Here we will be listing some of the limitations or generic comments you see on a Raspberry Pi board. Most comparison will be with the microcontrollers and peer boards and not high processing boards.
- Raspberry Pi boards do not have Analog interface. So, if we want to interface Analog input to Raspberry Pi board we have to use external ADC
- Raspberry Pi has limited PWM pins. If we see the pin out, there are 4 PWM options but internally, there are only two PWM pins. It meant 2 pins are duplicated and extended to GPIO header
When compared with high performance boards, below are the limitations:
Limited Processing Power:
Raspberry Pi boards are relatively low-powered compared to full-fledged desktop computers or laptops. While they are capable of running various applications and performing basic tasks, they may struggle with resource-intensive processes or demanding software.
Limited RAM:
Raspberry Pi boards usually come with a limited amount of RAM, typically ranging from 1GB to 4GB. This can constrain the performance of certain applications or multitasking capabilities, especially when dealing with memory-intensive tasks.
Lack of High-End Graphics:
Raspberry Pi boards utilize integrated graphics, which are not designed for high-end graphical processing. This makes them less suitable for tasks like gaming or running graphics-intensive software.
Limited Storage:
Most Raspberry Pi models rely on microSD cards for storage, which have smaller capacities compared to traditional hard drives or solid-state drives. This limitation can affect the amount of data you can store locally on the device.
Lack of Power for Certain Applications:
Due to its limited processing power, Raspberry Pi may not be suitable for certain resource-demanding applications or real-time processing tasks. This includes complex simulations, large-scale data analysis, or running multiple virtual machines simultaneously.
Software Compatibility:
Although the Raspberry Pi ecosystem has grown significantly, not all software applications are compatible with the ARM-based architecture used by Raspberry Pi. This means that some software, particularly proprietary or specialized programs, may not be readily available or may require additional effort to install and configure.
Connectivity Limitations:
While Raspberry Pi offers built-in Wi-Fi and Bluetooth capabilities, the range and performance may not be as robust as dedicated networking devices. Additionally, Raspberry Pi may have limited USB ports, which can limit connectivity options for peripherals and devices.
Reliance on Community Support:
Raspberry Pi has a vibrant and active community, but the official support channels are limited compared to mainstream computing platforms. Relying on community support may require more effort and troubleshooting skills, especially for complex issues.
