[Jihai APM32F407 Tiny Board] 1. Unboxing and Review [Copy link]

 

APM32F407 Tiny Board is equipped with a 32-bit industrial-grade high-performance APM32F407 MCU based on the Arm Cortex-M4F core, with a working frequency of 168MHz , Flash 1MB, SRAM 192+4KB, and is one of the ideal choices for domestically produced alternatives to STM32F407. Compared with STM32F407, APM32F407 has added hardware support for national encryption algorithms , which is very suitable for occasions that require secure encryption. The development board packaging is very nice, and no cheap paper box is used:

The back of the board introduces the chip features and onboard resources: it supports the real-time systems Free RTOS and RT-Thread . The available development tools include Keil MDK-ARM, IAR Embedded Workbench, Visual Studio Code, and Eclipse. The official website provides instruction manuals, schematics, SDKs, etc. to help developers get started quickly.

The front view shows a development board made of high-end black immersion gold. I have two complaints here: First, the board itself is very exquisite, but it uses two huge plug-in crystals, which is very inconsistent and reduces the beauty. Second, the onboard debugger uses two 5P*2 pins, and the wiring is directly connected together. Why not learn from the STM32 board? One 5P*2 pin can be disconnected from the onboard connector and the onboard main chip with a jumper. What is the use of a design like the one shown below? ? ?

Back side: Very smooth, beautiful wiring

The official website download page has very clear classification:
