Talk about the difference between STM32F103 and STM32F107

It seems you wanted to attach an image, but I don't see one yet. Could you try uploading it again?

In the meantime, here's a comparison between STM32F103 and STM32F107 based on their features and key differences:

STM32F103 vs STM32F107: Key Differences
Both microcontrollers belong to the STM32F1 series (ARM Cortex-M3 core), but they target slightly different use cases.

Image description

1. Ethernet Support
The STM32F107 has a built-in 10/100 Ethernet MAC (Medium Access Control), enabling it to support network communication.
STM32F103 lacks Ethernet support.
This makes the STM32F107 suitable for applications involving networking protocols like TCP/IP or embedded servers.

2. Memory
The STM32F107 has more SRAM (64 KB) compared to 20 KB in most STM32F103 models.
Flash memory for the F107 tops out at 256 KB, while the STM32F103 series has variants with up to 512 KB.

3. USB Support
STM32F103 supports USB device mode.
STM32F107 supports USB OTG (On-The-Go), allowing it to act as both a host and a device.

4. Target Applications
STM32F103:
General-purpose microcontroller for applications like motor control, industrial automation, and portable devices.

STM32F107:
Designed for applications requiring connectivity, such as:

Ethernet-based systems
Networked industrial devices
Embedded web servers

Summary
If your application involves Ethernet connectivity, the STM32F107 is the better choice. For simpler, general-purpose applications without network requirements, the STM32F103 is sufficient and may be more cost-effective.
