with an internal timer and ABC measurements, as well as touch sensors and capacitive functions in its peripherals, making it a versatile choice for various projects.
Improved Wireless Connectivity
One notable advantage of the SP32 microcontroller is its built-in Wi-Fi connection. The latest versions of the microcontroller even come with the option to install an external antenna, significantly enhancing the range of Wi-Fi signals. This feature opens up new possibilities for projects that require reliable wireless communication.
Considerations for Prototyping
While the SP32 microcontroller offers numerous benefits, there are a few drawbacks to consider when it comes to prototyping. One challenge is the width of the microcontroller, which may not fit properly on a standard protoboard. In such cases, users may find that only one row of pins can be connected, either on the top or bottom. However, this can easily be resolved by purchasing a smaller protoboard or using special bases that allow for easier connection and manipulation of the microcontroller.
Working with Different Voltage Levels
The SP32 microcontroller operates at 3.3 volts, which can sometimes be limiting when working with peripherals that require 5 volts. To address this issue, bidirectional level converters that convert the voltage from 3.3 volts to 5 volts are necessary. These converters ensure proper voltage coupling and prevent damage to the microcontroller. It’s important to be aware of this requirement to avoid potential issues when connecting various sensors and actuators.
